Abstract

With the long-running 500 KV substation which facing the problem of a whole secondary equipment aging, the secondary equipment of general Station will carry on intelligent transformation one by one. In this paper, we take Shuanglong 500 KV station in Jinhua for example, which has Phased blackouts intelligent transformation. It describes in detail using transition interface device to solve the problem of bus differential protection Retrofitting in the Intelligent transformation process, which provides core technical support for substation secondary equipment intelligent transformation.
