Optimal Configuration of Current-Limiting Reactor in Special Distribution Network Based on PSO
Based on analyzing the existing problems of the short line overcurrent protection in special distribution networks,this paper proposes an optimal configuration method for current-limiting reactor.By increasing the short circuit current difference between higher and lower protection,the overcurrent protection setting time is optimized.Particle swarm optimization algorithm is employed to configure current-limiting reactor,achieving the optimal configuration between current-limiting reactor installation location and the impedance value on the premise of maintaining the power system stability.Finally,the configuration calculation by the proposed algorithm in a coal mine power supply system helps formulating the feasible current-limiting reactor configuration scheme.
