By the end of 2013,the new capacity of wind power is 16.1 GW,and the total in-stalled capacity is 91.42 GW,to maintain global leadership,but a lot of wind turbines are not in-tegrated into grid at present which is the outstanding problem. Non-grid-connected wind power system means that the terminal load is no longer a single traditional grid,but can be directly ap-plied to a series of high energy-consuming industries and other special areas which adapt to the characteristics of wind power. Based on many preliminary investigations,the demonstration project of wind power water electrolysis hydrogen production system(120 Nm3/d)was built us-ing a 30 kW wind turbine and a 10 kW wind turbine in Dafeng City,Jiangsu Province. The pow-er supply system for hydrogen production is based on non-grid-connected wind power mode. Wind power is connected to the power grid but not integrated into power grid,and seamlessly complement wind power with grid power,which gets to 100%utilization of wind power. The results reveal the coupling laws between large-scale non-grid-connected wind power and water electrolysis process.%2013年中国风电新增装机容量为16.1 GW，累计装机容量为91.42 GW，两项指标均居世界第一，却有大量风机不能并网发电。当前，并网难已成为我国大规模风电发展中的突出问题。非并网风电是指风电系统的终端负荷不再是传统的单一电网，而是通过必要的技术创新与集成，直接应用于一系列能适应风电特性的高载能产业及其他特殊领域。在江苏大丰市建成日产120 Nm3非并网风电电解水制氢系统示范工程。该系统利用1台30 kW风机和1台10 kW风机共同给电解水制氢装置供电，采用非并网风电供电模式，风电联网不并网，消除了风电对电网的冲击，实现风电100%高效、低成本利用。该系统的研究可以揭示风电与电解水制氢工艺之间的耦合规律。
