基于趋势分析的电力系统态势感知方法
A novel situational awareness method based on trend analysis of power system
摘要
Abstract
Situational awareness plays a main role in the power security defense system.Aiming at the problem that the current power system situational awareness method cannot describe the safety distance quantitatively and the evolution speed of the future system,a trend analysis-based power system situational awareness method is proposed in this paper.Based on trend analysis,a novel situational awareness framework is proposed.On the basis of information acquisition,the N-1 static safety distance model is introduced to evaluate the security level of the current and future state of the system.By combining the safety distance model with qualitative trend analysis,the moving direction and trend change rate of the oper-ating point in the future change state are automatically captured,so as to improve the ability of the system security situa-tional awareness.The application results of IEEE 118-bus system and actual power system show that the proposed method can effectively help system operators to monitor,predict and prevent potential problems.关键词
