摘要：

It is very important to obtain high reliability in the high-voltage direct current (HVDC) system operation because of extremely high and huge power capacity. To guarantee the reliability IEC-62501 standard requires valve test for the voltage source converter (VSC) HVDC system. This paper proposes a test circuit for modular multilevel converter (MMC)-based HVDC valve. The proposed scheme has good features of adequate test current generation, considerably reduced power supply voltage, simplified test circuit topology, etc., compared to the conventional test circuits. The validity of the proposed scheme is verified through experimental results.
