太阳能系统性能的计算机模拟,分为稳态和瞬态两种。稳态程序的气象数据是月平均值,瞬态程序的数据是当地小时值。国际上稳态程序的代表是FGHART(f-图法),瞬态程序是TRNSYS。前者是1700多条的互交式(又称问答式)小型程序包,后者是10000多条的大型程序包。经过几年的工作,西北工业大学太阳能科研组已调试、运行了这两个程序包,对TRNSYS还添加了自己编写的新部件,本文只介绍瞬态模拟。 TRNSYS大型太阳能系统瞬态模拟计算机程序已有十几个版本,涉及光热、光电两大类,包括集热器、泵、蓄热器、辅助加热器等几十个常用部件,能模拟热水、采暖、制冷空
The computer simulation of solar system performance is divided into two types: steady state and transient. The meteorological data of the steady state program is the monthly mean value and the data of the transient program is the local hour value. The representative of the international steady state program is FGHART (f-graph method) and the transient program is TRNSYS. The former is more than 1,700 interactive (also known as question and answer) small packages, which are more than 10,000 large packages. After several years of work, the Solar Energy Research Team of Northwestern Polytechnical University has debugged and run these two packages. New components have been added to TRNSYS. This article only describes transient simulations. The TRNSYS large-scale solar energy system transient simulation computer program has been more than 10 versions, involving two major categories of photothermal and photovoltaic, including collectors, pumps, heat accumulators, auxiliary heaters and dozens of commonly used components to simulate hot water. , heating, cooling air
