Site yield at 180 m height

Map of site yield for a fictional wind turbine (WEA) with rotor diameter of 148 m and rated power of 5 MW at 180 m height above ground. The power curve of WEA has only a certain validity range of relevant wind parameters, such as turbulence intensity, inclined flow and wind shear. In reality, however, these validity ranges are exceeded at many locations. For example, increased turbulence occurs especially in forest sites or too dense placement of WEA. Therefore, a flat-rate deduction of approx. 6 % is recommended when using the site yield.某虚构风力发电机组（WEA）的场址发电量分布图，该机组转子直径148米，额定功率5兆瓦，安装高度为地面以上180米。该风力发电机组的功率曲线仅在特定的相关风力参数范围内有效，例如湍流强度、斜向气流以及风切变。但在实际场景中，诸多场地的风力参数已超出该有效范围。例如，林地场景或风力发电机组布置过于密集时，湍流强度往往会升高。因此，在使用该场址发电量数据时，建议按统一比例扣除约6%的发电量。
