The high-quality control of a single-phase grounding fault is important for supporting the safe operation of novel distribution network. However, the existing active-type arc suppression devices (AASDs) have some common problems, such as single function and high cost. To address these issues, a topological structure of AASD based on heterogeneous unit (HU-AASD) and its control strategy are proposed. First, the fourth arm is used to provide voltage support for the virtual neutral point of the HU-AASD, and the withstand voltage requirement of three-phase arms are reduced to the phase voltage, thus reducing the cost and volume of AASDs. Second, the capacitive and inductive reactive power compensation capabilities can be provided by the proposed scheme, and the HU-AASD can continuously provide reactive power compensation for the power grid after the single-phase grounding fault occurs, thus providing uninterrupted voltage support for the distribution network. Finally, simulation and experimental results demonstrate the validity and feasibility of the proposed topology and its control strategy.
