槽式太阳能热发电系统数值模拟研究

在我国西部适宜进行光热电站开发的两个地区,对典型配置的50MW槽式太阳能热发电站进行了系统顾问模型(SAM)软件和Greenius软件的数值模拟计算,主要进行了储热时长优化及月发电量、年发电量、年利用小时数、光电效率等的计算,并将两个软件的计算结果进行了对比分析。结果表明,两个软件的计算结果差异并不明显,且差异来源可能为集热场热量输出模型以及汽轮机模块。

Abstract:

In two regions suitable for the developing solar thermal power stations in western China, numerical simulation with system advisor model (SAM) software and Greenius software is made on a typical 50MW parabolic trough solar thermal power plant. The calculation is carried out mainly on heat storage duration, gross power output per month, annual gross power out, annual utilization hours, photoelectric efficiency, etc. The numerical results indicates that the results of two softwares show similar results and the difference of the results may be caused by the heating field thermal output model and the steam turbine model.
