On Nov 13, CRRC's first offshore wind turbine rolled off the production line in Sheyang, Jiangsu province. Focusing on the goal of optimal KWH cost in the whole life cycle of the project, the unit is a regional customized offshore wind turbine carefully developed on the basis of offshore parity, modular design and advanced research and development platform.


The offshore wind turbine, developed by CRRC Zhuzhou Institute, has achieved full coverage of 8-12MW power class. The diameter of the impeller reaches 225 meters, and its sweeping area is about 40,000 square meters, equivalent to about 5.6 standard football fields. The platform products can be developed and configured according to the specific conditions of different sea areas, so as to achieve the optimal return rate for customers and the lowest KWH cost in the whole life cycle. This unit has efficient power generation performance, at the rated wind speed, each rotation can generate 22 degrees of electricity, a single unit can output about 50 million degrees of clean electricity per year, according to the normal electricity consumption of ordinary households, a single unit can meet the annual electricity demand of about 25,000 households, can reduce 14,600 tons of coal consumption and reduce 36,500 tons of carbon dioxide emissions. It has very significant efficiency of energy saving and emission reduction. The unit adopts a series of advanced technologies and optimal design concepts such as efficient power generation blade design, lightweight semi-direct drive structure, high fault-tolerant electrical system, box change overhead, integrated hoisting, in-engine rail inspection robot, etc., and is committed to becoming a parity tool of Chinese offshore wind power.


"Driven by the global green low-carbon transition and China's dual-carbon goals, CRRC, as the central enterprise representative in the field of wind power equipment, to accelerate the development of offshore wind power equipment is a significant strategic measure to implement the dual-carbon strategy, service industry development needs, and to expand and strengthen the CRRC wind power industry. The production of CRRC offshore wind turbines further expands the product spectrum of CRRC wind power industry and fills the technical gap in the offshore wind power sector." "Said Shao Renqiang, chief economist of CRRC.


As one of the earliest enterprises to enter the wind power industry in China, CRRC has extended the advanced technologies accumulated in the rail transit industry to the new energy industry in line with the principle of "relevant diversification, high-end positioning, resource support and industry leadership", and successfully applied the key core technologies of rail transit system integration, converter and control to the wind power, photovoltaic and comprehensive energy business. It has formed the advantages of the whole wind power industry chain from the core components such as generator, blade, tower barrel, gear box, converter, super capacitor, variable propeller system to resource development, project EPC, whole machine manufacturing, intelligent operation and maintenance, and built the solution capability of the wind power whole life cycle system. In 2021, CRRC ranked first in China in terms of wind turbine sales, second in terms of blade sales, third in terms of tower sales, and fourth in terms of newly installed onshore wind turbines.



In the future, CRRC will continue to implement the national strategy of "carbon peak, carbon neutral" and "Marine power", and take this unit offline as a new starting point for CRRC offshore wind power industry to set sail. We will continue to give full play to the core technology of "devices, materials and algorithms" and the advantages of CRRC wind power industry chain, continue to promote the technological innovation of ultra-large capacity offshore wind turbines, continue to provide customers with the best quality products and services, and establish CRRC manufacturing's "golden card" brand in the field of offshore wind power. For the high quality development of Chinese offshore wind power industry, it will contribute "CRRC technology", "CRRC product" and "CRRC plan".


Relevant leaders of Sheyang County, partners such as State Power Investment, China Huaneng, China Energy Construction, Power China, Nangao, SKF, CRRC Industrial Development Department, Zhuzhou Institute, Zhuzhou Electric Machinery, Time New Material, Jiangsu Electric Machinery and project construction units participated in the downline ceremony.

11月13日,中国中车首台海上风电机组在江苏射阳正式下线。该机组聚焦项目全生命周期度电成本最优的目标,以海上平价为基础,基于模块化设计和先进研发平台而精心研制的区域定制化海上风电机组。


该款海上风电机组由中国中车株洲所牵头研制,实现了功率等级8-12MW的全覆盖,叶轮直径达到225米,其扫风面积约4万平方米,相当于约5.6个标准足球场。平台化产品可根据不同海域的特定条件,开展区域定制化的开发配置,实现客户收益率最优和全生命周期度电成本的最低。此机组拥有高效的发电性能,在额定风速下,每转动一圈可发电22度,单台每年可输出约5000万度清洁电能,按照普通家庭正常用电,单台机组每年发电可满足约2.5万户的用电需求,可减少1.46万吨的燃煤消耗以及减少3.65万吨的二氧化碳排放,具有非常显著的节能减排效益。机组采用高效发电的叶片设计、轻量化的半直驱结构、高容错性的电气系统、箱变顶置、集成式吊装、机舱内轨道巡检机器人等一系列先进技术和成本最优设计理念,致力于成为我国海上风电的平价利器。


“在全球绿色低碳转型和我国双碳目标的驱动下,中国中车作为我国风电装备领域的央企代表,加快海上风电装备研制,是落实双碳战略、服务行业发展需求,把中车风电产业做大做强的重大战略举措。中国中车这次下线的海上风电机组进一步扩展了中车风电产业的产品型谱,填补了海上风电领域的技术空白。”中国中车总经济师邵仁强表示。


作为中国最早进入风电行业的企业之一,中国中车本着“相关多元、高端定位、资源支撑、行业领先”的原则,将在轨道交通产业积累的先进技术向新能源产业延伸,成功将轨道交通的系统集成、变流及控制等关键核心技术平移应用于风电、光伏及综合能源业务。形成了从发电机、叶片、塔筒、齿轮箱、变流器、超级电容、变桨系统等核心部件,到资源开发、项目EPC、整机制造、智能运维等风电全产业链优势,构建了风电全生命周期系统解决方案能力。2021年,中车风电发电机销量排名国内第一,叶片销量排名国内第二,塔筒销量排名国内第三,风电整机陆上新增装机排名国内第四。



未来,中国中车将持续贯彻落实国家“碳达峰、碳中和”和“海洋强国”战略,以该机组下线作为中车海上风电事业扬帆启航的新起点。不断发挥“器件、材料、算法”内核技术以及中车风电全产业链的优势,持续推进超大容量海上风电机组技术创新,持续为客户提供最优质的产品和服务,在海上风电领域树立起中车制造“金名片”的品牌,为我国海上风电行业高质量发展积极贡献“中车技术”“中车产品”和“中车方案”。
