摘要：
As traditional shore power can't supply the docked ship with uninterruptable power and can't scheduled by the power management system on the ship, a novel control strategy was presented based on virtual synchronous generator. The equations of mechanical movement for the generator was introduced into the inverter control circuit, and the second-order electro-mechanical transient model of the generator was used by introduction of the rotational inertia J in the model. The power frequency controller module and the excitation controller module which can achieve the droop characteristic of system were introduced so that the inverter side of the shore power supply possessed the output droop characteristics similar to that of the diesel generator. The simulation model of the shore power supply was built in MATLAB/Simulink and the parallel operation with the diesel generator system was simulated, the influence of the rotational inertia in the model was analyzed. And the control strategy is verified. ©, 2015, Editorial Department of Electric Machines and Control. All right reserved.
