A Service Restoration Method for Multiple Faults in Distribution Systems Based on Load Balancing Distribution

Abstract:

Current service restoration methods in distribution systems mainly focus on the single fault. When the distribution system deals with more than one fault, current service restoration methods will not be applicable. A service restoration method for multiple faults is proposed to solve the problem mentioned above. Fault outage areas connected through a loop switch compose an unaided fault recovery area which is regarded as a service restoration unit. In order to eliminate the interaction of communal feeders which are connected to more than one unaided fault recovery area, each communal feeder is decoupled into multiple virtual feeders which are assigned to corresponding unaided fault recovery areas based on load balancing distribution. After the process above, the fault recovery area of multiple faults is divided into several independent fault recovery areas and each independent fault recovery area can be restored by traditional service restoration methods. So the contribution of this algorithm is to solve the problem of service restoration of multiple faults. The result of a calculation example proved the validity of the algorithm.
