摘　　要：节能减排一直是世界各国持续关注的热点问题,综合能源三联供系统因其具有更高的一次能源利用率而被广泛应用。针对综合能源三联供系统的容量配置和运行模式规划问题,提出考虑[火用]损失的综合性能指标作为优化的目标函数,从高效、低碳、经济三个方面进行综合优化。以燃气轮机的容量和运行模式为设计变量,建立综合能源三联供系统容量配置与运行模式研究模型。将此方法应用到某宾馆建筑的联供系统进行分析,研究结果为:燃气轮机的最佳容量为200 kW,热电结合是最优的运行模式。在该模式下综合能源三联供系统较传统供能系统[火用]损失率降低3.5%,年综合碳排量减少593.7 t,年经济成本节约29.8万元。该方法能够全面、客观地分析某容量、某种运行模式下的系统性能,为解决联供系统的运行规划问题提供参考。Energy saving and emission reduction has always been a hot issue that countries in the world continue to care about.The triple-generation system of combined cooling,heating and power system is widely used because of its higher primary energy utilization.For the capacity allocation and operation mode planning of the combined cooling,heating and power system,a comprehensive evaluation index considering exergy loss is proposed as the objective function of optimization,and the function optimizes the system from three aspects of high efficiency,economy and low emission.Taking the capacity and operation mode of the gas turbine as design variables,the research model of capacity allocation and operation mode of triple-generation system is established.This method is applied to the co-generation system of a hotel building for analysis and planning.The research results show that the optimal capacity of the gas turbine is 200 kW,and the combination of heat and power is the optimal operation mode.Under this mode,the combined cooling,heating and power system has a 3.5%lower exergy loss rate than the traditional energy supply system;the annual comprehensive emissions is reduced by 593.7 t;the annual economic cost is saved by 298000 yuan.This method can comprehensively and objectively analyze the system performance under a certain capacity and certain operation mode,which provides a reference for solving the operation planning problems of the combined cooling,heating and power system.
