The integration of distributed generation brings great change to the operation mode of the distribution network, and higher requirements have also been set for the fault recovery scheme. Analysing the relationship between fault reclosing and voltage variation of the distributed generation in distribution network and considering the influence of reclosing on LVRT of DG, this paper proposes a new fault recovery scheme cooperating with reclosing and LVRT (low voltage ride through) for active distribution network. The planned isolated island area is divided in advance for each DG, and different fault recovery methods are implemented according to the different fault conditions of the fault location, the isolated island area and the voltage variation of the distributed generation. The feasibility and effectiveness of the proposed scheme are verified by simulation in PSCAD.
