A Development of Shunt Reactor Controlled Energizing Theory

Abstract

The uncontrolled energizing of shunt reactors is accompanied by appearance of a significant DC-component in current, leading to saturation of power and instrument transformers in adjacent network [1], [2]. DC-component causes high inrush current that have an electrodynamic impact on power network equipment [3]. In order to prevent these negative consequences, controlled switching devices providing reactor optimal energizing instant are used.
