【摘要】：随着经济的飞速发展，当今社会的能源危机不断加剧，兼具有节能环保、能源综合效率高、经济性好等优点的冷热电三联供系统在世界范围内受到广泛的关注。本文以典型的冷热电三联供系统为研究对象，以传统的分供系统为参照对象，将系统优化作为主线，探讨了热跟随和电跟随两种运行模式下联供系统的经济性、节能性和环保性，并将同时考虑了此三方面的综合性能评价指标作为目标函数，对五个典型气候区办公建筑的联供系统进行优化，探讨我国不同地区办公建筑应用联供系统的特点。首先，本文依据公共建筑节能标准对我国气候进行分区，将办公楼作为典型建筑类型进行研究，利用能耗模拟软件DeST对五个典型气候区代表城市（北京、哈尔滨、上海、昆明、广州）的办公楼模型进行全年逐时冷热负荷模拟，利用面积指标法进行全年逐时电负荷计算。其次，在确定了联供系统和分供系统的组成之后，分别对两种供能系统进行能量流平衡以及设备负荷与效率约束，提出从经济、能效和环保三方面对系统进行评价，并选取适用于联供系统的评价指标。然后，以北京办公楼为例，结合其全年逐时冷热电负荷数据，对联供系统在热跟随和电跟随两种运行模式下的设备容量进行配置，并对两种不同运行模式下系统的运行状况和系统的经济、能效、环境指标进行分析。最后，以驱动设备的容量为变量，，以最大综合性能评价指标为目标函数，运用Matlab软件对联供系统进行优化编程，输入五个地区办公楼建筑全年8760小时的冷热电负荷数据，求解出五组最优驱动设备容量值。根据优化结果，对不同地区办公建筑联供系统的性能进行比较，得到冷热电三联供系统在我国不同气候区办公楼建筑中的应用特点。
[Abstract]:With the rapid development of economy, the energy crisis in today's society is becoming more and more serious, and the cold, heat and electricity triple power supply system with the advantages of energy saving and environmental protection, high energy efficiency and good economy has been widely concerned in the world. This paper takes the typical cold, heat and electric power supply system as the research object, takes the traditional power sharing system as the reference object, takes the system optimization as the main line, and discusses the economy of the combined power supply system under the two operation modes of heat following and electricity following. Energy saving and environmental protection, and the comprehensive performance evaluation index of these three aspects is taken as objective function to optimize the joint supply system of office buildings in five typical climate areas. This paper discusses the characteristics of the joint supply system for office buildings in different regions of China. Firstly, according to the energy saving standards of public buildings, the climate of our country is divided, and the office building is studied as the typical building type. Five representative cities of typical climate areas (Beijing, Harbin, Shanghai, Beijing, Harbin, Shanghai) are represented by the energy consumption simulation software DeST. Kunming, Guangzhou) office building model is used to simulate the annual hourly cooling and heat load, and the area index method is used to calculate the annual hourly electric load. Secondly, after determining the composition of the co-supply system and the split-supply system, the energy flow balance and the equipment load and efficiency constraints of the two energy supply systems are carried out respectively, and the evaluation of the system is put forward from the aspects of economy, energy efficiency and environmental protection. And select the evaluation index suitable for the joint supply system. Then, taking Beijing office building as an example, combined with its year-round hourly cooling and thermal load data, the equipment capacity of the power supply system under the two operation modes of heat following and electricity following is configured. The operation condition of the system and the economic, energy efficiency and environmental indexes of the system under two different operation modes are analyzed. Finally, taking the capacity of the drive equipment as the variable and the maximum comprehensive performance evaluation index as the objective function, the combined power supply system is optimized and programmed by using Matlab software, and the data of the cooling and heat power load of the office buildings in five regions are inputted for 8760 hours a year. According to the optimization results, the performance of the combined power supply system of office buildings in different regions is compared, and the application characteristics of the system in office buildings with different climatic regions are obtained.
