本文研究SOFC/GT/ST三重复合动力系统。首先基于Aspen Plus建立了SOFC/GT/ST的性能分析模型,分析了各主要参数对SOFC/GT/ST复合动力系统性能的影响规律。研究结果表明:复合动力系统尽量在高的压力,温度在900℃左右的条件下,有较高系统效率;较高的燃料利用率(U_f)有利于提高系统效率。本文研究成果为开拓研究高效SOFC/GT/ST复合动力系统提供了有益的参考。
This paper studies the hybrid power system of Solid Oxide Fuel Cell(SOFC)/Gas Turbine (GT)/Steam Turbine(ST).Performance analysis model of SOFC/GT/ST hybrid system is developed based on Aspen Plus soft and the effects of main parameters on the performance of SOFC/GT/ST hybrid system are studied.The obtained results show that:SOFC/GT/ST hybrid system has the higher system efficiency at higher operating pressure and operating temperature of around 900℃;the higher fuel utilization ratio also help improve system efficiency.Above research achievements will provide valuable reference for further study on of SOFC/GT/ST hybrid power system with high efficiency.
