小型天然气分布式供能系统的优化配置与评估

“西气东输”工程的投入运营，为沿线的众多城市与地区提供了稳定而充足的天然气资源，也为推广应用以天然气为能源的小型分布式供能系统提供了条件。通过对采用天然气的小型分布式供能系统的分析，研究了对该供能系统进行优化配置和评估的原则与方法；着重讨论了系统设计负荷的计算、机组的选择、蓄能装置的设置等因素对小型天然气分布式供能系统优化配置与运行的影响，并形成了一套相对完整的、对小型天然气分布式供能系统进行效益评估的体系，进而设计出了相应的评估软件。研究结果对于小型天然气分布式供能系统的推广应用具有一定的促进作用。

OPTIMIZED CONFIGURATION AND EVALUATION OF SMALL GAS DISTRIBUTED ENERGY-SUPPLYING SYSTEM

Since the project of “West east gas transmission” was put into operation, the stable and sufficient gas source is provided for the many cities and areas along the pipeline, and the conditions to popularize and apply the small distributed energy supplying system taking gas as energy source are offered. With the analysis of the small gas distributed energy supplying system, the criteria and method to conduct the optimized configuration and evaluation of energy supplying system are studied. And the influence of the factors such as the load calculation for the system design, the selection of the unit groups, and the establishment of the energy storing facilities etc. on optimized configuration and operation of small gas distributed energy supplying system is discussed emphatically. The completer benefit evaluation system is formed for the small gas distributed energy supplying system. The corresponding evaluation software is developed. The study achievements have a certain impact to popularize and apply the small gas distributed energy supplying system. (Financed by the Project of National Science Fund, No. 50376033)
