摘要
广域测量系统WAMS(Wide Area Measurement System)主要源自电力系统时间上同步和空间上广域的要求,利用全球定位系统GPS(GlobalPositionSystem)时钟同步,进行广域电力系统状态测量。回顾了国内外WAMS的发展概况,介绍了WAMS的结构,对现有功角和相量测量原理进行了比较,最后论述其同步故障录波、引入状态估计、功角监视等应用功能及发展趋势。
WAMS(Wide Area Measurement System) is developed to meet the requirements of synchro-nization in time and wide area in space. With the application of GPS(Global Position System),the state measurement in the same time will be possible. The study on WAMS is reviewed. The struc-tures of WAMS are introduced,the principles of angle measurement and phase measurement are compared. Some application functions,such as fault recording,state estimation and angle monitoring,are discussed. Finally the study is foreseen. This project is supported by Excellent Young Teachers Program of MOE,P.R.China([2001]182).
