基于分布式能量系统的双源系统作为一个独立运行的冷热供应系统,可以缓解夏季城市电力供应紧张而燃气供应却相对过剩的结构性矛盾。本文基于单耗分析理论,分析了燃气轮机双源系统的运行特性及其与建筑物冷热负荷相匹配的整体特性。分析认为:燃气轮机双源系统应用于冷热负荷有鲜明时间特性的大型公共建筑,可以保证其发挥最大的能源利用效率。尤其是在夏季空调负荷高峰期,双源系统可以很好地起到削峰作用,这对优化能源消耗构成有重要意义。 As a stand-alone hot and cold supply system, the dual-source system based on distributed energy system can ease the structural contradictions that the electricity supply in summer is short and the gas supply is relatively surplus. Based on the theory of unit consumption analysis, this paper analyzes the operating characteristics of gas turbine dual-source system and its overall characteristics that match the cooling and heating load of buildings. The analysis shows that: The dual-source system of gas turbine is applied to large-scale public buildings with distinctive time characteristics of hot and cold load, which can ensure its maximum energy efficiency. Especially at the peak of summer air-conditioning load, dual-source system can play a good role in cutting peak, which is of great significance to optimize the composition of energy consumption.
