光热电站太阳能资源典型年选取方法及验证的探讨

Discussion on the Method Selection and Verification for Typical Year of Solar Energy Resources in Solar Thermal Power Plant

太阳能光热资源典型年数据是光热电站设计的关键输入资料,它直接影响光热电站系统参数、运行指标及工程造价。本文对比分析了国内行业标准DL/T 5158—2012《电力工程勘测气象规范》太阳能资源评估中代表年与国外典型气象年(typical meteorological year,TMY)的选取方法,以某光热电站为例,通过对比塔式和槽式两种发电系统的逐年理论发电量,验证两种典型年选取方法的适用性。

The typical annual data of solar thermal resources is the key input data for the design of solar thermal power plant,which directly affects the system parameters,operation indexes and project cost of solar thermal power plant.In this paper,The method selection of radiation representative year from the DL/T 5158—2012 Technical Code for Meteorological Survey in Electric Power Engineering in domestic industry standards and typical meteorological year(TMY)abroad are compared and analyzed.Taking a solar thermal power station as an example,the applicability of the two selection methods are verified by comparing the annual theoretical power generation of solar power tower and parabolic trough solar power generation systems.
