一种无需桥臂电流传感器的MMC环流抑制控制新方法

The occurrence of grid-side faults causes imbalance and distortion of ac side voltage. Thus, the operation of modular multilevel converter (MMC) system under grid imbalance is becoming important to improve the reliability of power system. Under unbalanced grid conditions, the use of a-b-c stationary reference frame-based controller can simplify the control structure because it can avoid decomposin...
