    Abstract

    This paper presents an innovative approach to apply wide-area control actions in real-time and prevent emerging instability. A software platform has been further developed, which utilizes Real Time Digital Simulator (RTDS) technology to prevent scenarios leading to power system instability. The software platform receives phasor measurement unit (PMU) data at a high repetition rate for full system observability. The PMU data serves as input for methods capable of analyzing the steady state torque balance for each individual generator and to determine available power reserves and possible remedial actions. The capabilities of the software platform were demonstrated by testing the methods on the Nordic32 test system and the results show that the methods can determine an active power re-dispatch and apply the countermeasures in realtime and prevent aperiodic rotor angle instability.
