According to the traditional control of three-phase inverter, basing on the transient mathematical model of second order of virtual synchronous generator, the three loops control of power-voltage-current with virtual synchronous generator (VSG) by using the feedback of capacitance's voltage and current was built. And the proportional and integral control was applied in the loop of voltage to ensure zero steady-state error. In the meantime, the control system has droop characteristic and virtual inertia as synchronous generator rotors. In this paper, study of the parallel operation of high frequency link three- phase matrix inverter based on virtual synchronous generator control is carried out for the first time. It will improve the capacity of the system, reduce the volume, reduce the weight, reduce the noise, and realize the combination of safety isolation and synchronous generator with large inertia, high output impedance and frequency stability. Finally, the simulation results verify the correctness and effectiveness of the research.
