摘　　要：【目的】水电解制氢设备在运行时,电解槽出口温度是决定电解槽能耗的重要参数。当前槽温控制法是通过设定槽入口温度值来控制冷却水流量的,无法适应风电、光电制氢过程中宽功率波动的工况,有必要对其进行改进。【方法】提出一种基于AB PLC的新型槽温控制方法,该方法能将复杂的控制过程转换成温度控制功能块,用户无须知道底层逻辑,可根据设计的引脚功能关联相应变量,从而完成对槽温的控制。【结果】该方法能满足制氢设备的正常工作需求,且具有可移植性高、应用方便、集成性高等优点。【结论】测试结果表明,应用该策略的水电解制氢设备使用性能良好,在宽功率波动的工况下能实现对槽温的稳定控制,在风电和光电制氢行业中具有良好的应用前景。[Purposes]During the operation of water electrolysis hydrogen production equipment,the outlet temperature of the electrolytic cell is an important parameter that determines the energy consumption of the electrolytic cell.The current cell temperature control method is achieved by controlling the cooling water flow rate based on the set value of the cell inlet temperature,which cannot adapt to the wide power fluctuation conditions in wind power and photovoltaic hydrogen production processes,which is necessary to improve it.[Methods]Propose a new cell temperature control method based on AB PLC,which can package complex control processes into temperature control function blocks.Users do not need to know the underlying logic,and can associate corresponding variables based on the designed pin functions to complete the control of cell temperature.[Findings]This method can meet the normal working requirements of hydrogen production equipment and has the advantages of high portability,convenient application,and high integration.[Conclusions]Tests have shown that this function has good performance and can achieve stable control of cell temperature under wide power fluctuations.It has high application prospects in the wind power and photovoltaic hydrogen production industries.
