Adaptive voltage regulator design for static VAR systems

The performance of a static VAR system (SVS) strongly depends on the operat ing conditions of the power system at which the SVS is connected. Since the se operating conditions often vary unpredictably, limitations to the perfor mance of a SVS may be derived. To overcome such drawbacks, a new SVS voltag e regulation scheme based on the adaptive control theory is proposed. The d esign of the adaptive voltage regulator is described in detail. The results obtained by numerical simulations show the effectiveness of the proposed c ontrol scheme. (C) 2001 Elsevier Science Ltd. All rights reserved.
