Practical Implementation Of UPQC Under Non-Linear Loading Condition

摘要

Non-linear load adversely affect the voltage stability of the distribution system. If not checked at time the generated harmonics may propagate further and can severely damage the supply system. Non-linearity of load generates harmonics which if not filtered out may damage the connected equipments. In this paper dual compensation based unified power quality conditioner has been proposed to rule out the harmonics of the system. The controller is designed using sinusoidal current as well as voltage source converter which take care of both voltage as well as current control. The steady state error is removed using PI controller.
