摘要
提高大电网自愈能力、优化波动性能源备用、发挥输电设备利用率是未来输电网架结构规划的3个关键问题.首先讨论美国"Grid 2030"直流异步互联电网结构;介绍欧洲"Super Grid 2050"广域可再生能源电网结构;论证中国"三北"可再生能源电网远景设想的必要性和可行性,并给出2020,2030,2050年这3个时间节点的可再生能源电网目标网架;最后探索特高压电网结构应用于超/特高压直流电网的优势.
Improving self-healing ability, optimizing fluctuation energy reserve, increasing trans- mission facilities efficiency are three key issues of future transmission backbone planning. First- ly, US ＂Grid 2030＂ power transmission backbone is discussed in this paper. By introducing EU ＂ Super Grid 2050＂ power transmission backbone, the necessity and feasibility of renewable energy power grid in Northwest China, North China and Northeast China are demonstrated. Also, the 2020, 2030, 2050 target networks based on the proposed structure are designed. Finally, the advantages of ultra-high voltage grid （UHV grid）used in EHV/UHV DC transmission power system are explored.
