海上风电的大规模开发是实现“双碳”目标的重要举措之一。针对未来大规模海上风电集中开发与送出的需求，开展了风电直流直送负荷中心拓扑选取影响因素分析与构建原则研究。首先，针对海上风电送出规模扩大的背景，讨论了海上风电登陆后经直流架空线直送负荷中心的必要性。然后，从海上风电汇集方案、多端直流网络拓扑、直流故障隔离、海上换流站拓扑以及柔性直流系统受端落点方式5个方面出发，分析了大规模海上风电直流送出并网的拓扑选取影响因素，并提出海上风电直流直送负荷中心的拓扑构建原则。最后，针对某地区实际电网开展了海上风电多端直流系统的构建，证明了所提构建原则的可行性。

The large-scale development of offshore wind power is one of the key measures to achieve the "dual carbon" goals. To address the future demand for centralized offshore wind power development and transmission, an analysis of influencing factors and construction principles is conducted for the topology selection of offshore wind power direct current （DC） transmission to load centers. Firstly, against the backdrop of expanding offshore wind power transmission scale, the necessity of transmitting offshore wind power via overhead DC lines directly to load centers after onshore connection is discussed. Then, from five perspectives which are offshore wind power aggregation schemes, multi-terminal DC network topologies, DC fault isolation, offshore converter station topologies, and flexible DC system receiving-end connection methods, the influencing factors for topology selection in large-scale offshore wind power DC grid integration are analyzed. Correspondingly, construction principles for offshore wind power DC transmission to load centers are proposed. Finally, a multi-terminal DC system for offshore wind power is constructed in a specific regional power grid demonstrating the feasibility of the proposed construction principles.
