Custom power instruments are of the most prominent compensators of power quality in distributed network. Among these, to compensate the voltage, DVR has the best performance. In this research sliding mode control of DVR is proposed. Also, among the common methods of voltage compensating, pre-sag method which is an effective and useful method of voltage improvement, has just used. This method compensates the voltage amplitude and has retrieval feasibility of voltage angle of each phase to pre-sag value as well. The performance of such a controlling system simulated, analyzed and investigated by Matlab/Simulink in sinusoidal states of network. To assess the voltage quality and observing the performance of DVR by recommended method, the load voltage THD has been calculated. Simulation results show the efficiency and performance haste of the recommended method. © 2012 IEEE.
