POWER DISTRIBUTION PROTECTION COLLABORATIVE ARCHITECTURE INCLUDING FLEXIBLE INTERCONNECTION DEVICE, DEVICE AND COLLABORATION METHOD

摘要

A distribution protection collaborative architecture including a flexible interconnection device, a device, and a collaboration method. Under a frame of collaborative control, the rapid state sensing of a power electronic device of the alternating current (AC) and direct current (DC) flexible interconnection device and the AC side feeder protection control device are used to achieve rapid fault locating and fault removal, enabling rapid self-recovery of a region fault of a full AC and DC system. The present invention is proposed to achieve, by means of a GOOSE communication network based on region high-speed information interaction, global information high-speed communication of smart devices, including the flexible DC interconnection device, in the same AC and DC system, and automatically realize rapid fault locating and isolation of a protection device according to a pre-set condition. With respect to a protection configuration manner of a traditional power distribution system, the present invention has a higher fault handling speed and a better collaborative fault handling capability.
