Abstract

A novel single-phase adaptive reclosure scheme based on capacitance parameter of transmission line is proposed

where transient fault model is considered as the prototype

and the capacitance as the unknown parameter to evaluate the difference between the calculated capacitance and the actual one for distinguishing the transient and permanent fault. In the case of transient fault

the difference is small for the actual fault model is consistent to the prototype

but for the permanent fault

the difference is notable

and the actual fault model does not coincide with the prototype. By means of only using the currents from the two-terminal shunt reactors

the criterion gets simple to perform. Moreover

the algorithm is independent of the low-frequency swing component. ATP simulation results show that the scheme enables to effectively distinguish permanent fault from transient fault

and improve the action success rate of the single-phase adaptive reclosure in transmission lines with shunt reactors.
