分布式能源系统运行效果受负荷稳定性的影响

通过分布式供能系统与普通供冷供热方案的经济性比较，定量分析了热负荷与冷负荷的变化及两者的比重对分布式能源系统运行经济性和初投资回收期的影响。研究发现，冷热负荷的稳定性对分布式能源系统运行效益影响显著，实际冷热负荷占额定冷热负荷的百分率对分布式供能系统的初投资回收期有显著影响同时，在冷热电联产中，供热所用余热比重越大，分布式供能系统的经济性越好。

The Effect of Load Stabiltiy on the Distributed Energy Supply System

Through economics comparison between the distributed energy supply system and the common system,the effect on the system economy and initial investment payback period is analyzed quantitatively,owing to the variation and the ratio of the heat load and the cooling load in the distributed energy supply system.The stability of the heat load and the cooling load has the obvious influence on the system running,the percentage of actual load to rated load has remarkable impact on initial investment payback period of the distributed energy supply system,and the greater proportion of residual heating used,the better the energy supply system.
