摘　　要：能耗与淡水资源是制约电解水制氢发展的瓶颈问题,利用海洋能发电来制取淡水及氢气,是实现海能海用、海洋效益最大化的重要途经之一。提出一种潮流能发电制取淡水和氢气的集成技术方案。海水淡化后首先满足生活需求,冗余的淡水用于电解制氢。为验证系统方案的可行性,建立了系统模型并进行了仿真和部分试验验证,重点对发电装备的能量控制策略和制氢单元的高效能控制方法进行了研究,以60 kW潮流能发电机组单机系统为例,仿真结果表明,基于潮流能发电的制淡制氢系统具有较好的稳定性且理论上可日产淡水约90 t,同时制取氢气约55 Nm3。The energy and fresh water resources restrain the development of the hydrogen production by the electrolysis of the water.The production of the fresh water and the hydrogen by using the ocean energy can best use the marine resources.An integrated system is proposed for generating the fresh water and the hydrogen from the tidal current energy to meet the daily requirement of the fresh water and also the demand of the hydrogen produced from the water by the electrolysis.A simulation model is established to verify the feasibility of the system.The control strategy of the power generation equipment and the operation mode for high efficiency is discussed.The simulation results of a 60 kW tidal current power generator integrated with the reverse-osmosis units and the electrolyzers show that the system enjoys a good stability and can theoretically produce about 90 tons of the fresh water and about 55 Nm3 of the hydrogen per day.
