220 kV 变电站110 kV 母差保护改造施工方案

母差保护是电力系统继电保护的重要组成部分,母线故障是电力系统中非常严重的故障,它直接影响母线上所连接的所有设备的安全可靠运行,因此随着电力技术的快速发展,对母差保护的快速性、灵敏性、可靠性、选择性的要求也越来越高。文章以110kV母差保护改造工程为例,介绍了110kV母差保护更换的施工方案,阐述了施工过程中应考虑的安全措施和注意事项。

Construction Plan for 110kV Bus Differential Protection Reconstruction of 220kV Substation

Bus bar protection is an important part of power system relay protection , so bus fault is a very serious fault in the power system .Bus fault affects safe and reliable operation of all devices connected to the bus directly .With the rapid development of electric power technology , the requirement of the rapidi-ty, sensitivity, reliability and selectivity of the bus bar protection is also increasing .Setting 110kV bus differential protection project as an example , the paper introduces the construction of 110kV bus differen-tial protection scheme , and elaborates safety measures and precautions that should be considered in the construction process .
