摘要
针对目前系统主站在电网发生故障时收到大量未经筛选的继电保护设备运行信息,有效信息少的缺点,从工程实际应用角度出发,提出了一种实用的基于关键字的输电线路故障信息筛选方法,剔除与输电线路故障无关的信息,提取有效的故障信息,并在此基础上,设计实现了一套基于保信系统的输电线路故障定位系统,为故障巡线工作提供时效性更强的参考。
Master-station receives massive unselected fault information during the power grid faults and few parts of the information are useful. Thus,from engineering application perspective,a practical method for the selection of transmission line fault information based on key words is proposed in this paper. This method can eliminate the information that is not related to the fault of transmission line and extract effective fault information. Meanwhile,a transmission line fault location system based on fault information processing system has been designed and developed to provide guidance for transmission line inspection with better timeliness.
