摘要/Abstract

摘要： 海上风电场集电拓扑优化是一个大规模非凸、非线性优化问题，难以求得最优解，将其分解为分区内部拓扑优化及馈线路径优化两部分：在分区内部以经济性为目标函数，在考虑海缆选型的情况下得到最优拓扑方式；在馈线部分，针对海缆交叉问题，考虑到风机实际建设工程约束，提出了分区规则化方案，借助改进Dijkstra算法实现了从传统线-线交叉判断到线-面交叉判断的转变，避免了跨立实验无法判断海缆交叉的情况。最后，以海上风电场作为算例，将所提算法与其他算法拓扑结果进行对比，验证算法的可行性及优越性。

Abstract: The topology optimization of power collection in offshore wind farms is a large-scale non-convex and nonlinear optimization problem, for which it is difficult to obtain the optimal solution. It is therefore divided into two parts: internal topology optimization and feeder path optimization. Inside the partition, the optimal topology mode is obtained by taking economy as the objective function with consideration of submarine cable selection. In the feeder part, aiming at the submarine cable crossing problem, a partition regularization scheme is proposed with consideration of the actual construction engineering constraints of the wind turbines. By using the improved Dijkstra algorithm, the transition from the traditional line-line intersection judgment to the line-surface intersection judgment is realized, and the situation that the crossover experiment cannot judge the submarine cable crossing is avoided. Finally, a case study of two offshore wind farms is studied and the proposed algorithm is compared with other topological results, which has proved the feasibility and superiority of the proposed algorithm.

Key words: large-scale offshore wind farm, collection system, topology optimization, feeder, improved Dijkstra algorithm
