摘　　要：为解决新能源规模受电网消纳能力限制问题,利用电解水制氢消纳弃风、弃光能源,是近年来解决此问题的新路径。作为电解制氢系统与电网的能源接口,提升制氢电源效率对经济效益提升有重要意义。提出了一种基于碱性电解槽电气特性,通过调节前级输出电压从而控制后级满占空比运行的模糊控制策略。首先分析了制氢电源的功率损耗。其次,通过对电解槽电气特性模型和传热模型分析,提出以消除DC/DC变换器开关损耗为目标的模糊控制策略并仿真验证。最后通过样机实验验证了该策略的损耗优化效果。In order to improve the efficiency of PWM hydrogen generation power supply,a fuzzy control strategy based on the electric characteristics of alkaline electrolyzer is proposed to control the full duty cycle operation of the rear stage by adjusting the output voltage of the front stage.Firstly,the power loss of hydrogen production power supply is analyzed.Secondly,through the analysis of the electric characteristic model and the heat transfer model of the electrolytic cell,the fuzzy control strategy aiming at eliminating the switching loss of DC/DC converter is proposed and verified by simulation.Finally,the optimization effect of this strategy is verified by prototype experiments.
