In view of the problem of fault location in double star shunt capacitor bank

a kind of single phase fault location method based on neutral unbalance current in double star shunt capacitor bank is propsoed in this paper.The method can

by analyzing the relation between phaseand amplitude of unbalance current and fault current of the neutral point

quickly and intuitively locate the phase of the faulty capacitor

fault branch and number of faulty capacitor units

can solve such problem as no intuitive and low efficiency of the fault point of such shunt capacitor bank in the single phase fault and the the correctness of the method is varified by the PSCAD simulation.
