一起死区故障导致35 kV母差保护动作案例分析

Analysis of a Case of 35 kV Bus Differential Protection Action Caused by a Deadband Fault

    摘要
  • 摘要: 介绍了在AVC切除电抗器过程中，发生的一起35 kV母差保护动作事件，导致35 kVⅡ段母线上所有开关全部跳闸。根据现场采集情况，分析了开关跳闸原因，同时对预控措施做了阐述。

     

    Abstract: This article introduces a 35 kV bus differential protection action event that occurred during the AVC reactor removal process. Causing all switches on the 35 kVⅡ section bus to trip. Based on on-site collection, the cause of switch tripping was analyzed, and the pre control measures were stated.
