| 摘 要： | 介绍了基于直流系统电磁暂态（electro-magnetic transient in DC system，EMTDC）建立的直流输电控制系统，该控制系统两侧均有定电压控制器，可通过调整直流电压参考值实现直流系统的降压运行。仿真实验结果表明：该控制系统电流指令追随性好，在直流电流下降后的恢复过程中，能有效抑制直流电压和电流的波动；在逆变侧发生单相接地故障时，由于整流侧有最小触发角限制作用，在逆变侧有故障恢复启动功能，因此在故障时能保持较大的熄弧角，在故障恢复过程中有很强的协调能力和控制能力。

| Abstract: | The DC transmission control system based on electro-magnetic transient in DC system(EMTDC) is described,which is equipped with constant-voltage controllers on both sides to realize step-down operation of DC system by modifying the direct voltage reference.Simulation experiment results show that the control system is good at following current order,able to restrain the swing of direct voltage and current effectively while recovering reduced direct current;in case of single-phase earth fault on inverter side,... |
