大规模海上风电的非并网多元化应用研究——变海上风电场输电上岸为直接输产品上岸的探索

Research on the non-grid-connected diverse application of large-scale offshore wind power—exploration on changing offshore wind power transmission into product transmission ashore

针对海上风电大规模发展成本高、并网难、故障概率高的瓶颈,提出了一种海上大规模风电非并网多元化应用系统。该系统突破海上大规模风电并网的单一应用模式,通过必要的技术创新与集成,将大规模海上风电与高载能产业(如海水淡化、电解水制氢和电解铝等)直接耦合形成一个完整的新系统,变海上风电场输电上岸为直接输产品上岸,不仅破解了大规模、超大规模海上风电应用难题,而且大幅度节省海上风电场投资成本,提高了风电利用效率,具有十分重要的现实和战略意义。

For high cost, hard grid connection and high failure probability of large-scale offshore wind power, a non-grid-connected diverse application system is proposed. Breaking the single on-grid application mode of large-scale offshore wind power, the system directly couples offshore wind power with high-energy consumption industries （such as seawater desalination, hydrogen production by water electrolysis and electrolytic aluminum, etc. ） into a new and full one through the necessary technical innovation and integration. It uses offshore wind power and changes power transmission into product transmission ashore, which not only breaks the difficult problem of large-scale, super-large-scale wind power application but also saves the investment of offshore wind farms and increases the utilization efficiency of wind energy. As a result, the system is of great practical and strategic significance.
