Abstract

A system for real-time monitoring of synchrophasors from an electrical power system serving multiple geographic areas can control system instability, without preset parameters or thresholds, detects power flow between the generation sources. If a change in power flow of at least 5% over at time period of 1 second or less occurs and the response to the change in power flow is greater than the change in power flow a signal is generated for corrective action.
