Transient Stability Assessment of power systems through Wide-Area Monitoring System

Real-time transient stability assessment is becoming more feasible using synchrophasor systems. Modern Wide-Area Monitoring Systems (WAMS) are equipped with PMUs and fast communication infrastructure. The paramount advantage of modern WAMS is their capability to provide fast, reliable and synchronized real-time measurements of different system parameters. In this paper, a new real-time Transmission Stability Assessment (TSA) technique is proposed. In the proposed technique, angle-based indices are applied to train five consecutive Decision Trees (DTs) which are used for real-time TSA. The proposed technique is tested on the Northern Intertie, connecting BC Hydro and Bonneville Power Administration (BPA) systems. The obtained results validate the efficiency of the proposed scheme.
