What are the forms of use of wind energy?

First, for wind turbines, no matter how advanced they are, their maximum utilization rate is 59.3%, which is the Bates limit (a conclusion based on aerodynamics). The maximum utilization rate of wind energy is fixed. value.

Nowadays, different wind turbines have different utilization rates. Utilization rates for large 3-blade horizontal axis wind turbines vary depending on wind size. Taking a large 1.5 mW wind turbine as an example, the rated wind speed is 13 to 16 m/s. The diameter of the wind wheel is 60-70 m, and the cp value, which is the wind energy utilization coefficient, is about 0.45. That is to say, the utilization rate is around 45%. Specific data should be based on the design plan.

For vertical axis wind turbines, the cp value is lower, that's why vertical axis wind turbines have a small market share.

If vou have questions about wind energy, you can keep asking them.

The The moment of Wind turbine voltage changes and the frequency is also unstable. Although there is a speed stabilization device inside, it cannot be directly connected to the network. The solution is to generate electricity storage conversion and connect to the grid. This is how the changing current is stored in the battery by rectification, and then the stable DC power from the battery is converted into power frequency voltage via an inverter and fed into the power grid.
