差动保护比率制动整定中动作电流与制动系数等关系分析

Analysis of the relationship between operation current and restraint coefficient for ratio restraint setting of differential relay

通过对差动保护比率制动整定中动作电流与制动系数等关系分析 ,澄清了以往整定中的一些错误概念 ,并介绍了差动保护比率制动的整定步骤。

By analyzing the relationship between the operation current and restraint coefficient in ratio restraint setting of differential relay, some wrong concepts in past setting operation is corrected. The detailed setting steps are introduced for ratio restraint of differential relay.
