Abstract:
Protective IEDs in an electrical power system, such as distributed controllers, may periodically or in real-time communicate updated protection settings to a wide-area controller, such as a coordination controller, that defines and/or implements a remedial action scheme to protect the electrical power system. The wide-area controller may utilize real-time protection setting information from a plurality of protective IEDs to perform dynamic transient model simulations based on (1) the current topology of the power system, (2) real-time measurements from the system, and (3) the updated, real-time protection settings of various IEDs within the system. The results of the updated transient model simulations may be used to dynamically adjust the remedial actions scheme of the wide-area controller.
