基于（）分析理论，建立了太阳能辅助燃煤发电系统性能分析评价模型，并以太阳能辅助某330 MW亚临界燃煤机组为例，对该辅助发电系统在燃煤节省型和功率增大型两种运行模式下的性能进行分析，结果表明，辅助发电系统在两种运行模式下其性能均优于单纯燃煤机组，且燃煤节省型辅助发电系统性能优于功率增大型。在此基础上，分别以设备的损、效率与损系数为指标，对燃煤节省型辅助发电系统与单纯燃煤机组的设备耗散状况展开研究，揭示系统的能量损失分布规律，结果表明，太阳能这一辅助能源引入单纯燃煤机组，使设备总损由448.95 MW 减少为435.15 MW、总损系数由57.76%减少为56.49%；单纯燃煤机组引入太阳能，削弱了能量在利用过程中的贬值，使系统对能量的利用效果得到改善，同时也表明了用分析方法对设备性能进行分析更有意义。

Based on exergy analysis theory, models which can evaluate the performance of solar aided coal-fired power generation system were built. The performances of solar aided a 330MW unit in two operation modes (Fuel Saver and Power Booster) were analyzed for example. The results show that the performance of solar aided coal-fired power generation system of both operation modes is superior to coal-fired unit and performance of Fuel Saver is better than Power Booster. On this basis, the equipment performances of Fuel Saver and coal-fired unit were analyzed with equipments’ exergy loss, exergy efficiency and coefficient of exergy loss as indexes and the energy loss distribution of systems were derived. The results show that the total exergy loss of equipments decreases from 448.95MW to 435.15MW and the total coefficient of exergy loss decreases from 57.76% to 56.49% because of solar energy. Introducing solar energy into coal-fired unit reduce energy quality loss, improving the energy utilization of system. It is more meaningful to analyze the equipment performance using exergy analysis theory.
