Abstract. This paper proposes a fault simulation test method suitable for five divisions of power supply area. Distribution network structures are classified according to different power supply areas and more active interference is injected into test cases, which makes fault scenarios more diverse. Besides, to evaluate the whole process of fault isolation and recovery, the index of fault isolation and index of fault restoration are presented separately, and power recovery rate is provided to evaluate the load transfer capability. In the end, two typical test cases are displayed to clarify the whole test procedure and the use of evaluation method.
