ABSTRACT

To solve the problem of single-phase adaptive reclose in line with series compensation, this paper proposes a criterion using the different frequency components belonged to the recovery voltage to defect transient faults and permanent faults. Firstly, this paper analysis the frequency characteristics after fault-phase circuit breaker tripped in single-phase ground fault, establishes the recovery voltage identification model including the DC component and each component. When single-phase-to-ground fault occurs and both sides of the circuit breaker open, the recovery voltage as a known quantity, each frequency component is obtained by least square fitting. The amplitudes of various frequency components are adopted to distinguish the permanent faults from transient faults. Through theoretical analysis and PSCAD simulation show that the criterion is correct and effective and can detect the nature of single-phase fault quickly.
