Abstract

Abstract : This study presents results on a dynamic anti‐windup compensator (DAWC) for the flexible AC transmission system‐based wide‐area damping controller (WADC). A systematic design approach of the DAWC is proposed following a typical two‐step design procedure. First, a third‐order WADC is designed for a 10‐machine, 39‐bus power system reinforced with a static synchronous compensator to damp the critical inter‐area modes by employing appropriate global signal measurements. The full‐order DAWC design method is applied to improve the dynamic performance of the saturated WADC. The robustness of the DAWC can cover a wide range of the operating conditions. Comparative studies on static AW and DAWC have been carried out on both the numerical simulation and experimental platform. Both simulation and experimental results demonstrate the improved performances of the DAWC.
