| 摘 要： | 采用自关断功率半导体器件的电流源型主动换相换流器(actively commutated converter,ACC)具有有功与无功功率可解耦、不存在换相失败、无需大量储能电容等特点,在高压直流输电领域具有较好的应用前景。该文针对适用于高压直流输电(high voltage direct current,HVDC)的ACC功率半导体器件及其均压方法、电路拓扑、调制方法、功率特性、控制策略、故障及保护方法等进行调研和分析。结合具体实例,将ACC与现有HVDC的2种换流器,即电网换相换流器(line commutated converter,LCC)和模块化多电平换流器(modular multilevel converter,MMC)进行对比分析。同时,对ACC的潜在应用、存在的问题以及发展的方向进行总结和归纳。

| Abstract: | Current-source type actively commutated converter(ACC) using self-turn-off power semiconductors is characterized by decoupled control of active and reactive power, avoidance of commutation failure, no requirement of a large amount of energy storage capacitors and so forth. ACC has good application prospects in high voltage direct current(HVDC) transmission systems. This paper reviewed and analyzed the power semiconductors with voltage sharing technology, converter circuit topology, modulation method, active and reactive power characteristics, control schemes, fault and protection problems of ACC for HVDC applications. The comparisons among ACC, the conventional line commutated converter(LCC) and modular multilevel converter(MMC) were also done for a specific HVDC inverter with the same voltage rating, current rating, and power semiconductor stresses. This paper also analyzed the potential application scenarios, the existing problems, and future trends of ACC technology. |
