Abstract :
This paper investigates the performance of the DVR for enhancing voltage dips in medium voltage (MV) distribution networks with secondary distribution configuration. The DVR compensator is analyzed as a rectifier & inverter based voltage controller. Matlab/Simulink modeling of DVR and his control strategy are presented. The DVR performances are compared for different grid connection of the DVR rectifier. The obtained results demonstrate the performances and the benefits of dynamic voltage restorer use in power networks with secondary distribution structure, and help us to choose the proper supply configuration for the DVR rectifier.
