【摘要】：针对燃气轮机冷热电联产系统在"以热定电"运行方式下可能造成的电能过剩和部分负荷时效率不高等问题,该文提出一种太阳能与压缩空气耦合储能(solar andcompressed air energy storage,S-CAES)的燃气轮机冷热电联产系统。通过燃气轮机冷热电联产系统典型变工况模型和储能系统的Aspen Plus分析模型,获得S-CAES燃气轮机冷热电联产系统的变工况特性;讨论了各子系统的变工况特性和耦合系统在不同储能率下的运行性能,比较了储能系统释气流量调节与空气透平入口温度调节两种调节方式对系统性能的影响。将S-CAES燃气轮机冷热电联产系统用于华南地区某宾馆建筑进行案例分析,结果表明:与无储能燃气轮机冷热电联产系统相比,在夏季、过渡季、冬季典型日,该系统每天分别节约能量16.57、15.94、11.87GJ;平均能量利用率分别提高5.68%、7.88%和4.69%。
[Abstract]:The gas turbine CCHP system may result in power determined by heat "mode of operation under the excess energy and part load efficiency is not high, this paper proposes a solar and air energy storage compression coupling (solar andCompressed air energy storage, S-CAES) of the gas turbine CCHP system with gas turbine. CCHP system typical variable condition model and storage system Aspen Plus analysis model, obtain the variable condition characteristics of S-CAES gas turbine CCHP system; performance characteristics of variable condition and coupling system of each subsystem in different energy storage rate under discussion, comparison of the storage system and gas flow control and air release turbine entrance temperature regulation two regulating effect on the performance of the system. The S-CAES gas turbine CCHP system for case analysis of a hotel building in Southern China area, the It shows that compared with the no energy storage gas turbine CHP system, the system saves energy 16.57,15.94,11.87GJ per day in the summer and the typical winter days in the transition season, and the average energy utilization rate is increased by 5.68%, 7.88% and 4.69%. respectively.
