The pillar you are talking about is called a tower.
The position of the tower is determined by selecting a micro-site before installation. The position can be adjusted appropriately before installation. The aim is to maximize the efficiency of electricity production and not affect local normality (e.g. avoiding the road). , Villages, etc.);; After installation, it cannot be moved. It is very difficult to disassemble it. Generally, it won't move unless there is a gold mine or valuable dinosaur fossils underneath.
The length of the tower, each wind turbine model has one or more tower lengths. The length of the tower directly affects the height of the fan: the higher the height, the greater the air suction capacity. However, the higher the height, the corresponding parameters such as the rigidity of the tower must also be improved accordingly. . Likewise,once the tower model is selected, the length is also determined. Once installed, it will produce electricity until it is decommissioned. During the service process, the length of the tower will not be changed unnecessarily.
You’re welcome.
When the wind turbine rotates at high speed, the blade can be considered as a circular surface of radius L. After a time t, it is equivalent to a wind column of length vt striking the circular surface.
Volume of the air column (wind volume)
V=Svt=πL^2Vt
Mass of the air column m=ρπL ^2Vt
