Abstract
The spread of wind energy converter is progressing in recent years and its capacity is becoming larger and larger. In order to capture more energy from the wind, it is important to analyze loss characteristics of wind generators for operating speed which is determined dependent on the wind speed. This paper presents a method to evaluate various losses in wind generator as a function of wind speed, which is based on the steady state analysis and thus the calculation can be performed quickly. By using the proposed method, wind turbine power, generator output, various losses, and the total energy efficiency are calculated for three types of wind speed data which are represented by a weibull function.
