摘　　要：依据模块化多电平换流器(MMC)型电压源换流阀实际工程运行工况,采用等效试验的方法,设计了一种MMC型电压源换流阀运行试验系统,对换流阀的稳态工况和暂态工况进行模拟,进而实现对换流阀的导通、关断和有关电流特性的检验,并且提出了一种可行的闭环控制策略来协调3个电流环的控制,从而达到对基波电流、二倍频电流以及直流电流精确有效控制的目的。详细介绍了MMC型电压源换流阀运行试验系统的主回路设计,并以实际工程换流阀组件为试验对象,验证了所设计的MMC型电压源换流阀运行试验系统的正确性和实用性。According to the actual engineering operational conditions of the modular multilevel converter(MMC) type voltage source converter valve,an equivalent test method is adopted to design an MMC type voltage source converter valve operational test system,which can realize the steady-state condition of the converter valve simulate with transient-state condition,and then realize the inspection of the on,off and related current characteristics of the converter valve.In the meantime,a feasible closed-loop control strategy is proposed to coordinate the control of the three current loops to achieve the purpose of precise and effective control of the fundamental current,the double frequency current and the DC current.The main circuit design of the MMC type voltage source converter valve operational test system is introduced in detail,and the actual engineering converter valve assembly is taken as the test object to verify the correctness and practicability of the designed MMC type voltage source converter valve operational test system.
