환경하중을 고려한 3MW급 해상풍력 구조물의 정적 해석

Abstract

This paper is on static analysis of 3MW class offshore wind turbine according to recent development of new and renewable energy. Static analysis was carried out considering diverse offshore environmental loads including wind load acting on tower, thrust load occurring from rotation of blade, weight of nacelle, blade and tower having greater effect with formation of MW class wind turbine, wave load, and current load at maximum loads. Underwater jacket and tower above water were designed with 3-dimensional drawing in this paper. As a result of considering offshore environment design conditions, the turbine was verified as safe because maximum stress is generated within elastic region. This paper is expected to be used as basic data for designing offshore wind turbine on environmental load at domestic sites.
