Reactive power is produced when the current waveform is not in phase with the voltage waveform due to inductive or capacitive loads. The component of current which is in phase with voltage produces real or active power. Major industrial loads need reactive power for sustaining magnetic field. The main reason for reactive power compensation is the voltage regulation at the load side i.e. better utilization of machines connected to the system, reducing system losses, increased system stability. A distribution static compensator (DSTATCOM) is used for load voltage regulation and its performance mainly depends upon feeder impedance & its nature. This paper aims to provide extensive study of design, operation & flexible control of a DSTATCOM operating in voltage control mode. A complete analysis of the voltage regulation capability of a DSTATCOM under various feeder impedances is presented. Then, standard design procedure for computation of the value of external inductor is presented. A dynamic reference load voltage generation scheme is developed which allows DSTATCOM to compensate reactive power at load side during normal operation, in addition to provide voltage support during disturbances.
