Introduction to a modern control system for DVR with minimize the losses

the losses in DVR has direct relationship to its performance i.e. there is no disturbance that it has been considered in the normal functioning of the network and in the presence of conflict (compensation time). A main determinant factor of the amount of losses after arrangement of power system which is related to control system. The control system is divided to two important parts: voltage references and switching patterns. the design of control system for DVR so to be performed while compensation of voltage sag, voltage swell, Harmonic voltage, limiting fault current and compensation of voltage unbalance has minimal loss and highest accuracy. In this paper, the loss in the proposed DVR and several samples of them through generation of the voltage references and different pattern switching are reviewed and compared. The simulation results of PSCAD/EMTDC software show the accuracy and speed of proposed DVR.
