| Abstract: | This paper presented a new methodology for offshore wind farm grid-connection overvoltage and reactive power compensation. The methodology used DIgSILENT PowerFactory software for offshore wind farm modelling, including wind turbine, submarine cable, transformer and relevant control schemes. Moreover, dynamic simulations was performed in time-domain to analyze the active power, reactive power and voltage characteristics of the wind farm under different wind speed conditions. According to the results of the simulations, reactive power compensation devices were configured, and consequently the voltage and power factor condition of the offshore wind farm would be improved, which was also verified by the simulation results. |
