In the power plant power system, voltage drops often occur and one of the contributing factors is a short circuit that affects the performance of motor drivers on the mills in the generator. In this research proposed the use of compensation dynamic voltage restorer (DVR) to damped voltage sag. The DVR using a three-phase voltage source inverter (VSI) with voltage loop control (PI). To detect the voltage drop system using park transform and apply it in the voltage regulator as a control system function that detects the voltage amplitude at the sensitive load continuously. The result of simulation in system distribution with active load 280 kVA and 50 kVAR reactive, before a voltage compensation system 0.67 pu and after voltage compensation system becomes 0.99 pu on nominal voltage 0f 380V. The performance of DVR is reliable because it is able to compensate quickly to changes in the value of the voltage
