The fault handling performances of following approaches, namely the coordination among protective relaying devices, the control of automatic reclosing, the control of spare power automatic switching, the coordination of recloser with voltage-time based sectionalizers, the control of recloser and instantaneous protection mode, the neighborhood-based interactive fast self-healing mode and the fault handling performance of centralized intelligent distribution automation system (DAS), are compared. On this basis a fault location and service restoration strategy for distribution networks based on coordination of centralized intelligence and distributed intelligence is proposed, that is, when fault occurs in distribution network, firstly the advantages of distributed intelligence-based devices play a part in clearing the fault and roughly isolating the faulted section immediately, and then after total fault information is collected, the advantages of centralized intelligence-based fault handling such as refined and optimized processing, strong fault tolerance and adaptability play a part, thus DAS accurately locates the fault position and implements the optimized control to finely isolate the fault section and the service restoration is recovered as many as possible. Configuration principles for various faults handling patterns are given, and it is pointed out that the coordination of centralized intelligence with distributed intelligence can draw on each other’s strength, thus the performance of fault handling can be enhanced.
