Abstract—Voltage sag is a major problem in power system that must be solved. To overcome the occurrence of the voltage sag, a system that well known as Dynamic Voltage Restorer (DVR) is needed. In an electrical power system, DVR is positioned in series between a source and load. There are several DVR voltage compensating methods,such as pre-sag method, in-phase method and in-phase advance compensation. DVR need synchronization time for equals phase injection voltage so it can compensate voltage sag due to short circuit current. This work employs Discrete Fourier Transform (DFT) for phase detection and hysteresis voltage control. This paper presents modeling, analysis and simulation of DVR by using MATLAB.

Keywords— electric power quality; voltage sag; dynamic voltage restorer; hysteresis voltage control.

I. INTRODUCTION Many developing countries require increased productivity

in industry, to achieve high productivity, industry requires power electronics components, where power electronics component is a sensitive device that must be supplied by a voltage that has frequency and magnitude at constant conditions [1]. Power electronics components are required high-power quality[2],[3], because electronics components are very sensitive to electromagnetic fault [4]. Such a fault causes problems of power quality, failure in providing high power quality can cause failure of equipment operation or even shutdown on a system, power quality problems are: voltage sag, flicker, voltage unbalance, interruption and harmonic. Voltage sag is one factor causing the diminished electrical power quality, one of causes of voltage sag is short circuit current. To mitigate the voltage sag, one can use Dynamic Voltage Restorer (DVR) [5], [6].DVR placed at point of common coupling, at customer side. So that DVR can protect load by injecting voltage for mitigation voltage sag.

II. DYNAMIC VOLTAGE RESTORER

A. Principle of DVR Operation Fig. 1 shows the block diagram of DVR. The basic idea of

DVR is to inject voltage from injection transformer, wherein voltage of injection transformer comes from inverter, in this work, the inverter is controlled using hysteresis control with

phase detection .

Fig. 1. Basic Circuit of DVR [7]

B. Basic Configuration of DVR • An Injection/ Booster transformer: The main task of

injection transformer is to connect DVR to distribution network via the HV-windings and transforms and couples injected compensating voltages generated by voltage source converters to the incoming supply voltage.

• Filter Unit: The main task of harmonic filter is to keep the harmonic voltage content generated by voltage source converter (inverter). Non-linear characteristics of semiconductor devices cause distorted waveforms associated with harmonics. To overcome this problem and providing clean electrical supply filter unit is used.

• Voltage Source Inverter Circuit: Inverter circuits convert DC voltage to AC voltage. Solid-state semiconductor devices with turn-off capability are used in inverter circuits. In DVR application, VSC is used to generate voltage for mitigation voltage sag.

• Energy Storage Unit: Purpose is to supply necessary energy to inverter via a dc link for the generation of injected voltages. Batteries and Ultracapacitors are most common types of energy storage devices. In fact, capacity

of the stored energy directly determines the duration of sag which can be mitigating by DVR.

C. Control scheme of DVR Fig. 2 shows the flowchart of DVR operation, the first

step of the control technique is phase detection by Discrete Fourier Transform (DFT) that used for reference voltage. the control output of the DVR to generate switching signal for inverter is generate based on error between reference and actual voltage.

III. HYSTERESIS VOLTAGE CONTROL WITH DETECTION PHASE

Hysteresis control is a feedback controller that compares two statements that produce a switching signal from difference of two statements.

As in Fig. 3 (a) hysteresis control generally consists of a 3-phase IGBT inverter, battery for energy storage, injection transformer and hysteresis controller. Hysteresis controller requires two voltage signals, which are from supply voltage side and from injection transformer where voltage is injected by DVR. Hysteresis controller will compare two signals, and produce an error signal that is forwarded to hysteresis switching pattern according to fig. (b). This hysteresis controller uses bands (VH (upper) and VL (lower)), where if error signal is between upper and lower there is no switching signal and when signal errors�upper, switching signal will decrease and vice versa, as in fig. (b) and (c).
