Definitions

  • the present invention relates generally to electrical power distribution and management and, in particular, to an electrical outlet, or other device associated with a local (e.g., single or multiple residential or business premises) circuit, to intelligently monitor at least a portion of the circuit and control delivery of electricity over the circuit.
  • a local e.g., single or multiple residential or business premises
  • Power distribution and electrical distribution are monitored and controlled for a variety of purposes.
  • power distribution generally refers to transmission between a power plant and substations whereas electrical distribution refers to delivery from a substation to consumers. Electricity is further distributed within consumer premises typically via a number of local circuits.
  • Power distribution may be monitored and controlled in relation to addressing actual or potential over capacity conditions. Such conditions have become increasingly common in the United States and elsewhere due to increasing industrial and residential power needs coupled with aging power infrastructure and practical limitations on new power generation. Over capacity conditions are often addressed by reducing or interrupting power provided to standard residential and commercial consumers, e.g., blackouts or brownouts. For example, during periods of peak usage, a rolling blackout may be implemented where power to grid subdivisions is sequentially interrupted to reduce the overall load on the grid.
  • fuses, circuit breakers, ground fault indicators, surge protectors and the like are generally employed to interrupt or damp electricity on a circuit in the event that the current drawn by the circuit exceeds a prescribed level.
  • These elements are typically required by code and may be customized to some extent, for example, with respect to circuits for supplying high (e.g. dryers, air conditioners) or low (e.g., lighting) power devices.
  • high e.g. dryers, air conditioners
  • low e.g., lighting
  • these elements are generally unintelligent and limited to hazard avoidance. They typically do not recognize devices or device types when connected to a circuit, do not allow for addressing larger grid needs and are not sufficiently responsive for addressing certain safety issues such as potential electrocutions.
  • the present invention relates to intelligent circuit devices such as electrical outlets, e.g., standard NEMA outlets, and to customer premises electrical systems, appliances, power distribution systems and associated processes that may utilize such smart circuit devices.
  • the smart circuit devices of the present invention can monitor a load connected to a circuit and control distribution of power via the circuit.
  • the circuit devices can also be controlled via a communications interface so as to implement a local or grid policy concerning electrical delivery or usage. In this manner, power can be distributed more efficiently, outlet and building wiring safety can be enhanced and electrical grid capacity problems can be addressed more effectively. Also, the invention delivers security and convenience features.
  • a utility (including a system and associated functionality) for enabling Transmission Control Protocol/Internet Protocol (TCP/IP) communication to an outlet receptacle, e.g., a standard NEMA outlet receptacle.
  • TCP/IP Transmission Control Protocol/Internet Protocol
  • the receptacle effectively becomes a client or data network node.
  • the outlet receptacles can operate as intelligent control points for electrical distribution, providing feedback concerning the types of devices that are currently plugged into the receptacles and selectively controlling the delivery of electricity via the receptacles (including reducing power consumption by eliminating individual power waveform cycles delivered via the receptacles via fast on/off switching).
  • the receptacles can be controlled via a wide area network using TCP/IP communications so as to enable remote or intelligent operation of devices that are not otherwise adapted for data network control.
  • TCP/IP outlet technology also provides a convenient mechanism for intelligent devices to communicate via power lines to a wide area network and facilitates standardization of such devices.
  • TCP/IP has a number of advantages including the following:
  • TCP/IP is the preferred protocol for communicating to the receptacles for both technical and economic reasons.
  • TCP/IP is the standard protocol on the internet, the largest network on the planet. It is an open protocol and very unlikely to be replaced.
  • TCP implementations and supporting infrastructure continue to improve.
  • a utility for controlling delivery of power via a local (e.g., on-premises) circuit device such as a receptacle or group of receptacles based on a load analysis.
  • the utility involves monitoring at least one local circuit device to determine information regarding a loading of the local circuit device based on an analysis (e.g., digital processing) of an electrical signal transmitted via the circuit device, and controlling delivery of power via the circuit device based on the analysis.
  • the analysis may be implemented by a digital processor at the circuit device such as at an outlet or at another location (e.g., at a circuit breaker panel or elsewhere on a controlled circuit).
  • the electrical signal can be analyzed to determine a classification of an electrical device, e.g., to identify the specific electrical device or the type of electrical device (or an intelligent device can identify itself), to identify power delivery quality issues (in either the power supplied or the electrical wiring), to provide virtual GFCI functionality in specified receptacles as needed by comparing summary current measurements to neutral current, or to identify a loading anomaly or safety issue.
