Dynamic Performance Evaluation of Excitation Control System Based on Intuitionistic Fuzzy Sets Strategy

Abstract:

To indicate excitation control system dynamic performances comprehensively and objectively, an excitation control system comprehensive evaluation method based on intuitionistic fuzzy sets and TOPSIS is presented. Evaluation indexes such as the conventional unit excitation output response lag time, excitation voltage rise speed, multiple field strong excitation, excitation control system transient gain, dynamic gain and static gain are mainly used. In the evaluation method, the intuitionistic fuzzy sets strategy is used to determine the index weight of excitation control system and the improved TOPSIS is used to calculate the comprehensive dynamic performance of excitation control system. The presented comprehensive evaluation method is verified by actual operation data of excitation control system of multiple generation sets, and the results show that the proposed evaluation method on the performances of excitation control systems of generating sets is effective and feasible.
