Technical Field

The present invention relates to the field of power system automation, and in particular to a one-key sequential control automatic calibration method based on a substation SCD model file.

Background technique

The one-button sequential control test system for smart substation is a test system that aims to verify the feasibility and correctness of the one-button sequential control system for smart substation. It is an important inspection part in the promotion and use of the one-button sequential control system for smart substation.

First, the current one-button sequential control verification method relies heavily on manual operations in data configuration and actual verification, and there are many manual errors during configuration. In addition, the existing one-button sequential control verification method without power outage often requires a lot of time to debug during testing with the actual on-site sequential control host. Secondly, the SCD model file has a large amount of data, and a lot of data information does not involve one-button sequential control, which causes data redundancy and time-consuming configuration work.

The invention patent with publication number CN110989547A mentions a detection method and system for a one-button sequential control system of an intelligent substation, which uses a device state migration method to migrate the device state of the device under test, realizing the logical decoupling of the device state and the current test device, and uses the SCD model for data distribution to achieve the unification of test data and communication methods. The simulated sequential control host is a one-button sequential control test device, which plays different roles based on the different states of the tested object. It still needs to be connected to the actual device under test when used, and has actual requirements for the on-site test environment.

Detailed ways

In order to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

As shown in FIG1 , the one-key sequential control automatic calibration method based on the substation SCD model file of the present invention comprises the following steps:

S1 lists the primary equipment information table in combination with the primary equipment main wiring diagram, determines the IED attributes in the SCD model file, parses the SCD model file, and obtains the configuration description information in the SCD model file. The configuration description information retains the data required for one-key sequential control verification according to the IED attributes, including at least key attributes such as switch device type, switch device name, and bay name.

Among them, the primary equipment information table contains all the switchgear involved in the one-button sequential control. The SCD file in the IEC61850 standard system follows the "IEC61850-6 Substation Communication Configuration Description Language SCL" specification and is important data relied on for substation equipment operation, daily operation and maintenance, and engineering management. The SCD model file generated by modeling according to the IEC61850 specification is used to describe the information of the primary and secondary equipment of the entire substation.

S2 parses the configuration description information, extracts switch device attribute information, and constructs a switch topology diagram of all bays in the entire substation.

In this embodiment, the configuration information is parsed to extract the switch device attribute information, as shown in FIG2 , including:

S21 determines the IED attributes according to the naming rules of the current switchgear through keywords and/or data characteristics. The IED attributes include: switchgear type, interval number, voltage level, remote control point information and analog quantity information, thereby completing the IED attribute settings corresponding to all switchgear.

S22 screens and filters the IED attributes according to the attribute classification, removes redundant data, completes IED creation, and obtains the switch device attribute information, including: switch device name, switch device type, bay name, remote control point information, and analog quantity information.

Then all data are stored according to attribute classification and used as the data source for the future. The remaining redundant data are filtered and not retained in the database.

Furthermore, in this embodiment, in step S22, redundant data is removed including the interval number and the manufacturer's identification, and when performing relevant parameter configuration, only the communication parameters involved in the one-button sequential control are extracted according to the IED attributes, and the relevant parameters of the redundant data are no longer obtained.

The present invention makes reasonable attribute definitions for the SCD model file in the early stage, obtains and classifies configuration information in a targeted manner according to the attributes when extracting configuration information, and after filtering unnecessary data, can significantly improve the automation of data configuration work, thereby realizing one-key sequential control automatic verification.

By classifying SCD file attributes in advance and filtering effective information, useless data information can be reduced and the efficiency of database data utilization can be improved.

Existing technologies often use the SCD model file as a whole for modeling and use. The information is comprehensive but the data volume is large. A lot of information is not used in the one-click sequential control verification summary. In the subsequent data configuration work, whether it is manual or automatic configuration, useless redundant data will increase the workload.

The present invention adopts advance attribute classification, filters invalid information in advance based on previous work experience, and only retains the switch equipment information and interval information involved in the one-key sequential control process, thereby greatly reducing the subsequent data volume, reducing the workload for subsequent automatic configuration and manual correction, and improving efficiency.

In step S2, in this embodiment, in combination with the interval characteristics of the substation primary wiring diagram and the main wiring diagram, according to the switch topology information and switch device attributes obtained by parsing, topology nodes are constructed, node information is improved, and a substation switch topology diagram is constructed, as shown in FIG3, including:

S2-1 determines the measurement and control equipment corresponding to the substation interval where the current switch device is located according to the primary equipment information table, uses the measurement and control equipment number as the keyword, matches it with the interval number in the IED attribute, and obtains the corresponding switch device attribute information node, including: switch device name, switch device type, interval analog quantity, and remote control point information.

