摘要/Abstract

摘要： 海上风电场由于包含限制区域增加了集电系统拓扑结构设计的难度。为了解决此类问题,本文以集电系统设计方案电缆使用总长度最小为目标,从Delaunay三角剖分的性质出发,提出了一种改进的最小生成树算法。算法首先将限制区域顶点与风机坐标点按同质点处里生成Delaunay三角网,再将限制区域顶点作为非同质点将Delaunay三角网中的边分成两类,以海缆路径不通过限制区域为优先原则在两类边中寻找边形成最小树拓扑。最后以一个包含三个限制区域的案例海上风电场验证了所提算法的有效性。

Abstract: Constraint area increases the difficulty in the design of topology structure of offshore wind farm electrical collection system. In order to solve this problem, this paper, aiming at minimizing the total length of the cable, proposes a refined Minimum Spanning Tree algorithm based on the properties of Delaunay Triangulation. The algorithm forms the Delaunay Triangulation network with the points of wind turbine and the vertices of the constraint area, and then divides the edges of the Delaunay Triangulation network into two categories, and uses edges from two categories to form the minimum spanning tree under the priority principle that cable cannot be laid in the constraint area. Finally, the author uses the case of an offshore wind farm including three constraint areas to verify the validity of the proposed algorithm.
