摘要
冷热电三联供系统可以为用户同时提供冷、热、电能源,具有很好的经济性和环保性。由于用户不同时段的用能波动很大,系统不能全天都按照额定功率运行,也不能完全满足用户的用能需求,不能很好地发挥其经济性。为了更好发挥系统的运行效率,提高系统运行的经济性,提出在冷热电三联供系统的基础上,探索系统在配置蓄能装置的情况下,满足四季不同能源需求的最经济的运行模式。通过结合峰谷电价等情况,计算各种方案运行所耗费的燃料成本和电费,进行经济性评价。最终得出带蓄能装置的系统,在不同季节的一天内不同时段的系统运行方案。最终的结果表明,带有蓄能装置的冷热电三联供系统可以按照额定功率工作,并且经济性最佳。
combined cooling heating and power(CCHP)system can provide users with cold,hot and electric power,which has good economy and environmental protection.However,because the use of energy of users fluctuates greatly at different periods,the system can not operate in accordance with the rated power all day,nor can it fully meet the user's energy demand,and can not give full play to its economy.In order to give full play to the efficiency of the system and improve the economy of system operation,this paper proposes the the most economical operation mode for the system with energy storage equipment to meet the energy needs of different seasons based on the CCHP system.In combination with the peak and valley price,this paper calculates the fuel cost and electricity cost of various running schemes,and makes economic evaluation.Finally,we obtain the optimal operation scheme of the system with energy storage equipment in different periods of time in different seasons.The results show that the CCHP system with energy storage equipment can work according to the rated power and has the best economy.
