6 FAQs about [Graphic diagram of wind power generation output curve]

What is the power curve of a wind turbine?

Content may be subject to copyright. Typical wind turbine power curve : the turbine begins to operate at the cut-in speed v c , then the power output increases with wind speed following a cubic curve until wind speed reaches the rated speed, where the turbine begins to operate at its rated power.

How can power curves be used to monitor wind turbine performance?

Power curves can be used for monitoring the performance of turbines. For this, a benchmark curve which represents the performance of a normally operating turbine is required. This reference curve can be extracted from measured power output and wind speed data of wind turbines.

What is the power curve of a pitch regulated wind turbine?

Typical power curve of a pitch regulated wind turbine. The power curve of a WT indicates its performance. Accurate models of power curves are important tools for forecasting of power and online monitoring of the turbines. A number of methods have been proposed in various works to model the wind turbine power curve.

How can wind power output be modelled?

The probabilistic nature of wind power output can also be modelled by deriving curves using actual data of power output and wind speed of turbines deployed in a wind farm. This method requires a large number of historical data but results in accurate models [4, 24].

How does a wind turbine generate power?

It is clear from a typical wind turbine power curve, shown in Figure 4, that at very low wind speeds, the torque generated by the turbine blades is insufficient to rotate the rotor. As the speed increases, the wind turbine starts to rotate and generates electrical power.

How effective is a wind turbine power curve versus instantaneous wind speed?

Results demonstrate effectiveness of the proposed method. The power curve of a wind turbine describes the generated power versus instantaneous wind speed. Assessing wind turbine performance under laboratory ideal conditions will always tend to be optimistic and rarely reflects how the turbine actually behaves in a real situation.
