| 摘 要： | 近年随着电网规模扩大、区域系统互联,电力系统出现一些现有方法难以解决的稳定问题,例如,如何持久有效地抑制区间低频振荡等,而同步相量测量技术的发展及广域测量系统(WAMS)的建设为此提供了新的手段.重点结合实际系统应用说明了当前世界上WAMS发展现状及其在电力系统保护与稳定控制中的应用实例.首先,介绍了PMU及WAMS的基本原理与历史发展过程;其次,在详细说明美国与中国WAMS发展现状的基础上,概述了各主要WAMS的规模和PMU的性能水平.最后,从非连续控制及连续反馈控制2个方面介绍了WAMS在电力系统稳定控制中的实际方案.

| Abstract: | After interconnections of regional grids,the extended power system demonstrates different characteristics in stability aspects.Some new problems can not be resolved effectively with the employment of traditional solutions,e.g.how to continuously suppress the inter-area low-frequency oscillations.However,alternative approaches can be designed based on synchronized phasor measurement techniques and wide area measurement system(WAMS).In this paper,current WAMS developments and the applications in power system ... |
