【摘要】：為了克服架空線路載流量計算時將太陽輻射強度視為定值的缺陷,充分挖掘導線潛在的輸送能力,首先以100 W/m~2的太陽輻射強度為梯度,討論了太陽輻射強度取值對不同截面導線載流量計算的影響;然后,基于大氣對太陽輻射的衰減規(guī)律,引入輻射衰減系數(shù),建立太陽輻射強度的實時計算模型,該模型可根據(jù)不同地區(qū)的經(jīng)緯度以及具體時刻,將太陽輻射強度的計算轉化為太陽射線穿過大氣層厚度的計算,達到評估某地區(qū)實時太陽輻射強度的目的;最后,結合山西大同地區(qū)2012年的氣象監(jiān)測數(shù)據(jù)和IEEE 738—2006提供的方法,對所提模型的準確性進行了檢驗,發(fā)現(xiàn)模型計算的太陽輻射強度與實際測量值基本吻合,最大誤差在70 W/m~2以內,且文中方法比IEEE方法更接近監(jiān)測數(shù)據(jù),更能滿足架空線路載流量計算的要求.
[Abstract]:In order to overcome the defect that the solar radiation intensity is regarded as a fixed value in the calculation of overhead line load, the potential transmission capacity of the wire is fully excavated. Firstly, the solar radiation intensity of 100 W / m ~ 2 is taken as the gradient. The influence of the solar radiation intensity on the calculation of the carrying capacity of different cross-section conductors is discussed. Then, based on the attenuation law of atmospheric radiation to the sun, the radiation attenuation coefficient is introduced, and the real-time calculation model of solar radiation intensity is established. The model can be calculated according to the latitude and longitude of different regions and the specific time. The calculation of solar radiation intensity is transformed into the calculation of the thickness of solar radiation through the atmosphere to evaluate the real time solar radiation intensity in a certain area. Finally, combined with the meteorological monitoring data of 2012 in Datong area of Shanxi Province and the method provided by IEEE 738-2006, the accuracy of the proposed model is verified. It is found that the solar radiation intensity calculated by the model basically coincides with the actual measured value, and the maximum error is less than 70 W / mm2, and the method in this paper is closer to the monitoring data than the IEEE method. More can meet the overhead line load capacity calculation requirements.
