Abstract

최근 전 세계적으로 화석에너지와 관련된 기후변화 및 국제 정세로 인해 풍력발전에 대한 관심이 증대되고 있다. 일반적으로 풍력발전 시스템은 설치 후 약 20년간의 사용연한을 갖도록 설계되며 따라서 장기간 운전할 경우, 경년화로 인한 발전 성능의 저하가 필연적으로 발생된다. 본 논문에서는 풍력발전기의 경년화와 관련된 성능 저하의 문제를 해결하기 위한 새로운 형태의 자동 튜닝 기법을 제안하고자 한다. 또한 제안된 기법의 유용성을 확인을 위해 다양한 형태의 시뮬레이션 고 찰을 수행하였다. Recently, concern over climate change and global politics associated with traditional fossil fuel energy sources has driven significant increase in wind energy utilization over the past decade around world. Generally, life-time of wind turbine system should be guaranteed for twenty years. Therefore, performance deterioration of wind turbine system occurs owing to aging effects for long term operation. In this work, a new type of auto tuning algorithm for overcoming the problem of performance deterioration is proposed. Furthermore, various simulations are carried out to verify the feasibility of the proposed scheme.
