【摘要】 目前陆上风电高风速资源日趋稀缺，在低风速区域大幅提高风电机组的塔筒高度能够充分利用高空风能资源，大幅提高平均发电量，对我国中、东部低风速区域发展风电清洁能源有着积极意义。而传统大吨位起重机安装作业方式不利于超高风电塔筒的安装。针对这一难题，文中研制了超高钢混风电塔筒自提升液压系统，将液压提升器集群作为起重机械，以钢绞线作为索具，通过传感检测和智能控制算法，确保同步提升高差小于5mm，依次将混凝土内塔筒和中塔筒提升到位，高质量地实现了某170m高的风电钢混塔筒的安装。液压自提升技术作为一种新颖的超高钢混风电塔筒的安装技术，其高度、质量不受限止，自动化控制程度高，技术可行、安全可靠。更多还原

【Abstract】 Currently, the high wind speed resources of wind power on land are increasingly scarce. Increasing the tower height of wind turbines in low wind speed areas can make full use of high-altitude wind energy resources and greatly improve the average power generation, which is of positive significance to the development of clean energy such as wind power in low wind speed areas in central and eastern China. However, the installation and operation mode of traditional large-tonnage crane is not conducive to the installation of ultra-high wind tower. Considering this difficulty, a design of self-lifting hydraulic system for ultra-high steel-concrete wind tower is proposed in this paper. In this design, the hydraulic lifter cluster is used as lifting machinery, and the steel strand is used as rigging. Through sensing detection and intelligent control algorithm, the synchronous lifting height difference is ensured to be less than 5 mm, and the concrete inner tower and the middle tower are lifted in place in turn, so as to realize the accurate installation of a 170 m high steel-concrete wind tower. Hydraulic selflifting technology is a novel installation technology of ultra-high steel-concrete wind tower, which is not limited by height and quality, has high degree of automatic control, and is feasible, safe and reliable.更多还原