  • a classification of an electrical device e.g., to identify the specific electrical device or the type of electrical device (or an intelligent device can identify itself
  • power delivery quality issues in either the power supplied or the electrical wiring
  • virtual GFCI functionality in specified receptacles as needed by comparing summary current measurements to neutral current, or to identify a loading anomaly or safety issue.
  • This information may be used to, for example, reduce the power delivered to the device (e.g., via rapid switching to eliminate selected cycles of the power signal or by interrupting power to the device for a given time period(s)) or to assign the device/receptacle a priority level in the event of power reduction (e.g., a brownout).
  • the digital analysis may indicate a short circuit, a potential shock or electrocution event or other safety concern. In such cases, power to the receptacle may be interrupted. Also, if a device switch is not supposed to be on, e.g., if the resident is on vacation and a light is suddenly turned on, a security alert can be generated as well as an email alert.
  • a fast power switching function can be implemented to control power delivery.
  • Such fast switching structure can be used in at least two ways: 1) arc suppression when turning on/off main relays; and 2) fast switching when “stealing” cycles.

  • the communications between the local controller 650 and the receptacles 612 , 634 and 644 may be conducted via the power lines, wirelessly in accordance with an IEEE 802.11 protocol or in any other appropriate fashion. It will be appreciated that customized messaging may be provided in this regard to accomplish the purposes of the system 600 .
  • the processor 655 can function as a protocol gateway to translate between the protocol for communications between the remote controller 670 and the local controller 650 and the protocol used for internal messaging between the local controller 650 and the receptacles 612 , 634 and 644 .
  • Devices can be plugged into the smart receptacles and use the controller as a gateway to the data center LAN (instead of or in addition to the WAN).
  • each of the output ports 654 of the local controller 650 may be associated with a power wire communications interface 651 - 653 .
  • These interfaces 651 - 653 are operative to induce messaging signals in the power lines as well as to remove incoming messaging signals from the power lines so as to provide effective electrical isolation of the different communication pathways.
  • Similar power line messaging interfaces 611 , 631 - 633 and 641 - 643 are provided in connection with the power strips 610 , 630 and 640 for the same reasons.
  • Each individual receptacle of a power strip may be controlled independently or all receptacles of a power strip may be controlled as a group in accordance with the present invention.
  • all of the receptacles 612 of the strip 610 are associated with a single communications interface 611 .
  • all of the receptacles 612 of the strip 610 may be associated with a common logical element for monitoring electrical signatures or receiving messages from the devices 601 - 603 .
  • each receptacle 634 and 644 of the power strips 630 and 640 is associated with its own independent communications interface 631 - 633 and 641 - 643 in the illustrated embodiment.
  • each receptacle 634 and 644 may have dedicated wiring or the signals transmitted through the power wiring may be multiplexed with respect to the individual receptacles (e.g., time division multiplexed, frequency division multiplexed, code-division multiplexed, etc.).
  • the devices 604 - 609 associated with the receptacles 634 and 644 can be individually controlled, and the devices 604 - 609 can independently message the local controller 650 and intern, in turn, the remote controller 670 .
  • FIG. 8 shows a control system 800 for a set of receptacles defining a controlled domain.
  • the receptacles may include a number of receptacle outlets 802 (typical for home or business environments) and/or a number of plug strips 805 or adaptors (typical for data center environments) that may be arranged in one or more branch circuits 806 .
  • the receptacles are controlled by a local controller 808 , which may be, for example, embodied in a personal computer (typical for home or business applications) or in a single board computer incorporated into a power distribution unit of a data center.
  • the local controller uses a transceiver 810 to insert signals into the main 812 and branch circuits 806 for communication to the receptacles and to receive signals from the receptacles.
  • a signal isolation device 814 which may be a signal canceller or a signal attenuator as described above, substantially prevents transmission of these signals to external (outside of the controlled domain) power lines 816 . This structure may be replicated for A and B power sources in a data center.
  • FIG. 7 illustrates a process 700 that may be implemented in connection with operation of the present invention in the data center context.
  • the process 700 is initiated by establishing ( 702 ) rules for devices or classes of devices. For example, these rules may define preferences for powering up or powering down devices, establish groups of devices to be controlled collectively, determine who may access devices and at what times, etc.
  • the process 700 further involves developing ( 704 ) a map of output/outlet pairings. In this regard, it is possible to identify devices or classes of devices based on a signature analysis as described above. Alternatively, a data center user may define what devices are connected to what receptacles of what power strips and what power strips are attached to what outlet ports of the power distribution units.
