Abstract

Abstract: In the petal-shape regional distribution network, the fast power recovery cannot be realized with the traditional auto transfer system when a power failure occurs at the non-standby-switch room. To solve this problem, based on the idea of real-time sampling, real-time data exchange, real-time judge, and real-time control, a regional power grid auto transfer system is proposed in the paper based on the high-availability seamless redundancy (HSR), which can be used in various complicated regional distribution network structures. The composition, communication structure and logic control strategies of the regional power grid auto transfer system are discussed in the paper. The field application of the developed devices of the regional power grid auto transfer system shows that the system can effectively realize the rapid recovery of power supply after failure of the petal-shape distribution network.

Key words: regional distribution network, regional power grid auto transfer system, high-availability seamless redundancy (HSR), fast power recovery control
