Abstract: In view of low efficiency,poor accuracy of traditional distribution automation system detection,some detection schemes are developed according to public and self-built network and implemented step by step.On the basis of flexible network configuration,advanced techniques,such as terminal injection,uninterrupted power,active interference,scenario reproduction are studied.Field detection shows that:compared with other testing programs,the detection schemes supported by flexible network configuration can realize sustainable interference simulation detection and successfully reduce detection coordination difficulty and detection time,while improving distribution system intelligence level and operational reliability.