  • the user can define groups of devices that will be operated collectively (e.g., by plugging the devices into a power strip that is operated as a unit) and can specify critical devices for fail-safe operation. Such operation can then be executed simply by plugging the devices into the correct outlets of the correct power strips and plugging the power strips into the correct output ports of the power distribution unit. Execution of this power structuring may be facilitated by way of appropriate indicators, such as LEDs or small display units provided on the power strips and/or the power distribution unit. In this manner, the devices can be easily plugged ( 706 ) into appropriate outlets.
  • the power strips or the individual receptacles then receive ( 708 ) an input from the device or the local or remote controller.
  • an operator of a remote controller unit may choose to power down or power up a device or set of devices.
  • An appropriate message is transmitted from the remote controller to the local controller, and this is in turn communicated from the local controller to the power strip or receptacle via the power wiring as discussed above.
  • a signal such as a power signal for signature analysis or a sensor output signal, may be received at the receptacle from one of the devices and communicated to the local controller (and, if appropriate, to the remote controller). Any such input is then processed ( 710 ) using the noted map and appropriate rules.
  • an instruction from a remote controller to power down certain devices can be executed by consulting the map to identify the outlets associated with the appropriate devices and then communicating a power down signal to those receptacles.
  • a signal from a device such as a sensor may be interpreted by consulting the map to determine what sensor transmitted the signal and then accessing and applying the appropriate rules for processing the signal.
  • the current interrupting ability of the receptacle described above permits using an additional bifilar wound transformer for sensing unbalanced current in the load and interrupting the power delivery to the load in certain conditions.
  • This feature is generally similar to common ground fault circuit interruption (GFCI) devices. It differs in that it utilizes the general purpose disconnect relay for the actual disconnection means in the event a Unbalanced current condition exists. It also differs in that the detection and decision to disconnect is not performed in the same way as a traditional GFCI, in that the microprocessor control used for the signature detection also has the ability to analyze the current sense data from the bifilar wound transformer and in doing so can filter out unwanted or alias current transients.
  • GFCI common ground fault circuit interruption
  • an additional bifilar wound transformer 902 is added in the current path, similar to traditional GFCI, and the sensed current “differential” is amplified by the high gain differential amplifier 901 .
  • the signal is presented to the Sense and Control Module 903 where a 4 bit ladder analog to digital (A to D) converter converts the incoming analog signal to a digital signal.
  • a to D 4 bit ladder analog to digital
  • the data is processed on an interrupt basis in the microprocessor. If any data appears at the output of the ladder A to D, the processor stops what it is doing and begins analysis of the incoming data stream from the GFCI sense transformer. At this point signature analysis algorithms similar to the algorithms used for general current load analysis are applied to the incoming data.
  • the power control relays 940 , 950 are energized, thus in turn disconnecting the AC power source from each of the load receptacles 907 , 908 . Since the current sense is in the primary power path, both relays must be energized.
  • the vent is recorded temporarily in the sense and control module 903 and sent to the Central Command Processor via the current transmitter 909 .
  • the vent data is also forwarded to the central command processor for additional analysis.
  • the Central Command Processor can determine if the event data was false or true and act accordingly, or it can wait for user intervention and submit a reset. At any time, either the Central Command Processor, or a local user can reset the GFCI interruption condition. This can be accomplished by either receiving a command from the Central Command Processor via the Current Receive Modulator 909 or from manualreset button on the receptacle 906 by direct user intervention.
  • Power can be momentarily restored to one receptacle at a time. If the GFCI event still exists, a determination can be made which receptacle is responsible at this time, and the associated LED 910 or 911 can be illuminated and/or flashed.
  • LEDs 910 , 911 allow other useful functions to be included in the Zonit Smart Receptacle.
  • These LEIS 910 , 911 can be controlled from the Central Command Processor.
  • User interface there can initiate several functions using the LEDs 910 , 911 located adjacent to each of the receptacles 907 , 908 .
  • Some of the functions include, but are not limited to:
  • the LEDs 910 , 911 are connected to the Sense and Control Module 903 . It receives information either locally from the current sense coils in the relays 940 , 950 from the Current Sense Transformer 902 , the local manual reset button 906 , or from the Central Command Processor via the Current Receive Modulator 909 . The various information associated with the LED functions is analyzed by the Sense: and Control module and the appropriate LED 910 and 911 is illuminated or extinguished as needed.
  • the LEDs 910 , 911 are high illumination types, as much as 1 watt each.
  • the Sense and control Module 903 can pulse width modulate the power to the LEDS 910 , 911 to provide a low level output of light. An “indicator light” level of output. For Night Light operation, a higher level of output can be initiated, as much as a continuous on state (no modulation).
