A new control method for Dynamic Voltage Restorer using matrix converter

Dr. S. Deepa

Abstract :

Dynamic Voltage Restorer (DVR) is used in power distribution system to protect sensitive loads in voltage disturbances. The performance of DVR is related to the adopted configuration and control strategy used for inverters. In this paper, matrix converter controlled with fuzzy logic method based on synchronous reference frame controller, is used to improve operation of DVR to compensate voltage sag/swell. Also, the multi loop controller using the Posicast and P+Resonant controllers is proposed in order to improve the transient response and eliminate the steady–state error in DVR response, respectively. Simulation results using MATLAB/ Simulink are presented to demonstrate the feasibility and the practicality of the proposed novel Dynamic Voltage Restorer topology.. The simulation results of new DVR presented in this paper, are found quite satisfactory to eliminate voltage sag.
