用单纯形法对冷热电三联供系统用于办公楼宇时冬夏季典型日负荷下的运行策略进行优化，优化目标分别为系统的一次能源消耗量最小、运行成本最小和二氧化碳排放量最小，并对冷热电联产系统和分产系统进行了比较。结果表明：不同优化目标下，系统的运行策略不同。冬季工况下，以一次能源消耗量最小为优化目标时，系统多采用以热定电的运行模式；在以运行成本最小或以二氧化碳排放量最小为优化目标时，系统全天采用以电定热的运行模式；以三者加权最小为优化目标时，系统多采用以热定电的运行模式。夏季工况下，以一次能源消耗量最小为优化目标时，分产系统的运行策略要优于联产系统；在以运行成本最小或以二氧化碳排放量最小为优化目标时，系统全天采用以电定热的运行模式；以三者加权最小为优化目标时，系统多采用以热定电的运行模式。

The simplex method was used to optimize the operation strategy of the combined cooling heating and power (CCHP) system under typical loads of winter and summer days when the system was used in office buildings,the optimization goals were smallest primary energy consumption,lowest running costs and lowest carbon dioxide emissions. The CCHP system was compared with the traditional system. For different optimization goals,a different operation strategy was adopted. In winter,when smallest primary energy consumption was taken as optimization goal,in more time the system ran with the mode of heating deciding power. When lowest running costs or lowest carbon dioxide emissions was taken as optimization goal,all day the system ran with the mode of power deciding heating. When the minimum of the three indicators combined was taken as optimization goal, in more time the system ran with the mode of heating deciding power. In summer,when smallest primary energy consumption was taken as optimization goal,the traditional system was better than the CCHP system. When lowest running costs or lowest carbon dioxide emission was taken as optimization goal,all day the system ran with the mode of power deciding cooling. When the minimum of the three indicators combined was taken as optimization goal,in more time the system ran with the mode of cooling deciding power.
