Abstract :
This paper focuses on power quality improvement with DSTATCOM on a small, isolated 42.5 kVA alternator feeding a three-phase, three-wire distribution system. Some power quality aspects like power-factor correction, voltage regulation and load balancing of linear load are discussed and implemented using DSTATCOM. DSTATCOM is realized using a three leg IGBT based PWM-VSI bridge having a DC bus capacitor. A hysteresis rule based carrier-less PWM current controller is used to derive gating pulses for the IGBT switches. The models are developed and simulated in MATLAB using Simulink and Power System Blockset (PSB) toolboxes. It is observed that DSTATCOM is effective in compensating reactive power and improving the power quality of the distribution system
