摘要
为解决电网监控调度快速事故处理,以告警窗的事件顺序记录信息为基础,引入了时序约束特性相关概念,充分考虑各种故障集下保护与断路器动作逻辑,构建各种电压等级下系统故障类型推理的有限状态机模型。以10kV配电系统事故案例对模型进行测试,证明模型能快速分析所在时间区间触发的保护动作事件,有效帮助运行调度员快速开展系统消缺和事故处理。
in order to solve the problem of fast fault handling in power grid monitoring and dispatching,based on the information of sequence of event in alarm window,this paper introduces the concept of time sequence constraint characteristics,fully considers the protection and breaker action logic under various fault sets,and constructs the finite state machine model of system fault type reasoning under various voltage levels.The 10 kV distribution system accident case is used to test the model,which proves that the model can quickly analyze the protection action events triggered by the time interval,and effectively help the operation dispatcher to quickly carry out system defect elimination and accident handling.
