Abstract: In distribution system, Power Quality problems affecting sensitive equipment’s. There are different types of problems in power quality. These problems are power factor, reactive power compensation and harmonic distortion. Different types of FACT devices are used. These FACT devices are SVC, STATCOM, IPC, DVR, UPFC, TCSC, TCPST and DSTATCOM. D-STATCOM is a custom power device which is installed in parallel with distribution system. Regarding problems of power quality, these devices are used but for getting better response, D-STATCOM is used. There are various modulation techniques and also control techniques are available for implement these problems. These techniques are PWM, SPWM (modulation techniques) and other techniques are Phase Shift Control, d-q theory, Synchronous Reference Frame (SRF) model etc. And with reference frame model using PI controller the DSTATCOM can be controlled. DSTATCOM is used to reduce harmonic distortion, reactive power compensation and power factor improvement. In this paper we control the Voltage Source Converter (VSC) for mitigate harmonic distortion and reactive power compensation. The simulation was carried out with the help of SIMULINK & MATLAB software.
Keywords: reactive power compensation, D-STATCOM, Voltage Source Converter (VSC), PWM, SPWM.
