一种基于本地信息的自适应过负荷保护方案
Self-adaptive Overload Protection Scheme Based on Local Information
摘要
Abstract
Intertripping caused by flow transferring is an important factor to result in blackout in various countries. Taking result of overload recognition of flow transferring as triggering event,a kind of self-adaptive overload protection scheme based on local information was proposed. According to states of overloads on different lines,different measures were taken. For faults in protection zones,the backup protection should rapidly isolate the breaker tripping after time-delay finished. For overload caused by flow transferring,by measuring data evaluation line which could meet real-time requirement,it was able to bear the maximum capacity of overload,modify action time setting value of backup protection and buy time for secu-ring and stabilizing the control system. Simulation results verified effectiveness of this scheme.关键词
