摘要(Abstract)：

换相失败是直流输电系统逆变器最常见的故障之一,通常故障清除后直流系统可以恢复换相,周期性换相失败很少发生,过去国内从未出现过换相失败闭锁直流的情况。通过对林枫直流现场数据的深入分析,得出换相失败持续时间达到保护定值,保护正确动作;而励磁涌流引起枫泾站换流母线电压畸变、阀控VBE对已关断阀执行重触发以及换相失败恢复期间直流电流过冲等因素是导致林枫直流发生周期性换相失败的主要原因。在此基础上,基于电磁暂态程序建立了林枫直流输电研究模型,其中控制保护采用了与实际工程一致的详细模型,通过仿真研究提出了极控系统的改进措施:取消瞬时电流控制、优化换相失败预测和低压限流等功能,最后在林枫直流输电工程中进行了现场验证试验,试验结果验证了所提措施的有效性。
