针对风电外送基地的暂态切机决策模型
A Transient Tripping Decision-Making Model for Sending-Out Wind Power System
摘要
Abstract
1 This paper focuses on coordinated tripping measures with sending-out wind power base participation. Based on analysis of transient characteristics of squirrel cage induction generator (SCIG), doubly-fed induction generator (DFIG) and direct-drive permanent magnet synchronous generator (DDPMG),different effects caused by tripping SCIG, DFIG and DDPMG on the first swing and recovery process of system oscillation, relating to system damping changes, are studied by defining transient energy tripping control index and system oscillation recovery index. Research shows that effects of tripping DFIG and DDPMG are similar but combined tripping of three different wind power generators should be considered. To coordinate both angle stability and recovery process of system oscillation after tripping, a bi-objective nonlinear weighted fuzzy tripping optimization model is proposed to determine optimal tripping combination of different wind power generators. Simulation results show that it improves characteristics of both first swing and subsequent system recovery process. It is a helpful guideline to enhance power system stability.关键词
