Abstract :
This paper presents a method to represent various losses in wind generator as a function of wind speed, which is based on the steady state analysis. By using the proposed method, wind turbine power, generated power, copper loss, iron loss, stray load loss, mechanical losses and energy efficiency can be calculated quickly. Calculation was done using a wind speed data expressed by Probability Density Function in order to predict capacity factor and total efficiency of a wind farm for one year. Finally it is concluded that the proposed prediction calculation method is effective, and can contribute to a wind generator design and construction planning of a wind farm.
