| 摘 要： | 采用带比率制动特性的差动保护原理的微机型母线保护在电力系统中得到广泛应用 ,但它的定值整定不能简单地套用原有的母线保护整定原则 ,以WMH80 0型微机母线保护为例 ,重点就差动保护定值、电压闭锁定值进行一些原理分析 ,提出了微机型母线保护定值整定的参考意见。

| Abstract: | Numerical busbar protective relay based on current differential principle with ratio restraining characteristic is used widely in the electric power system.Its setting method can't keep to the old principle indiscriminately.This paper introduces the setting principle of WMH800.Especially it analyzes the theory that how to calculate the differential setting value and the voltage interlock setting value and etc. Some reference principles for the setting calculation of numerical busbar protection is provided. |
