摘要
当前冷热电联产系统多采用蓄能装置(如蓄能水箱)调节用户冷热日负荷的变化,但对于季节性负荷的峰谷差却没有很好的调节方法.针对这一问题,建立以燃气轮机为原动机的冷热电联产系统,利用回热器和蓄能水箱构建两级调峰系统,实现对日负荷和季节性负荷的同步调节.计算分析表明,在满足用户全年各时段冷热负荷的前提下,燃气轮机实现了全年满负荷发电,并且系统的节能效果也有所提高.
At present,the storage device （such as the energy storage tank） is often used to ad- just the change of the user＇ s heating and cooling daily load in Combined Cold Heat and Power System （CCHP） ,and there are no good methods to adjust the change of the seasonal load. In order to solve the problem,the two levels of peak system, which consists of a regenerator and a storage tank, are built for the CCHP based on the gas-turbin. Then the synchronous adjustment of daily load and seasonal load is achieved. The analysis results show that the gas-turbine generates electric- ity throughout the year and the energy saving effect of CCHP is improved considerably.
