摘　　要：控制脉冲是判断换流阀换相阶段,实现新型换流阀主动关断控制策略的重要参考信号。本文首先分析实际工程中与合成试验回路阀控系统中控制脉冲的时序差异,提出使新型换流阀关断控制策略适用于合成试验回路的控制脉冲改造需求,并基于有限状态机设计一种合成试验回路控制脉冲改造方法。然后,分析该方案下合成试验回路控制脉冲的稳态运行时序控制、异常时序恢复及特殊工况时序控制。最后,对合成试验回路进行改造并测试。测试结果表明,该方案满足预期改造要求。The control pulse is an important reference signal for judging the commutation stage of the converter valve and implementing the active shutdown control strategy of the new converter valve.This article analyzes the timing differences of control pulses between actual engineering and synthetic test circuit valve control systems,proposes control pulse modification requirement to make the new converter valve shut-off control strategy applicable to the synthetic test circuit,and designs a modification method for synthetic test circuit control pulses based on finite state machines.Then the steady-state operation timing control,abnormal timing recovery,and special operating condition timing control of the synthetic test circuit control pulse under this scheme is analyzed.Finally,the synthetic test circuit is modified and tested,and the results show that the scheme can meet the expected modification requirements.
