| 摘 要： | 由于计算模型本身的限制,风能资源地图分析与应用程序(WAsP)不能准确模拟复杂地形中风的流动变化情况,用其评价复杂地形风电场的风能资源时存在一定误差.目前,主要采用RIX方法来评估WAsP在复杂地形中的风速预测误差,长期以来一直缺少根据风速预测误差来评估风电场发电量预测误差的有效方法.文章在RIX方法的基础上,对WAsP应用于复杂地形风电场发电量预测的误差进行了研究,结合工程实践提出了一种发电量误差评估方法;根据某风电场实际发电量数据对提出的评估方法进行了验证,证明其有效性和实用性.

| Abstract: | WAsP is not able to simulate the flow of wind field in the complex terrain,because of the model limitation,which induces some errors when applies it to the wind resource assessment for complex terrain.At present,the RIX method is the most popular method for error evaluation of wind speed,but how to evaluate the error of energy production,there are not any effective methods yet.This paper studies the error of calculated energy production by WAsP when it was applied to the complex terrain.An error evaluation ... |
