Abstract
A system for determining channel delay or communication link asymmetry in an electric power system. The delay or asymmetry uses local clock signals instead of an external time source. Prediction errors are calculated using communications among the devices. A prediction algorithm compares the predicted channel delay against a measured channel delay. When the prediction error changes abruptly, the channel delay or communication asymmetry is detected.
