摘要:

天然气分布式能源系统具有靠近用户,能量梯次利用,低碳、高效、清洁、环保等特点。分布式能源系统可为用户夏季供冷、冬季供暖、提供生活热水、生产蒸汽、电力等多种形式的能源。以某医药产业园为研究对象,提供一种冷热电蒸汽联产系统,通过负荷分析给出装机配置,并对联供系统进行经济性分析和敏感性分析。结果表明,售电价与蒸汽价与系统经济性有正线性相关的关系,静态投资和天然气价与系统经济性有负线性相关的关系,建立售冷热电价格与天然气价格的联动机制有利于提高项目经济性,降低项目的运行风险。

Abstract:

The distributed energy system driven by natural gas has the characteristics of being close to users, energy echelon utilization, low carbon, high efficiency, clean and environmental protection. Distributed energy system can provide users with various forms of energy such as cooling in summer , heating in winter, domestic hot water, steam and electricity. Taking a pharmaceutical industrial park as research object, it provides a kind of cogeneration system combined cooling,heating, power and steam. Installed configuration is given through the analysis of load, economic analysis and sensitivity analysis on the cogeneration system. The results show that there is a positive linear relationship between electricity price , steam price and system economy, while static investment , natural gas price have a negative linear correlation with system economy.Establishing a linkage mechanism between the price of cold,hot,electricity and the price of natural gas is conducive to improving the economic efficiency and reducing the operating risk of the project.
