摘　　要：海上风电电解水制取“绿氢”,是促进新能源消纳,实现电力、化工行业深度脱碳的重要技术方向。随着海上风电制氢从输电近岸制氢向远海输氢方向转变,利用现有远海油气平台和油气管道进行海上风电集中式制氢是未来“绿氢”获取的主要方向之一。然而,由于中压高频变压器绝缘裕度小、优化设计难等问题,制约了海上风电集中式制氢装备的设计和应用。针对上述问题,文中提出一种基于模块化多电平矩阵变流器(Modular Multilevel Matrix Converter, M3C)的中频隔离型海上风电集中制氢装备,装备前级采用M3C变换器,后级采用12脉冲晶闸管整流器,实现中频隔离,避免绝缘设计困难。晶闸管的高电流应力实现大功率制氢,同时并优化设计其关键参数。最后,利用MATLAB/Simulink仿真软件搭建所提制氢装备的仿真平台,验证所提制氢装备的有效性。The production of“green hydrogen”by electrolyzing water from offshore wind power is an important technological direction for promoting the consumption of new energy and achieving deep decarbonization in the power and chemical industries.With the shift of offshore wind power hydrogen production from nearshore hydrogen transmission to offshore hydrogen transmission,utilizing existing offshore oil and gas platforms and pipelines for centralized hydrogen production from offshore wind power is one of the main directions for obtaining“green hydrogen”in the future.However,the design and application of centralized hydrogen production equipment for offshore wind power are constrained by problems such as small insulation margin and difficult optimization design of medium voltage and high-frequency transformers.The article proposes an intermediate frequency isolated offshore wind power centralized hydrogen production equipment based on Modular Multilevel Matrix Converter(M3C)to address the above issues.The equipment uses an M3C converter in the front stage and a 12 pulse thyristor rectifier in the rear stage to achieve intermediate frequency isolation and avoid insulation design difficulties.The high current stress of the thyristor enables high-power hydrogen production,and its key parameters are optimized.Finally,a simulation platform for the proposed hydrogen production equipment was built using MATLAB/Simulink simulation software to verify its effectiveness.
