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.

Distibuted generation and reclosing coordination

, 2004
Distributed generation has many detrimental impacts on reclosing. DG may continue operation during the dead time feeding fault current and thus prevent arc extinction.