The conventional method is to use the configuration tool to parse the SCD file through the program, extract information from key frames and keywords according to the naming rules, create IED, and configure related parameters.

In the present invention, when extracting information, the naming rules are followed, and the IED attributes are determined by keywords or data characteristics. According to the IED attributes, the information is screened and classified, and redundant data such as interval numbers and manufacturer identifications are removed in advance to complete the IED creation. When configuring related parameters, only the communication parameters involved in the one-key sequential control are extracted according to the IED attributes, and the related parameters of the redundant data are no longer obtained.

S2-2 combines the content of the one-key sequential control background operation ticket to determine other characteristic quantities involved in the above nodes, and configures the logical relationship between the node information to obtain the node composition of the switch topology diagram.

Since the IED information has been filtered at this time, combined with the Chinese device name in the device information table, the corresponding switch device name, switch device type, interval analog quantity, remote control point information and other nodes can be quickly read and matched to form important information.

Then, based on the interval characteristics and the contents of the sequential control operation ticket, determine other characteristic quantities involved in the node, such as analog quantity, pressure plate status, five-protection logic signals, etc., and configure the logical relationship between the node information. For example, the analog quantity change logic when the remote control point changes, the pressure plate status conditions when the remote control point changes, etc. It should be noted that this analog quantity change logic configuration is configured for some manufacturers' sequential control hosts to use analog quantity changes as one of the sequential control verification conditions. In actual testing, it does not represent the real-time analog quantity value of the actual on-site power system. Other characteristic values such as pressure plate status, five-protection logic, etc. can also follow this mode.

S2-3 completes the above node composition, and combines the main wiring diagram of the primary equipment to establish the switch topology diagram of all intervals in the entire substation. The switch topology diagram has a communication function. After receiving the switch position change signal, when the remote control point value and/or graph changes, the other characteristic quantities change according to the pre-configured logic.

Further, as shown in FIG4 , in this embodiment, step S2-1 includes the following steps:

S2-1-1 matches the measurement and control equipment information obtained by parsing in the SCD model file based on the Chinese name in the primary equipment information table to confirm the correspondence between the interval and the measurement and control equipment.

S2-1-2 uses the measurement and control equipment number as the keyword to filter the relevant IED attribute information, and combines the Chinese name in the primary equipment information table to obtain the switch device name, switch device type, interval analog quantity and remote control point information.

The remote control point information and switchgear described in S2-1-3 should correspond one to one. The corresponding relationship change logic between analog quantity and remote control point information can be pre-configured. This analog quantity change logic configuration is configured for some manufacturers' sequential control hosts to use analog quantity changes as one of the sequential control verification conditions. It does not represent the real-time analog quantity value of the actual on-site power system during actual testing. Other characteristic values such as pressure plate status, five-protection logic, etc. can also follow this mode.

S3 constructs a switch device model based on the switch device attribute information. The switch device model itself has a communication module, which remotely controls the received command, identifies the analog information and feeds back the comparison result between the remote control point and the analog information; and displays the real-time status of each switch device model on the switch topology diagram according to the corresponding interval for change verification.

In this embodiment, the switch device model includes the switch device name, switch device type, remote control action point information value in the SCD file, interval name, and analog quantity in the interval. Since the data has been filtered before, this step can be completed automatically by the program. The switch device model itself has a communication module, which can perform standard 61850 communication, and can perform remote control point and analog quantity information recognition on the received command and feedback the comparison result of the remote control point and analog quantity information.

For the completed switch device models, they are automatically matched with the switch topology diagram according to the corresponding intervals. The real-time status of each switch device model is displayed on the switch topology diagram according to the corresponding intervals. At this time, the switch position change verification can be performed. The switch device model receives the remote control command, and the switch position changes. The remote control point information of the device model and the analog quantity information are first verified. After the verification is completed, the result is fed back and the switch position is changed. The topology diagram receives the verification result and changes according to the current status of the switch position. Batch tasks can be set for switch position change verification, and the program runs automatically. For all switch device models that have been configured, the switch position change verification is performed one by one, and the result of each switch change and the action completion time are recorded to facilitate subsequent inquiries. As shown in Figure 5, it specifically includes:

S31: If the switch device model receives the remote control command and the switch position is changed, the remote control point information and analog quantity information in the switch device model are first verified, and the result is fed back after the verification is completed;

After receiving the switch position change signal, the switch model must be able to normally feedback the signal reception status and its own switch point changes. When the switch topology diagram is associated, the switch topology diagram can correctly feedback the interval switch status.

S32: the switch topology receives the verification result and changes according to the current state of the switch position;

S33 performs switch position change verification one by one for all switch device models that have been configured, and records the result and action completion time of each switch position change until all switch device models have completed the change verification.

