In the distribution systems to protect consumers from the sudden variations in the voltage magnitudes based on the presence of voltage sags and swells are main issues in distributions these types of problems are compensated by placing the dynamic voltage restorer (DVR) in the distribution side. In this paper we are implemented the multi functional dynamic voltage control strategy with the posicast and P+ controllers are implemented to enhance the transient response and overcome the steady state

In this paper we can control the different problems such as voltage sags and voltage swells also we can compensate the induction motor starting torque problems and three fault conditions with under downstream fault conditions also explained. The current condition is restore the point of common coupling arrangement is provided the voltage and protects the DVR itself to identify the problems and compensate those problems very effective manner. The corresponding simulation results are discussed in the MATLAB/ SIMULINK.
