摘要：

This paper presents a fuzzy-expert system approach to steady-state voltage stability monitoring and control in a power system. In the proposed rule-based expert system, a systematic procedure for voltage stability monitoring and control is developed. Key elements associated with voltage instability are identified using modal analysis. The information from the above analysis is stored in a knowledge base. A set of decision rules relating key system variables to voltage stability are established. The designed expert system performs voltage stability monitoring and control through deductive reasoning. The New England 39-bus system is taken as a case study to illustrate the proposed procedure. (C) 1998 Elsevier Science S.A. All rights reserved.
