【 摘 要 】

A detailed modelling method and corresponding simulations for an all-DC offshore wind farm equipped with a permanent magnet synchronous generator (PMSG) are elaborately discussed and conducted. This all-DC wind farm is designed in series-connected topology with an offshore DC substation and a voltage-sourced converter−high-voltage direct current (VSC-HVDC) transmission system. Some major components including wind turbine, synchronous generator, VSC, and isolated full bridge converter are all modelled based on the complete electrical models and engineering parameter settings. Containing the start process of the system, the simulations under various wind speed conditions and the specific faults analysis under different situations are carried out in the MATLAB/SimulinkTM environment. Simulation results reveal the comprehensive operating characteristics of this all-DC offshore wind farm and its system response to faults.
