Abstract
The impact of micro scale turbulence wind speed on wind power generation is studied in this paper. The relationship between turbulence wind components and some key parameters, such as the accumulator effective volume, unit mass energy storage and state of charge, is analyzed when the micro scale turbulence wind speed is equal to the rated one. And then, a hydrostatic wind turbine system and its corresponding control method are proposed, which can not only realize the short-term energy storage, but also keep the wind turbine working under the rated power condition. Finally, aimed at a 10 kw hydrostatic wind turbine system with an accumulator to implement short-term energy storage, the simulation analysis is carried out when the micro scale turbulence intensity is 12% of the rated wind speed. The results showed that the output energy of the hydrostatic wind turbine system with a short-term storage accumulator is 11.3% larger than that of the corresponding system without accumulator.
