光伏电站设计中辐照度数据选用规律的研究

Study on the Selection Law of Irradiance Data in the Design of Photovoltaic Power Plants

论述了国内设计院获取辐照度数据主流方法的原理、特点及适用性,对不同地区已投运项目的实测辐照度,根据国标对比各主流方法辐照度数据的准确性。综合文献综述和实例计算分析,提出关于辐照度数据获取的各主流方法适用规律,为行业内新能源工程设计和运维管理提供依据。

This article discusses the principle,characteristics and applicability of the mainstream methods of obtaining irradiance data in domestic design institutes,compares the accuracy of irradiance data measured from projects that have been put into operation in dif⁃ferent regions according to national standards.Based on the comprehensive literature review and example calculation analysis,the mainstream methods of irradiance data acquisition are proposed to provide a basis for the new energy engineering design and operation and mainte⁃nance management in the industry.
