【摘要】：针对互联运行的分布式冷热电联产系统进行节能优化研究,在分布式冷热电联产系统网络中通过系统间的电、冷、热的互相传输,提升网络的整体节能性能.建立了两个并网运行的分布式冷热电联产系统的互联运行优化模型,该模型以总相对节能率最大为目标对系统进行运行优化.选择宾馆和写字楼的两个分布式冷热电联产系统进行案例分析,系统分别根据宾馆和写字楼的冷热电负荷进行优化设计,然后利用互联运行优化模型对其运行状态进行优化,使总相对节能率进一步提升.通过优化,该案例的总相对节能率由互联前的23.9%提升到28.5%.
[Abstract]:The energy saving optimization of distributed cogeneration system is studied, and the transmission of electricity, cooling and heat between the systems is carried out in the distributed cogeneration system network of cold, heat and electricity. To improve the overall energy-saving performance of the network. Two grid-connected distributed cogeneration system operation optimization model is established. The model takes the total relative energy saving rate as the goal to optimize the operation of the system. Two distributed co-generation systems of cold, heat and power in hotel and office building are selected for case study. According to the cooling and thermal power load of the hotel and office building, the system is designed optimally, and then the operation state of the system is optimized by using the interconnected operation optimization model, so that the total relative energy saving rate can be further improved. The total relative energy saving rate in this case increased from 23.9% before interconnection to 28.5b.
