根据天然气热电冷系统运行的特点,建立了一个考虑投资、燃料价格、供热和供冷效益的成本分析模型,模型反应了产热和产冷的收益,计算出的发电成本能客观地揭示天然气热电冷系统的经济性。对影响GTCC、CCHP和BCHP经济性的主要因素,如投资、天然气的价格、机组效率和的负荷率等进行了全面分析和研究,并得出了提高经济效益的模式。
According to the operation characteristics of natural gas thermoelectric cooling system, a cost analysis model considering investment, fuel price, heating and cooling efficiency is established. The model reflects the benefits of heat generation and cooling. The calculated power generation cost can objectively reveal the natural gas The economy of the thermoelectric cooling system. The main factors influencing the economy of GTCC, CCHP and BCHP, such as investment, natural gas price, unit efficiency and load ratio, are analyzed and studied comprehensively, and the mode of raising economic benefits is obtained.
