Adaptive topology assisted protection and control of electric power delivery systems

摘要

Disclosed are adaptive communication assisted protection and control. Local intelligent electronic devices (IEDs) associated with local switching devices and having unique IDs may transmit switch status and unique IDs to an area IED. The area IED may calculate topology using switch status, and provide control information to local IEDs using the topology. The area IED may communicate the unique ID of the local IED calculated to be immediately upstream of each local IED and, upon detection of a fault, the local IEDs may send blocking signals that include the received unique ID of the IED immediately upstream therefrom. The area IED may communicate control commands that include the unique IDs and control commands for the local IEDs to take the control action. Upon matching of the unique ID in the control command with its own unique ID, the local IEDs may take the control action and transmit remaining actions.

1. A system for control of electric power delivery, comprising:
a plurality of switching devices for opening and closing at various locations on en electric power delivery system; a plurality of local intelligent electronic devices (IEDs), each local IED of the plurality of local IEDs:
in communication with one of the plurality of switching devices;comprising a unique ID;in communication with the electric power delivery system for obtaining electric power information therefrom; andcomprising a communication module for sending power system information and receiving command information; an area IED comprising:
a topology module for maintaining and updating a topology of the electric power delivery system;a communication module for receiving electric power system information from the local IEDs and transmitting to each local IED the unique ID of the local IED immediately upstream of the local IED; and, a communication network in communication with the communication modules of the area IED and each of the local IEDs;
wherein upon detection of a fault, each local IED that detected the fault transmits a blocking message that includes the unique ID of the IED immediately upstream therefrom; and,wherein each local IED blocks opening of its associated switching device upon receipt of a blocking message that includes its unique ID.
