Control of grid-connected wind power brine hydrogen production system

由于新疆盐碱水资源丰富,使得土地盐碱化也比较严重,因此发展新疆风电-盐水电解制氢并联产盐技术,既可以提高风能利用水平,又可以实现盐碱水资源化、能源化综合利用。该文将新型电极材料应用到电解槽,构成的宽功率电极电解槽体系产生了全新的V/I特性及功率特性,并针对各部分动力学特性进行研究。控制设计基于滑模技术,尤其是适用于控制快速开关器件,具有较强的鲁棒性。因此,尽管风力和温度不同,氢气生产效率也得到了优化。

Due to the rich saline and alkaline water resources in Xinjiang,the land salinization is also serious.Therefore,the development of Xinjiang wind-brine electrolysis hydrogen production combined with salt production technology can not only improve the utilization level of wind energy,but also realize the comprehensive utilization of saline and alkaline water resources and energy.In this paper,a new electrode material is applied to the electrolytic cell,and the wide power electrode electrolytic cell system generated new V/I characteristics and power characteristics.The control design is based on sliding mode technology,which is especially suitable for controlling fast switching devices and has strong robustness.As a result,hydrogen production efficiency has been optimized despite differences in wind and temperature.
