A dynamic voltage restorer is a power quality (custom power) device used to correct the voltage disturbances by injecting voltage as well as power into the system. The compensation capability of a dynamic voltage restorer (DVR) depends primarily on the maximum voltage injection ability and the amount of stored energy available within the restorer. In this paper a new phase advance compensation (PAC) strategy for the DVR is proposed in order to enhance the voltage restoration property of the device. Also a method of determining the exact amount of voltage injection required to systematically correct a specific voltage drop with minimum active power injection is proposed. Using the proposed method it can be shown that a particular disturbance can be corrected with less amount of storage energy compared to that of existing in-phase boosting method. Analytical expressions for both the magnitude and angle of the injected voltage are also derived. A closed-loop controller that consists of an inner current loop and an outer voltage loop is also incorporated into the DVR system.

Voltage dip in the distribution network is caused by disturbance at different voltage levels and experienced by low voltage customers are established. Voltage dips are those disturbances which damage the power quality of the distribution network and causing heavy economic damage to the customers. This chapter investigates procedures of mitigating the voltage dip by reducing the number of faults due to short circuits, lowering the fault clearing time, and changing the power system design and DSTATCOM Compensator with DG and dynamic voltage restorer.

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
