- A novel method using mode component inductance parameter of shunt reactors is presented in order to identify temporary faults and permanent faults for three-phase adaptive reclosure on transmission lines with shunt reactors at both ends. The method uses π-type equivalent model as the prototype to build parameter identification formula. When some single phase-to-ground fault occurs, the parameter identification formula of zero-mode component is built; when some phase-to-phase fault occurs, the parameter identification formula of line-mode component is built. The current of the shunt reactor is given and the inductance of the shunt reactor is taken as the unknown parameter to evaluate the difference between the calculated inductance and the actual one so as to distinguish permanent fault from transient fault. The inductance difference of the temporary fault is minute because the actual fault model is consistent with the prototype. But the inductance difference of the permanent fault is distinct because the actual fault model is inconsistent with the prototype. Results of EMTP simulation show that the proposed method is reliable and effective, and can be applied to the three-phase adaptive reclosure on transmission lines with shunt reactors.
