Abstract :

One of the major concerns in electricity industry today is power quality problems to the sensitive loads. DVR is a device, used for improving the power quality (PQ) of the load voltage against voltage sags in the source voltage of three phase system. In order to maintain a balanced sinusoidal voltage at the load, DVR has to inject an amount of voltage which can be achieved using the Synchronous Reference Frame (SRF) theory. In this aspect, a method named as PSO is used to minimize VA rating of DVR. In this paper also presents operation and performance of interline dynamic voltage restorer. The proposed control strategy is validated through Simpower system tool box.
