The power in the wind is given by the following equation: Power (W) = 1/2 x ρ x A x v 3. Thus, the power available to a wind turbine is based on the density of the air (usually about 1.2 kg/m 3), the swept area of the turbine blades (picture a big circle being made by the spinning blades), and the velocity of the wind.
We can now determine how yearly energy production from a wind turbine relates to average wind speeds. The graph on the right was created by inputting data into the power calculator from the previous page and then plotting the results against the power curve for the default example, a 600 kW wind turbine.

6 FAQs about [Calculation method of annual wind power generation]
How to calculate the cost of a wind turbine?
Economical Analysis of the Data One of the most important studies that have to be carried out while establishing a wind turbine to a region is the calculation of kWh power cost. Generally, the cost of one wind power project per kWh is found by proportioning the annual total cost to the annual power generation amount.
How do you calculate the power of a wind turbine?
The power in the wind is given by the following equation: Power (W) = 1/2 x ρ x A x v 3 Thus, the power available to a wind turbine is based on the density of the air (usually about 1.2 kg/m 3), the swept area of the turbine blades (picture a big circle being made by the spinning blades), and the velocity of the wind.
How is wind speed calculated?
This is in line with our expectations, as wind speed is calculated to the power of 3 in the wind power equation (see (1)). However, in order to examine the influence of the wind turbine configuration on the results, further analysis is required with a larger deviation between the turbine design.
How to calculate the output power of a wind turbine?
Multiplying these two values produces an estimate of the output power of the wind turbine. Below you can find the whole procedure: 1. Sweep area of the turbine. Before finding the wind power, you need to determine the swept area of the turbine according to the following equations: For HAWT: A = π \times L^2 A = π × L2 For VAWT:
How to calculate wind power potential?
The results in section 4 focus on the differences in the calculated power generation. Thus, in the following section, we give an overview of the wind power potential calculation and the underlying equations. The power output P of a wind turbine can be calculated as follows [ 29 ]: (1) P = 1 2 ⋅ ρ ⋅ A ⋅ c p ⋅ v w 3
How accurate are wind turbines' annual energy production (AEP) estimates?
Accurately estimating wind turbines' annual energy production (AEP) is a paramount for planning and performance assessment of wind power projects. Inaccurate estimates during the planning phase could result in lower/higher project economic feasibility. This leads to financial consequences in the project’s contractual agreement.
