摘要/Abstract

摘要： 海上升压站选址对风电场投资成本起到关键作用。提出一种海上升压站最佳位置的确定方法。首先，根据海上风电场与陆上集控中心之间的最短距离，确定海上升压站离岸最近点。然后，根据各台风机位置坐标，通过重心法求取海上风电场的重心。随后，连接海上升压站离岸最近点与海上风电场重心，沿着其间直线移动，利用改进Prim算法确定海上风电场集电线路布局，求取增加的中压海缆距离和减少的高压海缆距离，并检验中压海缆电压压降。结合海缆成本和建设条件要求，寻求海上升压站的最佳站址。结果表明，所提出的方法简单可行，经济合理。

Abstract: Site selection of offshore substation plays a vital role for wind farm investment cost. This paper presents a method for optimal substation site selection for offshore wind farms substation. Firstly, the nearest offshore point of an offshore wind farms substations is determined by the shortest distance between the offshore wind farm and the onshore centralized control center. Then according to the position coordinates of each wind turbine, the gravity point of the offshore wind farm is obtained by the gravity method. Subsequently, a straight line is obtained by connecting the nearest offshore point of the offshore substation to the gravity point of the offshore wind farm. Next the substation site is moved along the straight line, and the layout of the current collection system the offshore wind farm is determined by improved Prim algorithm. Then the increased distance of the medium voltage submarine cable and the decreased distance of the high voltage submarine cable are calculated, and the voltage drop of medium voltage submarine cable is checked. Finally, combining the cost of submarine cables and the requirements of construction conditions, the optimal site of the offshore substation is obtained. The results show that the proposed method of this paper is simple, feasible and economically reasonable.

Key words: offshore substations, optimal site selection, the cost of submarine cables
