基于广域测量系统的暂态失稳判别方法适应性研究
Adaptability Study on Wide Area Measurement System Based Transient Instability Detection Methods
摘要
Abstract
With consideration of the wide application of phasor measurement unit ( PMU ) and wide area measurement system ( WAMS) in power system, the disturbed track pattern of the power system is analyzed. By studying the WAMS based transient stabil-ity detection technology, the principles and characteristics of several detection methods are studied including status threshold value de-tection, concave and convex trajectory of phase detection, generator energy function detection, and measured trajectory based extended equal area criteria ( EEAC) detection. Based on a practical system with actual 2012 CSG heavy load mode data, simulation analysis is carried out on accuracy, speediness and measurement requirements of these detection methods, the merits and faults and applicability of these detection methods are compared to provide reference for engineering application.关键词