In the embodiment of the present invention, the switch topology diagram is strictly associated with the switch device model, and changes in the characteristic quantities of the switch model will be directly reflected in the switch topology diagram. Such a design can accurately and effectively grasp the changes, thereby timely updating the attribute information of the switch, avoiding the need to check massive data during verification, and improving the efficiency of verification.

S4 matches and extracts the Chinese name in the one-key sequential control background operation ticket based on the substation interval information in the stored switch topology diagram, and generates a verification operation ticket according to the key information configured in the operation ticket.

In an embodiment of the present invention, based on the stored substation interval information: interval name, interval type, measurement and control equipment name, voltage level, the Chinese name in the one-key sequential control background operation ticket is matched and extracted to obtain the key information of the operation ticket configuration, including the operation ticket name, operation ticket interval, operation ticket execution order, operation ticket involved equipment, and operation ticket steps. A verification operation ticket is generated based on the acquired information. Among them, the verification operation ticket information strictly corresponds to the configuration content extracted from the SCD model file, including the measurement and control equipment name, the starting switch position, the switch position in the step, the analog quantity information, the name of the corresponding interval and the type of switch equipment.

Specifically, the bay name is determined through the substation bay information. The bay name (generally a Chinese name plus a number combining English and numbers) is used as a keyword to match the one-key sequential control background operation ticket.

The switch names involved in the one-key sequential control background operation ticket are always added on the basis of the interval English name. For example, the switches of interval 2M61 are 2M611, 2M613, 2M614, 2M615, etc. The operation ticket involved in the interval is determined by matching the English name, so as to extract the corresponding information.

According to the equipment names (names with letters and numbers) involved in the matched operation ticket that conform to the electrical name rules, key configuration information such as the interval involved in the operation ticket, the operation ticket name, the switch equipment and actions involved in each step, etc. are determined.

In this embodiment, as shown in FIG6 , it specifically includes:

S41 obtains corresponding power station bay attribute information according to the switch topology diagram, including: bay name, bay type, measurement and control equipment name and voltage level;

Determine the bay name through the substation bay information. Use the bay name (usually a Chinese name plus an English and digital number) as a keyword to match the one-key sequential control background operation ticket.

S42 obtains key configuration information of the operation ticket from the Chinese name of the one-key sequential control background operation ticket, including: the name of the operation ticket, the interval of the operation ticket, the execution order of the operation ticket, the equipment involved in the operation ticket and the steps of the operation ticket;

Because the switch names involved in the one-key sequential control background operation ticket are always added on the basis of the interval English name, for example, the switches of the 2M61 interval are 2M611, 2M613, 2M614, 2M615, etc. By matching the English name, the operation ticket involved in the interval is determined, and the corresponding information is extracted.

According to the equipment names (names with letters and numbers) involved in the matched operation ticket that conform to the electrical name rules, key configuration information such as the interval involved in the operation ticket, the operation ticket name, the switch equipment and actions involved in each step, etc. are determined.

S43 obtains a verification operation ticket based on the interval attribute information, key information of the operation ticket configuration, and current switch attribute information. The information of the verification operation ticket is no less than the name of the measurement and control equipment, the starting switch position, the switch position in the step, the analog quantity information, the name of the interval to which it belongs, and the type of switch equipment.

S5 uses the current switch state of the switch device model and the switch topology diagram to execute the verification operation ticket to complete the one-key sequential control automatic verification.

In this embodiment, the one-button sequential control is automatically verified to verify that the operation ticket information is strictly associated with the switch device model and the switch topology diagram. During the operation ticket verification, the operation ticket name, operation ticket interval, operation ticket execution order, operation ticket involved equipment, operation ticket steps, switch device model remote control point, analog quantity, switch status, and switch topology display in the operation ticket must all remain consistent.

Furthermore, the verification of the present invention includes forward verification and reverse verification, i.e., pre-verification and on-site verification, which verifies that the test system itself can correctly feedback when the sequence control command configuration conforms to the remote control point of the on-site SCD model file, and can correctly report errors when it does not conform to the remote control point of the SCD model file, thereby ensuring the correctness of the test system itself and the reliability of the communication function.

Specifically, in the present embodiment, step S5 specifically includes pre-verification, through the system built-in simulation sequence control host, according to the one-key sequence control background operation ticket, send the sequence control command. The one-key sequence control automatic verification module receives the command, performs remote control point comparison, returns the remote control result according to the comparison result, and modifies the switch position state. The switch topology map node changes accordingly according to the switch position change and displays it in real time. The analog quantity in the topology map changes accordingly according to the preset logic. The simulation sequence control host judges the result of the sequence control step based on the returned remote control result and the change of the analog quantity, and proceeds to the next step or terminates the error report. Complete the self-verification of all operation tickets, thereby ensuring the correctness and feasibility of each node of the configured topology map, the switch equipment model, the verification operation ticket, and the automatic verification part. Actual verification in the field environment can save a lot of debugging time.

