Abstract


The Distribution Static Compensator (DSTATCOM) is used for development of power quality in power distribution network with various loads such as linear, nonlinear and variable load. The dc link capacitor voltage is directly affected by any alteration made in the load. Proper operation of DSTATCOM requires maintenance of capacitor voltage within the limits. Right from the beginning, conventional controller has been used to maintain the converter dc-link capacitor voltage. In spite of it, the transient response of the PI and Hysteresis controller is still slow. In this paper, an adaptive hysteresis band current controller is proposed for DSTATCOM to eliminate harmonics and compensate the reactive power of three-phase converter. The adaptive hysteresis band current controller is varied from the hysteresis bandwidth with respect to modulation frequency, source voltage, dc link voltage and slope of the reference compensator current wave. Mathematical expressions are given to design the adaptive hysteresis band current controller to achieve the fast transient response. The results of simulation study of the proposed method have been carried out using MATLAB simulation software.
