摘要
为了更加高效的利用高空风能,作为绿色清洁能源之一的风力发电,朝着风电机组单机容量越来越大、承载基础的塔筒建设高度越来越高的趋势发展。传统锥筒式全钢塔筒逐渐被预应力混凝土-钢组合塔筒所取代。预应力混凝土-钢组合塔筒兼具混凝土塔筒及钢塔筒两者的优势,具有承载力高、稳定性好、运输施工维护方便、建设成本低等特点,以适应较高高度风电场的需求,代表了未来风电塔筒结构发展的方向。由于高空风载荷大、风电机组的偏心载荷大等不利因素,导致提升过程中产生大弯矩和扭转的工况。因此,导向问题已成为预应力混凝土-钢组合塔筒建设中需要首先解决的技术难题。针对这一难题,创新研制了超高钢混风电塔筒导向液压系统,结合传感检测和智能控制算法,克服上述不利因素,依次将混凝土内塔筒和中塔筒提升到位,高质量地实现了国内陆上最高的国家电投鲁阳170 m高的风电钢混塔筒的安装。
In order to more efficiently utilize high-altitude wind energy,wind power generation,as one of the green clean energy sources,is developing towards a trend of increasing the single-machine capacity of wind turbines and the height of the tower structure that carries them.Traditional conical all-steel tower structures are gradually being replaced by pre-stressed concrete-steel composite tower structures.The pre-stressed concrete-steel composite tower structure combines the advantages of both concrete and steel tower structures,with characteristics such as high bearing capacity,good stability,convenient transportation,construction and maintenance,and low construction costs,making it suitable for higher altitude wind farms,and representing the direction of future wind power tower structure development.Due to factors such as high wind loads at high altitudes and large eccentric loads on wind turbines,large bending moments and twisting loads will be generated during the lifting process.Therefore,the issue of guidance has become the first technical challenge that needs to be solved in the construction of pre-stressed concrete-steel hybrid towers of wind turbine.To address this issue,this paper innovatively develops a hydraulic guidance system for ultra-high steel-concrete hybrid tower of wind turbine,which,combined with sensing and intelligent control algorithms,overcomes the above-mentioned unfavorable factors,successively lifts the concrete inner tower and middle tower into place,and installs the highest steel-concrete tower structure on land in China,the State Power Investment Corporation Luyang 170-meter-high wind power tower structure,with high quality.
