| description | The present invention relates to a thrust modeling method of a wind turbine by a tower shadow and a system therefor. More specifically, the present invention relates to a thrust dynamic load modeling system of a wind turbine by a tower shadow below a rated wind speed, comprising: a thrust calculation unit calculating a thrust value of a wind turbine blade when there is no tower shadow; a tower shadow thrust change acquisition unit acquiring a thrust value changing by the tower shadow; a tower shadow thrust change coefficient calculation unit calculating a tower shadow thrust change coefficient based on the thrust value calculated by the thrust calculation unit and the thrust value acquired by the tower shadow thrust change acquisition unit; a database making a database based on the tower shadow thrust change coefficient; and a blade thrust modeling unit modeling a dynamic load by thrust change generated on each blade by the tower shadow by using the thrust value calculated by the thrust calculation unit and the tower shadow thrust change coefficient stored in the database. The present invention is able to rapidly and efficiently model a dynamic load of a thrust change on a tower shadow.
