Fault recovery is the key link to realize self-healing of intelligent distribution system in the future. It plays an important role in meeting the demand of power supply and reducing the loss of outage. For active distribution network with distributed generations, a fault recovery method considering active management measures is proposed. Considering the distributed power output regulation and the capacitor group reactive power compensation constraint, firstly, the active distribution network islanding model is constructed, and the depth-first search combined with the breadth-first search algorithm is used to divide the islands. Then, the active distribution network fault reconfiguration model is established, which is transformed into a mixed integer second-order cone programming model for fast solution by second-order cone relaxation technique. Finally, the improved IEEE 33-bus active distribution network is simulated, and the results show that the proposed model and method are reasonable and effective.
