摘要

为研究有限时间内热力系统换热量与热源温度对系统性能的影响及太阳能辅助燃煤发电系统集成的理论基础，对有限时间热力系统中热机输出功率和效率与循环参数的关系表达式进行了改进，并结合太阳能辅助燃煤系统案例讨论了各参数的意义及其对系统性能的影响，为系统参数的调整方向提供参考。结果表明，500和1 000 MW燃煤发电机组在系统设计上比较合理，输出效率都在C-A效率与理想循环效率之间，集成后的系统效率有所降低，1 000 MW集成系统在节煤模式下系统性能恶化，效率低于C-A效率，需要对系统过程进行改进。200 MW燃煤发电系统在集成前后效率都低于C-A效率，表明系统过程需要较大改进。

Abstract

To reveal the influence of heat transfer and heat source temperature on system performance in finite time

and the theoretical basis of solar-aided coal-fired power generation system

the relationship between output power

efficiency and cycle parameters in finite time thermodynamic system was improved. The significance of each parameter and its influence on system performance were discussed in combination with the case of solar-aided coal-fired power generation system. The results show that the system design of 500 MW and 1 000 MW coal-fired generating units is reasonable

and the output efficiency is between C-A efficiency and ideal cycle efficiency. The integrated system efficiency is reduced to some extent. The performance of 1000 MW integrated system deteriorates under the coal saving mode

and the efficiency is lower than C-A efficiency. Therefore

the system process needs to be improved. The efficiency of 200 MW coal-fired power generation system before and after integration is lower than the C-A efficiency

indicating that the system process needs to be greatly improved.
