Abstract In this paper, a new control scheme of a proportional resonant (PR) + harmonic compensation (HC) combined with current state feedback for an Active Voltage Quality Regulator (AVQR) is proposed. The current state feedback loop is used to actively increase the damping factor to eliminate the peak amplitude at resonant frequency of LC filter system, as well as enhanced the stability of system. Meanwhile, the load current feed forward loop is implemented to compensate the voltage drop due to the state feedback loop and suppress the load disturbance. A combined PR and harmonic compensation control structure is added into the outer voltage loop to achieve zero steady-state error and compensate harmonics, which come from the source, power inverter and nonlinear load. The theory analysis and simulation of the proposed method are investigated in detail. Laboratory experiments are carried out on a single-phase 2kVA AVQR system. The simulation and experimental results verify the feasibility and effectiveness of the proposed controller.

Key words： AVQR proportional resonant control harmonic compensation state feedback digital control scheme
