The height of the wind turbine tower and the hub height are not necessarily the same. The height of a wind turbine tower usually refers to the height from the foundation to the top of the tower. This height can be set arbitrarily according to the design requirements and is not limited by the height of the hub. The hub height refers to the vertical height of the wind turbine blade center position from the ground. This height is determined by the rotation radius of the wind turbine and the height of the ground, and generally cannot be set directly.
When designing some wind farms, the comprehensive issues of tower height and hub height will be considered based on the actual terrain and wind resource conditions. When wind speed is related to height and the higher the height, the greater the wind speed, appropriately increasing the tower height can achieve higher power generation benefits. However, it is also necessary to comprehensively consider the feasibility and cost-effectiveness of the project and select the appropriate height of the wind turbine tower and hub to achieve the best power generation benefits.
