摘要
通过对湘东某水电站一起变压器差动保护误动作原因的分析,提出了对变压器差动保护进行带负荷测试的必要性,并着重介绍了带负荷测试数据的获取方法、带负荷测试数据的分析,并以此来发现差动保护中存在的各种问题。
This paper analyzed the reasons of mal-operation accident of transformer differential protection, which happened in a hydroelectric station on the eastern Hunan, then gave the necessity of load testing on the transformer differential protection, and focused on the methods to get and analyze the data of load testing, and find the problems that exist in the differential protection.
