Abstract

In recent years, many wind turbine generation systems (WTGSs) have been installed in many countries from the viewpoint of global warming, for example, for reducing CO2 emissions. However the wind turbine generator output basically fluctuates due to wind speed variations. Therefore, the annual energy production depends on the wind speed characteristic of each area. This paper presents a method to calculate the loss, power, and efficiency of WTGS with doubly fed synchronous generator (DFSG), in which the wind speed characteristic is expressed by a weibull distribution function. The annual energy production and capacity factor of the wind farm can also be obtained by the proposed method. The coefficients of weibull distribution function given by local area wind energy prediction system (LAWEPS), NEDO, have been used in the analyses of this study.
