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。

By the end of 2013，the new capacity of wind power is 16.1 GW，and the total installed capacity is 91.42 GW，to maintain global leadership，but a lot of wind turbines are not integrated 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 applied 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 using a 30 kW wind turbine and a 10 kW wind turbine in Dafeng City，Jiangsu Province. The power 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.
