METHOD FOR OPTIMIZING REACTANCE TO REDUCE TORSIONAL TORQUE OF SHAFT IN TURBINE GENERATOR, AND METHOD AND APPARATUS FOR RECLOSING POWER LINE USING THE SAME

摘要

An apparatus for reclosing a transmission line according to the present invention, which is connected to a turbine generator via a first bus and a system via a second bus, comprises a reclosing controller for calculating optimized reactance and generating a first blocking signal and a second blocking signal for opening and reclosing the transmission line, respectively, if a fault occurs at the transmission line; and a reclosing blocking part for opening and closing a main passageway of the transmission line by the first blocking signal and opening and closing a detour passageway, which bypasses the main passageway, by the second blocking signal, and if the detour passageway is connected to the transmission line in place of the main passageway, additionally providing the reactance optimized by the reclosing controller for the transmission line via the detour passageway.
