Rapid Generation of Transient Stability Emergency Control Strategy Based on Feature Matching
摘要
Abstract
The emergency control mode of"online calculation and real-time matching"is an effective way and a technological development trend to reduce the risk of control strategy mismatching.To further improve the rapidity of online emergency control strategy generation,a rapid generation method of transient stability emergency control strategy based on feature matching is proposed.With the help of the quantitative analysis ability of the extended equal-area criterion for transient stability and the time-varying degree of the locus under the power grid fault,the matching indexes of the characteristic quantities of the operation mode are established by comprehensively considering the transient stability locus feature of the power grid and key characteristic quantities of the steady-state power flow.Then,the most similar mode can be matched in the historical modes to realize the rapid generation of the emergency control strategy,and the strategy is then distributed to the devices for execution after verification.Finally,the effectiveness of the proposed method is verified based on the actual power grid.关键词
