电厂变压器的纵联差动保护及整定

Longitudinal Differential Protection and Setting of Transformer in Power Plant

变压器的继电保护整定计算是继电保护安全运行的重要组成部分,当继电保护整定计算不合理造成继电保护拒动或误动,就会引起电气事故扩大造成严重后果。文章主要以发电厂变压器为例,介绍继电保护的整定计算过程。

The setting calculation of relay protection of transformer is an important part of safe operation of relay protection. When the setting calculation of relay protection is not reasonable, it will cause the relay protection to refuse to operate or misoperate, which will cause the electric accident to enlarge. This paper introduces the setting calculation process of relay protection by taking the transformer of power plant as an example.
