摘　　要：针对太阳能不稳定性等缺陷从而对电网的冲击,为使太阳能得到合理充分大规模的利用,该文提出一种耦合太阳能与压缩空气的燃气轮机冷热电联产系统。建立联产机组的稳态模型,分析冷热电联产系统的典型变工况特征;讨论耦合太阳能的压缩空气储能系统对燃气轮机冷热电联供系统的影响,并将联产系统应用于宁夏某交通枢纽进行案例分析,结果表明:耦合太阳能的压缩空气系统系统的引入提高三联供系统的一次能源利用率,缓解需求侧及负荷侧能量不匹配的问题,相比于传统CCHP联产机组,平均能量利用率提高6.86%,具有显著的节能效果。In order to reduce the impact of the instability and discontinuity of solar energy on the power grid and make the solar energy be used reasonably and fully on a large scale,a kind of coupled solar energy and compressed air cogeneration system of gas turbine cold,heat and electricity is proposed in this paper.The steady-state model of the cogeneration unit is established and the typical variable-condition characteristics of the cogeneration system are analyzed.The influence of the compressed air energy storage system coupled with solar energy on the cold,heat and power supply system of gas turbine is discussed,and the application of the system to a traffic hub in Ningxia is analyzed.Results shows that the introduction of the coupled solar energy compressed air system improved the primary energy utilization rate of the three-supply system,and alleviated the problem of energy mismatch between the demand side and the load side.Compared with the traditional CCHP unit,the average energy utilization rate increased by 6.86%,with significant energy-saving effect.
