Improved digital algorithm for adaptive reclosing for transmission lines with shunt reactors

IET Generation, Transmission & Distribution, 2016
This study presents an improved algorithm of adaptive single‐phase auto‐reclosing (ASPAR) for extra high voltage transmission lines with shunt reactors. It shows that the odd and even harmonic factors of the faulted phase voltage have different characteristic in different stages after breaker open.
