Abstract

An optimal layout condition of the offshore wind turbines is studied by using the response surface analysis which is a kind of the design of experiments. Based on the assumption that total 36 turbines would be installed in the offshore wind farm, the number and distance of the rows and columns are used as the design variables and the efficiency decrease of power generation due to the wake decay by the interactions of turbines and the installation cost of the internal electric grid are considered as the objective functions of the response surface analysis for the layout design of turbines. Useful design information can be derived by analyzing the relationship between the design variables and target functions. It is found that the row number and the distance between rows should be minimized, and the optimal distance between columns should be estimated and adopted to the layout design within the specified design range in order to ensure the economics for the offshore wind farm.

해상풍력단지 설계과정의 일환으로 실험계획법의 일종인 반응표면분석법을 이용하여 풍력터빈의 최적 배치조건을 연구하였다. 총 36기 터빈을 해상에 설치한다는 가정 하에 터빈들의 행렬조합, 행간 및 열간거리를 반응표면 분석시의 설계변수로 사용하였으며, 터빈 후류손실에 의해 저하되는 발전효율과 내부 전력선 공사비를 목적함수로 고려하였다. 이러한 설계변수와 목적함수간의 관계를 이용한 반응 최적화 분석을 통해 목표 설계조건을 도출하였으며, 해상풍력단지의 경제성을 확보하기 위한 풍력터빈의 배치조건은 "설계범위에서 행수 및 행간거리를 최소화하고, 최적 열간거리를 산정하여 적용해야 한다"는 결과를 얻을 수 있었다.
