偏移阻抗继电器的整定计算及与方向阻抗继电器的比较

Setting Calculation of Deviation Resistance Relay and its Comparison with Direction Resistance Relay

由于在偏移阻抗继电器的应用中,存在用方向阻抗继电器的整定计算代替偏移阻抗继电器的整定现象,本文给出1种偏移阻抗继电器的整定计算方法,并说明若用方向阻抗继电器的整定计算代替偏移阻抗继电器的整定计算,在某些情况下,将带来很大的误差。结论是:一般情况下是不能代替的。

In the application of deviation resistance relay, during the process of setting calculation, deviation resistance relay is replaced by direction resistance relay, occasionally. The paper provides a way of setting calculation of deviation resistance relay and explicates that under certain conditions, great errors will be made when the setting calculation of deviation resistance relay is replaced by the setting calculation of direction resistance relay. The conculsion is that generally, the two setting calculations are not replaceable.
