为协调热电联产中热、电负荷的变化,解决热电供需不平衡问题,对分布式能源系统中燃气轮机热电联产的运行方式进行了优化。在传统“以电定热”和“以热定电”两种运行方式的基础上,提出通过添加辅助设备的方式来补充热电联产的运行方式。通过对优化前、后联产系统的总热效率进行的计算,验证了该方法的合理性,并对热电联产子系统的运行方式提出了建议。
In order to coordinate and balance the demand of heat and power, an optimization on the operation mode of heat & power cogeneration gas turbines in a distributed energy system has been made. On the basis of the 2 conventional operation modes " Heat determined by electricity" and " Electricity determined by heat" , a new mode by adding some auxiliaries for make-up purposes is being proposed. Comparison between calculation results on the overall thermal efficiency of such an actual system before and after optimization proves the rationality of the method. Moreover, proposals for operation modes of branch heat and power cogeneration systems are also put forward.
