【摘要】：能源供應日益緊張的今天，提高能源利用率是人們非常關(guān)注的問題，冷熱電三聯(lián)供是當前一種發(fā)展前景很好的技術(shù)，本文對別墅群采用冷熱電三聯(lián)供系統(tǒng)進行了探討。試圖分析別墅群規(guī)模對冷熱電三聯(lián)供系統(tǒng)性能的影響，找出適合別墅群采用三聯(lián)供系統(tǒng)的臨界規(guī)模。 冷熱電三聯(lián)供系統(tǒng)組成很復雜，配置形式多樣。根據(jù)別墅群內(nèi)用戶特點和能量“梯級利用原則”選擇三聯(lián)供的配置形式。以滿足別墅群內(nèi)用戶全部冷熱負荷和部分電負荷為目的。本課題對比了兩種不同的配置形式，最終確定了內(nèi)燃機與煙氣直燃機的組合形式。然后利用模擬得到別墅群的冷熱逐時負荷和常規(guī)的計算方法得到的電負荷和生活熱水負荷，為三聯(lián)供系統(tǒng)設(shè)備選型。 通過對確定配置形式的三聯(lián)供系統(tǒng)的節(jié)能性和經(jīng)濟性分析，，得到了別墅群適合采用三聯(lián)供系統(tǒng)的規(guī)模下限。然后再對發(fā)電效率、市電價格、天然氣價格等參數(shù)進行分析，得出使本課題別墅群三聯(lián)供系統(tǒng)節(jié)能、經(jīng)濟運行的參數(shù)范圍。對參數(shù)進行敏感分析時發(fā)現(xiàn)，市電價格對別墅群三聯(lián)供系統(tǒng)經(jīng)濟性的影響尤為顯著。三聯(lián)供系統(tǒng)年運行時間對系統(tǒng)經(jīng)濟性也有較大的影響，分析年運行時間對三聯(lián)供系統(tǒng)影響能為運行優(yōu)化提供依據(jù)。 三聯(lián)供系統(tǒng)在保證能源供應穩(wěn)定性方面具有良好的效果，三聯(lián)供系統(tǒng)不僅能減少電網(wǎng)在用電高峰時的壓力，還能在電力供應出現(xiàn)故障時充當應急能源的作用。 本課題的研究方法和成果可以推廣到類似用戶的三聯(lián)供系統(tǒng)，為規(guī)劃設(shè)計階段提供幫助。
[Abstract]:Nowadays, when energy supply is increasingly tight, people pay close attention to improving energy utilization efficiency, and cold, heat and electricity triple power supply is a promising technology at present. This paper discusses the use of cold, heat and electricity triple power supply system in villa group. This paper attempts to analyze the influence of villa group size on the performance of the system, and to find out the critical scale suitable for the villa group to adopt the triple power supply system. The composition of the system is very complex and the configuration is various. According to the characteristics of the users in the villa group and the "cascade utilization principle" of energy, the configuration form of triple supply is selected. In order to meet the villa group all the cold and hot load and part of the electricity load for the purpose. In this paper, two different configurations are compared, and the combination of internal combustion engine and flue gas direct gas turbine is determined. Then, the electricity load and domestic hot water load of villa group are obtained by simulation, which are used to select the equipment of the triple supply system. Based on the analysis of energy saving and economy of the triple supply system with fixed configuration form, the lower limit of the scale of the villa group suitable for the use of the triple supply system is obtained. Then the parameters such as power generation efficiency, electricity price, natural gas price and so on are analyzed, and the parameter range of energy saving and economic operation of the triple supply system of this subject villa group is obtained. The sensitivity analysis of the parameters shows that the effect of the price of electricity on the economy of the triple supply system of the villa group is particularly significant. The annual operation time of the triple-supply system also has a great influence on the system economy, and the analysis of the influence of the annual running time on the triple-supply system can provide the basis for the operation optimization. Triple supply system has a good effect in ensuring the stability of energy supply. It can not only reduce the pressure of power supply peak, but also act as an emergency energy in the event of power supply failure. The research methods and results of this paper can be extended to the similar user-like triple supply system, which can be helpful to the planning and design stage.
