Wind power curve of wind turbine

What is a wind power curve?

The wind power curve indicates how much power a wind turbine should produce at any given wind speed. The maximum value from the wind power curve may be used in marketing wind turbines and for comparisons between competing models, so the values are sometimes higher than the actual output.

What are the applications of wind turbine power curves?

With regards to applications, several key applications of wind turbine power curves, including wind turbine selection, capacity factor estimation, wind energy assessment and forecasting, and condition monitoring, have been discussed in Section 3.

How do you measure peak performance of a wind turbine?

One way to measure peak performance is to use a graph of a power curve. A power curve is a graph that shows the wind speed and the output power of the wind turbine over a range of wind speeds from zero to the maximum wind speed for which the wind turbine is designed. Figure 1 shows a graph of a power curve for a wind turbine.

What are the key features of a wind turbine power curve?

Key features of the power curve Wind turbine power curves typically contain the following key features: (1) Cut-in wind speed: The wind speed at which the wind turbine starts generating power. (2) Rated wind speed: The wind speed at which the wind turbine is capable of producing its rated power.
