And after all steps are finished, according to the automatic record information, the switch deflection check record is combined to generate a check report, and the report is automatically stored for reservation, so that the follow-up inquiry is convenient.
As shown in fig. 8, the field verification specifically includes the following steps:
S5-1, verifying the switching state of a current switching device model, and synchronizing a switching topological graph according to an initial switching position;
S5-2, in a later verification step, the switching equipment model is associated with a switching topological graph in real time, and the switching topological graph reflects the current state of the switching model in real time;
s5-3, gradually checking according to the step of verifying the operation ticket, wherein the simulation sequential control host machine sends out a sequential control command, and matching remote control point information related in the sequential control command with remote control point information in the verification operation ticket, if matching is successful, the switch position in a switch equipment model is changed, and the switch topology is changed;
S5-4, checking the interval analog quantity after finishing a single step, and if the interval analog quantity is within a normal range, entering the checking of the initial position of the next step.
In summary, as shown in fig. 9, the method mainly involves an SCD model file, where the SCD model file includes IED attribute classification and chinese name, and removes parameters such as manufacturer identification, model number and interval number in the IED attribute classification, obtains switchgear attribute from the IED attribute classification, and constructs a switchgear model from the switchgear attribute. Obtaining a switch topological graph from the Chinese names, checking the switch deflection from the switch topological graph and the switch equipment model, obtaining a verification operation ticket from the Chinese names, performing one-key sequential control automatic check on the switch equipment model, the switch topological graph and the verification operation ticket, and generating a verification report according to the automatic deflection check and the one-key sequential control automatic check. The verification operation ticket is obtained according to the Chinese name and the operation ticket data.
