| Flexible AC Transmission Systems (FACTS) devices are playing an increasingly important role in electrical power systems. They have been used to enhance the power system stability and performance. A Static VAr Compensator (SVC), one of the first breed of FACTS devices, is a fast controllable generator and/or absorber of reactive power and can contribute to improve system performance in a number of areas.; This dissertation gives a survey of the prospective applications of SVC in power systems with particular emphasis on the use of SVC with supplementary adaptive controller to enhance system damping. The application areas are briefly outlined and the SVC is compared with other possible techniques. A relatively detailed description of the SVC, Recursive Least Squares (RLS) identification algorithm, Kalman Filter (KF) operating as parameters estimator algorithm and variable Pole-Shifting (PS) linear feedback control theory are given, supported by simulation studies to evaluate the SVC adaptive control performance. |
