利用WAsP软件对风力机发电量的预测

The forecast of energy production of wind turbine based on WAsP

提出了一种利用WAsP软件准确求解风力机发电量的方法。首先,利用WAsP OWC Wizard工具对欲安装风力机地区一年的风速资料进行分析,得到风谱图;其次,在给定地区的数字地图上建立模拟风力机站;然后,根据风力发电机的功率特性,采用WAsP Turbine Editor工具拟合输出功率特性曲线;最后,通过实例详细阐述风力机发电量的计算方法。由于这种计算方法完全建立在风场风谱图和风力机自身输出特性的基础上,因此得到的风力机发电量的计算结果更加准确。在WAsP软件的协助下,计算过程可以得到很大简化,能够满足工程的应用。

This paper put forward an accurate method of calculating energy production of wind turbine based on WAsP.First,the wind atlas was obtained through the analysis of the wind velocity data for selected wind turbine regions by using WAsP OWC Wizard tools.Then the simulated wind turbine station was established on the digital map of a given area.Furthermore,the power characteristic of wind turbine can be derived by WAsP Turbine Editor Tools.Finally,an example of using wind turbine to calculate the relative statistics is provided to better explain the method.As this method is fully based on the power characteristics of wind turbines and the wind atlas of wind farms,the result is more precise and reliable.With the help of WAsP software,the calculating process can be simplified to satisfy the engineering application.
