交直流混合配电网中多MMC单相接地故障的零序电流与电压控制策略

The ac/dc hybrid distribution network (HDN) is facing great challenges under single-phase ground (SPG) fault. To ensure the continuous and stable operation of ac/dc HDNs, it is essential that the converters have fault control and relay protection capabilities. The previous studies focused only on a single converter, this article first proposes a zero-sequence current and voltage control strategy f...
