Abstract

Power quality characteristics of Electrical substations feeding CNG stations as nonlinear and time variant loads which cause high amount current and power variations and low power factor for their feeding power systems are investigated. The power quality characteristics of the substation are verified through experimental measurements with the help of power quality measurement instruments. In addition, the application of an efficient static var compensator in the structure of TCR-FC has been proposed for voltage fluctuation reduction, reactive power compensation and power factor improvement. Through the simulations done with Matlab-Simulink the efficiency of the proposed SVC is verified.
