IMPLEMENTATION OF REACTORS WITH UNGROUNDED NEUTRALS UNDER EXCESS VOLTAGES IN LONG-DISTANCE POWER TRANSMISSION

A. M. Hashimov, R. N. Huseyn

Abstract


In long distance power transmission over , overlapping is one of the main problems of limiting extreme voltages. In order to eliminate extreme voltages it has been proposed to use star-shaped reactors with ungrounded neutrals, which are connected at the beginning and at the end of the transmission lines in parallel to shunting reactors and the curves of their graphs are shown. The graphs show the maximum values of the fluctuation curves at the neutral of the reactor, at the beginning and at the end of the line.

Keywords


overhead power lines, overvoltage, shunt reactors(SR), ungrounded reactors(UR), compensation, traditional shunt compensation, long distance power transmission lines, automatic circuit reclosing (ACR).
