一种用激光方法改进风机对风精度的研究

Research on Applying Laser to Improve Accuracy of Wind Turbine and Wind

功率曲线是风力发电机组的设计依据,也是考核机组性能、评估机组发电能力的一项重要指标。结合目前已经出现的功率曲线问题的综合分析来看,风机对风精度是影响功率曲线的关键因素之一。现今的风机基本都是利用风向标来进行风机对风。文章通过对现在大量使用的风向标与风机找零方式进行分析研究,提出了一种不受天气、光线影响,更加精确、方便的风向标与风机之间的找零方法,提高了风机对风精度,大大改善了风机的功率曲线。

The power curve is the design basis of wind turbine, which is also an important index of assessing performance and power generation of wind turbine. According to the comprehensive analysis of power curve problems, accuracy of wind turbine and wind is the key of influencing power curve. Nearly all of the recent wind turbine use wind vane to adjust wind turbine and direction of the wind. This article analyses and researches the way about adjusting wind turbine and direction of the wind, puts forward a method of adjusting wind turbine and direction of the wind which won＇t be affected by the weather and light, but more accurate and convenient than before, thus, it improves the accuracy of wind turbine and optimizes the power curve.
