Blue Eyes Intelligence Engineering & Sciences Publication Pvt. Ltd. Review Paper on Applications of D-Statcom in Distribution System

Abstract-In recent years the power quality problems is a big issue in distribution system. 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 like as SVC, STATCOM, IPC, DVR, UPFC, TCSC, TCPST and DSTATCOM can be used to solve these types of problems. But now a days D-STATCOM is using to mitigate these problems of power quality. It 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 techniques and also control techniques are available for implement these problems. These techniques are PWM, SPWM, SVPWM, PDPWM (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. In this paper the applications of DSTATCOM are discussed. DSTATCOM can be used in distribution system, wind power, solar power generation and also used with fuzzy system. The simulation of test model was carried out with the help of SIMULINK & MATLAB software
