内燃机分布式供能企业经济运行研究

Research on Economic Operation of Distributed Power Enterprise of Internal Combustion Engine

为有效评价分布式供能企业运行的经济性,以内燃机分布式供能企业为研究对象,在满足客户冷热需求的前提下,建立了边际效益系数计算模型。通过计算不同运行模式下的边际效益系数,可有效确定不同条件下内燃机分布式供能企业的经济运行模式。案例分析表明,在实际运行中,并非所有运行工况下选择内燃机溴化锂机组联产供能的运行模式均为最好。当冷热负荷增加时,应选择边际效益系数最大的生产模式增产;当冷热负荷减小时,应选择边际效益系数最小的生产模式减产。

In order to effectively evaluate the economy of distributed power enterprises,this paper takes distributed power enterprises of internal combustion engine as the research object,and establishes the calculation model of marginal benefit coefficient under the premise of satisfying the cold and hot needs of customers.By calculating the marginal benefit coefficient under different operation modes,the economic operation mode of distributed power enterprises of internal combustion engine under different conditions can be effectively determined.The case study shows that in the actual operation,the operation mode of internal combustion engine-lithium bromide unit is not always the best choice in all operating conditions.When the heat and cold load increases,the production mode with the maximum marginal benefit coefficient should be selected first,and when the load reduces,the production mode with the minimum marginal benefit coefficient should be first selected.
