摘 要: 直流换流阀是高压直流输电工程的核心装置,其额定容量很大,在进行换流阀运行试验时,为降低试验容量,采用合成试验方法是一个合适的选择。提出了一种合成试验回路,能够正确地再现换流阀实际运行的电压与电流波形,符合运行试验的标准,而且能够满足运行试验的等效性要求。采用电力系统仿真软件Matlab/Simulink 对该回路进行仿真研究,并搭建了按比例缩小的物理模拟试验回路进行验证,结果表明该合成试验回路的设计是可行的,可为高压换流阀运行试验装置的开发提供参考。

Abstract: Thyristor valve with large rated capacity is the core device of high voltage direct current (HVDC) transmission project. During thyristor valves performance test, in order to reduce test capacity, synthetic test circuit was adopted to meet the research needs of its test methods. A kind of synthetic test circuit was proposed to reproduce the voltage and current waveforms of thyristor valves operation accurately, in accord with standards of performance test, and the circuit met the equivalent requirements of performance test. The simulation software Matlab/Simulink of power system was adopted to study the circuit and the scaling-down physical simulation test circuit was built up to carry out performance test. The results show that the designed synthetic test circuit  is feasible, which provides references for the development of high voltage thyristor valves performance test.
         Key words: high voltage direct current transmission; thyristor valve; synthetic test circuit; equivalence; physical model
