Application and analysis of hydraulic wind power generation technology

With the increasing installed capacity of wind power, higher requirements are put forward for the quality of wind power, but the randomness and intermittency of wind power seriously affect its quality and the stability of the power grid. Hydraulic wind power technology replaces the original gearbox with flexible transmission, which can effectively absorb wind speed pulsation and impact, smooth power transmission, reduce grid impact, as well as have the advantages of reducing cabin weight and construction cost to meet the needs of large-scale wind power development. However, how to further improve the overall efficiency of hydraulic wind turbine and wind power quality needs further research and exploration. This paper comprehensively summarizes the configuration, hydraulic transmission system, pitch control, hydraulic energy storage, etc., as well as analyzes the development of hydraulic wind turbine.
