摘要
When a sudden load is connected to the distribution system Voltage sag takes place.DVR (Dynamic Voltage Restorer) is one such custom power device which helps in mitigating voltage sag. The DVR injects required volt-ampere to the system in order to maintain nominal balanced sinusoidal voltage at the load. The operation of DVR is depends on the control technique used. In this paper four control techniques are used, the techniques used are pre sag compensation method, in phase compensation method, energy optimization method and in phase advanced compensation method for mitigation of voltage sag. The performance of all the four methods compared. It is observed that in phase advanced compensation method has given better results in magnitude of voltage sag and THD compared to other methods. The simulations are carried out by using MATLAB / SIMULINK software.
