摘要
目前电网规模越来越大,运行方式越来越复杂,熟悉高压输电线路的保护原理和配置对运行人员处理变电站异常信号非常重要。本文通过对常见线路的保护原理阐述和一起典型220k V线路保护装置异常的分析处理,为电力人员评估保护故障对电网运行方式的影响和处理提供借鉴。
With the increasing volume of grid scale and more complex operation mode, operators are required to have a good knowledge of principles and specific configuration of high-voltage power line protection in order to handle the abnormal situations in electrical substations. Based on the principles of the common line protection, a typical abnormal situation of line protection equipment is analyzed and handled, which serves as a reference for electricity workers to know about how to assess the impact caused by abnormal signals and how to handle abnormal situations.
