湿热传感器

热传感器用来测量空气温度,而湿度传感器来测量空气湿度。它们组合使用用来降低成本。空 气湿度的计算不会对风点评估有直接的影响,但是知道这个参数可以帮助评估测量地点因为结冰而存在的潜在危险。温度传感器应该总是被架设在至少10米的高度 从而有足够的距离来保护它不受地球辐射的影响。

  

Impact of Measurement Errors on AEP Calculation

Temperature and air pressure significantly affect the AEP (Annual Energy Production). Hence, according to IEC 61400-12-1 temperature and air pressure have to be measured in a wind measurement campaign.

Wind power is linear proportional to the invers of temperature 1/T (in Kelvin). At 15°C, 1°C error on temperature measurement induces 0.35% error on AEP. The standard IEC 61400-12-1 specifies the relation where the sensitivity factor for temperature is cT,i Pi / 288.15 K.

Therefore IEC 61400-12-1 requires measuring air pressure and temperature.

The impact of humidity on AEP might be significant if air temperature is high. At sea level and at air temperature of 20°C, air density varies 1.2% between 0 … 100% humidity. It varies 2.0% at 30°C and 4% at 40°C. At high temperatures the IEC recommends to measure the humidity, as well.
