摘要

本文利用传输线的双pi模型,研究了考虑传输线电容的距离继电器测量阻抗。由此提出了距离继电器的理想脱扣特性。将测量的阻抗和脱扣特性与不考虑线路电容的情况进行了比较。在故障电阻为零的情况下,还研究了线路电容引起的测量阻抗与准确值的偏差。

Measured Impedance by Distance Relay Considering Double Model of the Line Capacitance
This paper investigate the measured impedance by distance relay considering the transmission line capacitance by utilizing a double pi model for the line. The distance relay ideal tripping characteristic is therefore presented. The measured impedance and the tripping characteristic are compared with those in the case of not considering the line capacitance. In the case of zero fault resistance, the deviation of the measured impedance from its exact value caused by the line capacitance is also investigated.
