Abstract

In recent years, many wind turbine generation systems (WTGSs) have been installed in many countries from a point of view of grobal environment due to CO2 emission. But wind turbine generator output and annual energy production are dependent on wind characteristic of each area and a kind of WTGS. Authors' previous paper presented the analyses about annual electrical energy production and capacity facotor of WTGS for each area with different wind data. This paper presents a method to calculate each cost of WTGS component such as drive train system, generator and other equipments, and also to evaluate generation cost obtained from WTGS cost and annual electrical energy production. Based on these results, the optimal kind of WTGS can be determined for each installation area from an economical point of view.
