摘要:

摘要:自由流风速是风电机组功率曲线评估、出质保验收和后期健康运行等环节中的重要参数。传统方法是利用测风塔进行测试,存在测试周期长、测试成本高和施工难度大等缺点,特别在复杂地形中无法进行有效的测试。参考IEC 61400-12-1—2015标准,利用测量精度高、测量范围广和安装方便的激光雷达测风仪制定一套适合复杂地形风电机组自由流风速的测试方法。利用机载式雷达测风仪对复杂地形自由流风速进行不同距离的测试,根据分象限的风速变化趋势可判断自由流风速,用地面式激光雷达测风仪可验证数据的准确性和可信度。依托云南某风电场的实际案例进行试验,试验结果显示本文所采用的测试方法是可行的。

Abstract:Free stream wind speed is one of the most important parameters of wind turbine generator power curve evaluation, postwarranty acceptance and operation. Traditional method is to use anemometer tower with the drawback of long test term, high test cost and difficult construction, especially in complex terrain. Based on IEC 61400-12-1—2015 standard, utilizing of high accuracy, wide range and easy to installation laser radar anemoscope, a series of free stream wind speed measure method that suit for complex terrain was indicated. After taking tests of free stream wind speed by airborne radar anemoscope in different distance, free stream wind speed can be determined based on wind speed variation trend. The accuracy and reliability of wind speed can be verified by land laser radar anemoscope. Based on the experiment carried out in a wind power plant in Yunnan, the test method is effective.
