What is wind turbine power curve?

The wind turbine power curve shows the relationship between the wind turbine power and hub height wind speed. It essentially captures the wind turbine performance. Hence it plays an important role in condition monitoring and control of wind turbines.

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 are the roles of wind power curve modeling?

The roles of wind power curve modeling are analyzed from four perspectives: wind power forecasting, wind turbine condition monitoring, wind energy potential estimation and wind turbine selection.

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 do wind power curves contribute to wind power forecasting?

Wind power curves mainly contribute to wind power forecasting, wind turbine condition monitoring, estimation of potential wind energy and wind turbine selection. These are now discussed. 2.1. Wind power forecasting Accurate prediction of wind power is critical to increasing the utilization of wind in the electricity grid.

Can power curve copula modelling improve wind turbine performance?

Wind turbine condition monitoring by use of power curve copula modelling is suggested in [10, 11] and is a topic of further research. Early recognition of the emerging faults and timely repair and maintenance of the equipment can help in improving the performance of wind turbines.
