Calculation Method of Losses and Efficiency of Wind Generators
نویسنده
چکیده
In the recent years, many wind turbine generation systems (WTGS) have been installed in many countries. However the electric power obtained from wind generators is not constant due to wind speed variations. The generated electric power and the loss in WTGS change corresponding to the wind speed variations, and consequently the efficiency and the capacity factor of the system also change. In this chapter, methods to evaluate the losses and output power of wind generator systems with Squirrel-Cage Induction Generator (IG), Permanent Magnet Synchronous Generator (PMSG), and Doubly-fed Induction Generator (DFIG) are explained. By using the presented methods, it is possible to calculate the generated power, the losses, total energy efficiency, and capacity factor of wind farms quickly.