The simulated sequence control host in the present invention is an independent system and can be integrated with the one-button sequence control test system in the same device. No additional equipment connection is required during pre-testing. When the test conditions cannot be provided on site, the configuration data of the one-button sequence control test module can be pre-tested in advance.

Specifically, in this embodiment, as shown in FIG7 , the method corresponding to the pre-verification includes the following steps:

The built-in analog sequential control host of S51 reuses the switch equipment characteristics and data extracted when constructing the switch topology diagram, and stores them in the database of the analog sequential control host. The switch equipment characteristics and data include: substation interval name, interval type, measurement and control equipment name, switch equipment name, switch equipment type, interval simulation, remote control point information, other characteristics and change logic.

The simulated sequential control host has its own database configuration, and can also perform project backup when necessary. Each project backup can be regarded as a sequential control host of a different substation.

S52 The simulated sequence control host is directly connected to the actual sequence control host, and the sequence control host issues a sequence control command. When the one-key sequence control command starts, the simulated sequence control host resets the initial position of the switch position according to the requirements of the verification operation ticket.

After the S53 command is issued, the analog sequential control host receives the command, performs remote control point comparison, returns the remote control result according to the comparison result, and modifies the switch position state;

S54: the simulated sequence control host receives the remote control result, modifies the remote control point value in the database of the simulated sequence control host, and changes the other characteristic quantities according to the preset logic, and the corresponding switch topology diagram is also modified and changed accordingly according to the remote control result;

The analog sequence control host in S55 determines the result of the one-key sequence control step according to the returned remote control result and the change of the analog quantity, and then proceeds to the next step or terminates with an error.

Furthermore, in this embodiment, step S5 also includes on-site verification. During on-site verification, the simulated sequence control host and the one-key sequence control automatic verification module are temporarily disconnected from the communication connection, and the automatic verification module receives the actual sequence control host command instead. The verification operation ticket is executed to perform the one-key sequence control automatic verification.

First, the current switch state of the switch device model is verified, and the switch topology is synchronized according to the initial switch position. In the subsequent verification steps, the switch device model is strictly associated with the switch topology, and the switch topology reflects the current state of the switch model in real time.

Verify step by step according to the steps of the verification operation ticket, simulate the sequence control host to issue a sequence control command, match the remote control point information involved in the sequence control command with the information in the verification operation ticket, and if the match is successful, the switch position in the switch device model will change, and the switch topology diagram will change.

After completing a single step, the interval analog quantity is calibrated. If it is within the normal range, the next step is to proceed to the initial position calibration.

The verification operation ticket information, switch equipment model communication content, and switch topology changes involved in the automatic verification process are all automatically recorded. After all steps are completed, a verification report is generated based on the automatically recorded information and combined with the switch position verification record. The report is automatically stored and archived for subsequent inquiries.

As shown in Figure 8, the on-site verification specifically includes the following steps:

S5-1 verifies the current switch state of the switch device model and synchronizes the switch topology diagram according to the initial switch position;

S5-2 In the subsequent verification step, the switch device model is associated with the switch topology map in real time, and the switch topology map reflects the current state of the switch model in real time;

S5-3 checks step by step according to the steps of the verification operation ticket, the simulated sequential control host sends a sequential control command, matches the remote control point information involved in the sequential control command with the remote control point information in the verification operation ticket, and if the match is successful, the switch position in the switch device model changes, and the switch topology diagram changes; the matching success standard is the same Chinese name of the switch device, the measurement and control device number and the configured remote control point information value;

After completing a single step, S5-4 verifies the interval analog quantity. If it is within the normal range, it proceeds to the next step of initial position verification.

In summary, as shown in FIG9 , the method mainly involves an SCD model file, which includes an IED attribute classification and a Chinese name, and deletes parameters such as the manufacturer identification, model number, and interval number in the IED attribute classification, obtains the switch device attributes from the IED attribute classification, and constructs a switch device model from the switch device attributes. The switch topology diagram is obtained from the Chinese name mentioned above, the switch position change is checked from the switch topology diagram and the switch device model, the verification operation ticket is obtained from the Chinese name, the switch device model, the switch topology diagram, and the verification operation ticket are automatically checked for one-button sequential control, and a verification report is generated based on the automatic position change check and the one-button sequential control automatic check.
