摘要
分析了波阻抗方向继电器在各种正反向故障时的动作行为，使用ＥＭＴＰ对继电器原理和算法进行了大量的数值仿真验证。结果表明：所提出的继电器与故障类型、故障距离、过渡电阻无关，不反映电力系统振荡。在零初相角、近距离故障时仍然具有良好的动作性能。
The paper analyzes the operating performances of the surge impedance relay (SIR). The influence of bus capacitance for the relay is studied firstly, followed by case study of every fault configuration. Theoretical analysis and EMTP simulation results suggest that the performance of the relay is immune from fault configuration and load conditions. And satisfactory performance can be expected in even in zero-voltage and close-up faults.
