Abstract	Most single-phase adaptive reclosure (SPAR) schemes are dependent on the voltage of the fault phase to distinguish between permanent and transient faults. As transmission lines with shunt reactors that compensate the influence of the distributed capacitance, the voltage of tripped phase is so minor that the error of potential transformer (TV) limits the applications of voltage-based SPAR schemes. Therefore, a SPAR scheme using parameter identification principle is proposed in this paper. The scheme uses transient fault model (after fault arc extinction) as the prototype, and solves the inductances of shunt reactor and neutral reactor, and utilizes the difference between the solved inductances and the actual ones to distinguish permanent fault from transient fault. In the case of transient fault, the difference is minor because the actual fault model is close to the prototype. But for permanent fault, the difference is distinct for the actual fault model is inconsistent with the prototype. ATP simulation results show that the proposed scheme can reliably and effectively distinguish permanent fault from transient fault, and promises to be applied to the auto-reclosure in transmission lines with shunt reactors.
