Performance measurement of Static Var Compensators in distribution system

The main purpose of this paper is to study performance measurement of the Static Var Compensator (SVC). The SVC has been widely employed in industrial electric systems, especially in plants with electric arc furnaces for steelmaking. Electric arc furnaces result in power quality problems, such as voltage sag, flickers, phase unbalance, low power factor, and harmonics. The way of compensation is either to supply or to absorb reactive power and SVCs are adopted for performing compensation. Results from the performance measurement of a SVC installation for the compensation of an electric arc furnace are demonstrated. It is found the SVC is capable of mitigating power quality problems, improving power factor, and upgrading power transfer of the studied system.
