CHP联合供能系统及其应用分析

Design and analysis of CHP system applying for the large scale electro-area

为缓解目前供电紧张的局面,很多学者和专家提出采用分布式能源供电的方式。简单介绍了新型CHP供能系统的概念和目前国内外CHP供能系统的发展情况,并且详细阐述了此系统的设计原则以及相关设备的选型等。同时为了显示CHP供能系统的优越性,以某大型医学园区为例,设计适合该园区的混合式供电系统,计算其主要经济性指标,分析其调峰能力和对某些可变经济因素的敏感性,并与常规电网进行比较。最后得出,CHP系统无论在经济性还是可靠性方面都具有很大优势,值得大力推广。

Distributed heating and power fashion are brought forward by many scholars and experts to relieve the tension of electric power supply. The concept of the new pattern CHP system is introduced in the paper, then the situation of the development of this technology in China and abroad is described. The planning principles and the selection method of devices are elaborated. To show the superiority of CHP, the most suitable CHP system of an international medical zone is designed. Its necessary economic targets are calculated and its capability to decrease the gap between the electricity peak and valley is analyzed. Its sensibility to some variable economic factors is discussed. After the comparison with the normal electrical grid, the conclusion is that CHP system is preponderant in the respects of both reliability and economical efficiency, and is worth being popularized.
