摘　　要：在对槽型抛物面集热器所吸收的有效辐射进行系统分析的基础上,改进了末端效应的计算方法,提出了以入射辐射强度(incident direct insolation,IDI)替代直射辐射强度(direct normal insolation,DNI)作为当地太阳能资源评估标准的见解.根据计算结果,以分别处于纬度29.43°N和43.47°N的拉萨市和内蒙古奈曼为例,从全年的角度来看,拉萨的DNI值超出IDI值14.33%,而纬度较高的奈曼则相差22.43%之多;从系统模拟分析的结果来看,在槽型抛物面太阳能电站选址时,采用IDI值比DNI值更加合理.The effect radiation of the parabolic trough concentrator is studied thoroughly. It was revealed that Incident Direct Insolation （IDI） should be used to evaluate the solar resource for locating a PTSTP plant, in-stead of Direct Normal Insolation （DNI）, Lhasa, with latitude of 29. 43, and Naiman, with latitude of 43.47, were studied respectively. The results indicate that Lhasa＇ s annual DNI level is 14. 33% higher than that of IDI,while it is 22. 43 higher in Naiman. The performance of a 35MW -parabolic trough solar power plant was simulated for 9 typical locations in China, and the results verified the advantage of IDI to DNI as a plant siting factor.
