研究目的
To describe the wind resource and present a method for reducing wind data to a useful mathematical form, and to present a simplified theory of wind turbines leading to a basic understanding of the characteristics of actual wind turbines and a prediction of electrical energy production.
研究成果
The chapter provides a foundational understanding of wind energy conversion, focusing on the wind resource and a simplified model of wind turbines. It highlights the importance of accurate wind data and statistical methods for predicting wind turbine performance and energy production. The Betz limit is introduced as a theoretical maximum efficiency for wind turbines. The chapter concludes by emphasizing the need for further study in more complex aspects of wind energy not covered.
研究不足
The model is considerably simplified, assuming incompressible and frictionless steady flow, an ideal rotor, a nonrotating wake, and static pressure in the stream tube far upstream and downstream of the rotor equal to the undisturbed static pressure. Real-world complexities such as aerodynamics of turbine blades, mechanical aspects of gear trains and tower structures, and environmental impacts are not discussed.
