Review of fluid and control technology of hydraulic wind turbines

Abstract: This study examines the development of the fluid and control technology of hydraulic wind turbines. The current state of hydraulic wind turbines as a new technology is described, and its basic fluid model and typical control method are expounded by comparing various study results. Finally, the advantages of hydraulic wind turbines are enumerated. Hydraulic wind turbines are expected to become the main development direction of wind turbines.

“…As a promising alternative to the above wind turbines, hydraulic transmission based wind turbines have the potential to overcome their shortcomings [3]. The hydraulic transmission can be varied continuously through an infinite number of ratios and this gearing flexibility enables the wind turbine to operate at a more ideal tip speed ratio and thus to enhance the power generation efficiency and cost effectiveness.…”

“…The newly developed variable speed wind turbine equipped with a permanent magnet synchronous generator eliminates the gearbox, but a full power converter is essential, and the manufacturing cost of this wind turbine is prohibitive [5]. Therefore, the highest potential for wind power generation is to remove the gearbox and power converter in the nacelle of the wind turbine and produce high quality power through the hydraulic transmission system that has many outstanding advantages such as easy variable speed control, large power weight ratio, and high reliability [6].…”

“…In recent years, the gearless wind turbine with fluid power transmissions has attracted the attention of researchers around the world because of the unique advantages of variable transmission ratio, high power density, and reliability. The use of hydraulic drives not only can remove an AC frequency converter and a voltage transformer, but also make it possible to significantly reduce the weight of the nacelle and tower [6,7]. Ayana et al established the simulation model of a gearless hydraulic wind energy harvesting and transfer system using the SimHydraulic toolbox in the MATLAB.…”
