Abstract :
A novel main circuit topology of voltage quality compensator (VQC) is proposed in this paper, composed of PWM rectifier and cascade H-bridges inverter. The three phase inverter is decoupling controlled. PWM rectifier is adopted to maintain the dc-bus voltage stably and provide or absorb real power. The inverter is controlled by carrier phase shifting with FPGA. The simulation model is set up on the platform of PSCAD/EMTDC, the voltage sag, swell and harmonic compensation is researched by theoretical and simulation. Finally, the simulation results show that the proposed main circuit topology and control strategy is feasible and efficient for multi objectives voltage quality compensation.
