中文摘要:
      热电三联供系统可以同时提供冷、热、电能源,具有很好的经济性和环保性。为了提高系统运行的经济性,研究了系统在有无蓄能装置的情况下,满足四季不同能源需求的最经济的运行模式。此外,在考虑用户用能需求不确定性及电价波动的情况下,对冷热电三联供系统运行过程中的电价及运行小时数进行灵敏度分析,得到系统经济运行的区间。通过定量化的运算,得到在实际运行中,根据电价或用户具体的能源需求情况选择合适的系统。通过对三联供系统进行经济性评价和灵敏度分析,得出带蓄能装置的系统,不仅能够满足用户全年不同时段的用能需求,而且经济性最佳。
英文摘要:
      The CCHP system can provide with cold, thermaland electric power simultaneously, which has good economic and en.vironmental protection.However, due to the great fluctuation of us.ers at different periods, the system can not operate at rated power allday, and the system can not meet the user's demand fully, it makesCHHP can not have a good economical efficiency.In order to betterplay the operation efficiency and improve the economy of the sys.tem, the research has considered the peak valley price based on theCCHP system, and research about the optimal configuration of thesystem.In addition, the research considered the uncertainty of theusers demand and the fluctuation of the electricity price, also thesensitivity analysis of the electricity price and the operation hours ofCCHP system is carried out.Finally the paper gets the interval ofsystem economic operation.By quantifying operations, uses canchoose the right system based on the price of electricity or the user'sspecific energy needs in actual operation.The research analyzes theoperation economy and sensitivity of the CHHP.It is concluded thatthe system with energy storage device can not only meet the user'sdemand for energy consumption in different periods of the year, butalso provide the best economic results.
