某分布式能源系统中冷热电三联产控制优化分析

对于分布式能源系统中冷热电三联产项目,面临冷热电需求之间不平衡的矛盾。本文在传统的以电定热（冷）和以热（冷）定电两种运行方式的基础上,提出通过优化控制逻辑、智能化预估算控制、优化运行方式和添加辅助设备等方式,对分布式能源系统中冷热电三联产进行了优化,并实际运用在某产业园分布式能源项目中,通过对优化前、后联产系统的总热效率进行的计算对比,验证了该方法的合理性,对同类型项目有很好的借鉴意义。

Analysis of Control Optimization for a Distributed Combined Cooling Heating and Power System

Analyses an project of distributed combined cooling heating and power system, facing the contradiction is not balanced , between cold/heat and power demand. On the basis of the two conventional operation modes ＂Heat（cool） de- termined by electricity＂and＂Electricity determined by heat（cool）＂, by means of optimizing control logic, optimizing opera- tion mode , Intelligent prediction control and adding auxiliary equipment etc., the distributed energy system of cooling heat- ing and power system was optimized, and the practical application in a industrial park in distributed projects, Comparison between calculation results on the overall thermal efficiency of such an actual system be fo re and after optimization proves the rationality of themethod, is a good reference for the same types of projects.
