| 摘要: |
| 集电系统规划是海上风电场设计的重要环节，考虑线路损耗和断路器配置对提升海上风电场的经济性与可靠性具有重要意义。建立了线路损耗预估模型，确定线路最优选型；基于线路带风机数量建立了适用于大规模海上风电场集电系统的规划模型；建立了线路级可靠性评估模型，使模型兼顾线路损耗与可靠性优化。以某装机容量为375 MW的海上风电场为例分析集电系统可靠性，结果表明线路级可靠性评估模型能有效优化集电系统断路器配置。对某装机容量为750 MW的大型海上风电场进行多升压站规划，结果表明该模型可有效降低集电系统成本，具有高效求解大型海上风电场集电系统的多升压站拓扑规划问题的能力。所提方法无须对风电场进行预设分区，具有良好的工程适用性与全局优化能力。 |

| Abstract: |
| The planning of the electrical collector system is an important part of offshore wind farm design. It is of great significance to consider the line loss and the configuration of circuit breakers to improve the economy and reliability of offshore wind farm. A line loss pre-estimation model is established to determine the optimal line selection. Based on the number of wind turbines connected to each line, a planning model suitable for large-scale offshore wind farm electrical collector system is developed. A line-level reliability evaluation model is constructed, enabling the simultaneous optimization of line losses and reliability. A 375 MW offshore wind farm is taken as a study case to analyze the reliability of the electrical collector system, and the results indicate that the line-level reliability evaluation model can effectively optimize the configuration of circuit breakers in the electrical collector system. For a 750 MW large-scale offshore wind farm, the multi-substation planning is carried out, and the results show that the model can effectively reduce the cost of the electrical collector system and has the ability to efficiently solve the multi-substation topology planning problem for large-scale offshore wind farm. The proposed method does not require pre-partitioning of wind farm and has strong engineering applicability as well as global optimization ability. |
