摘要
详细分析了有串补电容线路上工频变化量距离继电器的性能 ,得出工频变化量距离继电器应用于串补线路在不计暂态过程时能够正确动作 ,而在计入暂态过程时可能存在暂态超越。在此基础上提出了防止暂态超越的措施——提高动作门槛。EMTP仿真程序结合保护仿真程序验证了上述理论分析的正确性和防止暂态超越方案的有效性。
Performance of incremental power frequency distance relay on series capacitor compensated lines is studied in this paper with the result that it can operate properly if the fault transient process is not taken into Consideration, otherwise, it will overreach. Based on above research, a method enhancing the operating threshold is presented, which prevents the relay from overreaching. It is verified by EMTP program and incremental power frequency distance relay simulation program.
