基于电力电子技术的混合交直流主动配电网故障电流限制与能量回馈

The active distribution networks have a tendency to develop toward hybrid ac–dc systems constructed by power electronics, the magnitude and direction of power may change randomly at any time, making the usual protection potentially insensitive, raising the negative impacts of single-phase ground (SPG) fault which accounts for the majority of all faults that occurred in medium-voltage (MV) distribu...
