IEC TS 62862-1-2:20 17（E）定义了为太阳能热电（STE）工厂模拟创建年度太阳辐射数据集（ASR）的程序。本文件定义了ASR结构所需的程序及其组件和参数。本文件的适用范围是指与太阳能热电厂项目相关的需求，主要涉及太阳辐射总和接近正常年度值（来自所有可能年度值的估计）的年度期间的模拟。

IEC TS 62862-1-2:2017(E) defines the procedures for the creation of annual solar radiation data sets (ASR) for solar thermal electricity (STE) plant simulation. This document defines procedures needed for the ASR construction as well as its components and parameters. The scope of application of this document refers to the needs associated with solar thermal power plant projects and mainly related to the simulation of an annual period with a solar radiation sum close to a normal annual value (from among an estimation of all possible annual values).
