Reactive power (VAR) compensation techniques in high voltage transmission lines

Abstract

Management of reactive power and voltage control constitute part of the major challenges in a power system. Appropriate reactive power management and control solves power quality problems, reduce losses, improve power factor, maintained a balanced voltage profile at all power transmission levels, improved system efficiency and stability. This paper examined the brief idea about the mode of operations, design characteristics of various types of reactive power compensation techniques. These techniques are used to improve the performance of AC transmission & distribution systems. They enhance the stability of the AC transmission system by increasing the active power that can be transmitted thereby enhancing the overall working of the electric power system.
