Paper Title
Reactive Power Compensation Using Dstatcom

Abstract
Reactive power is produced when the current waveform is out of phase with the voltage waveform due to inductive or capacitive loads. Current lags voltage with an inductive load, and leads voltage with a capacitive load. Only the component of current in phase with voltage produces real or active power. Major industrial loads for example transformers, furnaces, induction motors etc… needs reactive power for sustaining magnetic field. The main reason for reactive power compensation is- the voltage regulation, increased system stability, better utilization of machines connected to the systems, reducing system losses associated with the system. The DSTATCOM (Distribution Static Compensator) is a device used to control the flow of reactive power in distribution systems. A DSTATCOM is a fast response device that provides flexible voltage control at the point connection to the distribution feeder for reactive power compensation. The performance of the DSTATCOM depends on the control algorithm. So, for this, there are various control algorithms are used. This paper presents study of the reference current generation technique through decoupled current control i.e, p-q theory by using voltage source converter based DSTATCOM for reactive power compensation. Reference currents generated by control technique have been tracked by the compensator in a hysteresis band control scheme. The models of DSTATCOM with HCC (hysteresis current controller) are developed and simulated in MATLAB using Simulink. It is observed that DSTATCOM is effective in compensating reactive power. Index Terms—DSTATCOM, Voltage Source Converter, Reactive Power Compensation, Distribution system, Decoupled current control (p-q theory), Hysteresis current controller (HCC).
