Abstract
介绍了广域继电保护的几种结构形式,并着重对变电站集中式和区域集中式在故障识别算法、跳闸策略、信息冗余等关键技术上的研究现状进行综述,分析了两种结构在通讯范围、通讯量、算法复杂程度和可靠性等方面的优缺点。阐述了继电保护与安稳保护协调发展的需求,并对广域继电保护下一步研究进行展望。 First, several system structures for wide-area relaying protection (WARP) are presented. Aimed at station centralize structure and regional centralized structure, research status for related key techniques is reviewed, including fault identification algorithm, tripping strategy, information redundancy, etc. Afterwards, advantage and disadvantage of two different structures on commu-nication range, communication traffic, algorithm complexity and reliability are analyzed. In the end, needs for coordination development between WARP and Wide-Area System Protection (WASP) are discussed and further research for WARP is prospected.
