Adaptive delaying is a relatively new subject. It proposes to provide protection functions that will adapt to changing power system conditions. Most relays do not have the ability to change relay settings rapidly enough to become adaptive candidates. Also, they do not have high-speed communication capability to collect local substation and remote substation information. The adaptive relay presented in this article recognizes power system changes and uses a modified system impedance matrix to change relay settings. Adaptive out-of-step relaying is one of the most promising adaptive relaying concepts. The Electric Power Research Institute (EPRI) contracted Virginia Tech to investigate a Florida-Georgia 500kV interconnection. This new technique may provide a robust power swing indication unavailable from static mho characteristic approaches.
