摘要
打破常规,合理调整继电保护时间级差,可实现在特短线路上用常规继电保护装置作为主保护的方案,对解决公司电网中压系统继电保护定值的配合起到关键作用。
Breaking free from conventions and rationally regulating time grading of relay protection may use a general relay protection device as a main protection on a short line.It plays an important role in fitting of fixed value of relay protection for the medium voltage system in the power grid of a company.
