| Abstract |
This paper presents a directly driven wave power generation system which is connected to power gridcomposed of permanent magnetic linear generator(PMLG)， generator side converter, grid sideconverter, controller and grid. Control strategies based on back to back converter structure wasproposed: vector decoupling control was used to generator side converter aiming at optimize powerextraction from wave energy; Grid voltage oriented control was used to grid side converter in order tomake the current sinusoidal and realize unit power factor control. Since the DC link voltage hasfluctuation using traditional method, a method with power feed forward was proposed to keep the DClink voltage stable and improve the dynamic response of the system. A simulation model was built forthe whole system in Matlab/Simulink and simulation results verified that the proposed control strategyis feasible and effective. |
