艾尔姆玻璃纤维公司（LM Glasfiber）日前宣布将进行一项为期三年的科研项目，旨在发展一项激光风能自动感应系统。公司该项目受到丹麦国家技术促进基金会资助支持。这项科研成果，主要针对有效提高风电叶片工作效率，相关方表示，并将这种新型叶片将被大规模应用到今后的风机系统中。

    这项计划目是为了有效提高风力发电机运载控制，由此提高涡轮机工作效率，进而促进风力发电机整体稳定性。

    “目前，LM公司正在同时进行几个科研项目，都和提高风机叶片工作效率相关，研究的目的旨在提高整体风力发电机组能源产量，其中重点部分，是发展一种新型“智能”风机叶片：这种叶片能够通过感应当前风速，将相关数据提供给风力涡轮机控制系统，并且根据当前风速自行调整到最佳转速的工作状态。”LM公司研发主管Lars Fuglsang表示说。

    这个项目主要应用了综合激光雷达（光学定向和测距）技术，同时，与LM公司现有的风机叶片检测技术相结合。通过应用这套综合系统，在风力涡轮机20年的使用寿命中，能源产量有望比现有提升5%。

    Fuglsang接着补充道：“尽管目前的风电叶片检测系统能够衡量叶片工作载荷，而应用综合激光雷达技术，能够使我们精确掌握当前风力数据。因此，我们能够随时掌握当前实时风速的第一手资料，从而使风机叶片和风力涡轮机调整为最佳工作状态。”

    LM公司预计，2012年将完成首台利用综合激光雷达技术的风机样本，2014年将投入量产并接受客户预定。

LM Glasfiber has entered into a three-year research project, supported by the Danish National Advanced Technology Foundation, to develop laser-based wind sensory systems, which the partnership hopes will enhance blade efficiency and become an integral part of all future wind turbines.
The project aims to significantly improve the load control of the wind turbine in operation, therefore enhancing the efficiency of the turbine and improving its overall reliability.

“LM Glasfiber is working on several projects to improve the efficiency of the blades and consequently the overall energy production from the wind turbine. An important part of this is developing ‘intelligent’ blades that measure the wind and either adapt to the current wind conditions or supply data to the wind turbine control system,” says Lars Fuglsang, LM Glasfiber Research Director.

The project will look at integrating LIDAR (Light Detection And Ranging) technology, with LM Glasfiber’s existing blade monitoring technology.

By using these combined systems, it is hoped that energy production can be increased by anything up to 5% over the wind turbines 20-year lifespan.

“Whereas current blade monitoring technologies measure the loads on the blades, integrating LIDARs into the blade enables us to measure the exact wind conditions to which the blades are exposed. So basically, this means that instead of looking in the rearview mirror and realizing what the blade has been exposed to, we will be able to measure the wind real-time and either have the blade or the wind turbine react on this right away,” adds Fuglsang.

LM Glasfiber anticipate that a prototype using LIDAR technology will be produced by 2012 and will be in production and available to customers by 2014.
