摘要

为提高能源利用效率

缓解化石能源短缺危机

以及解决散煤燃烧过程中带来的环境问题

提出了一种风-煤互补分布式能源系统

并以某化工园区为例

在热跟随运行模式下对该系统进行了热力学特性分析和参数敏感性分析。结果表明:该系统全年一次能源利用率为80.86%

?效率为47.31%

具有较好的热力学性能;系统的一次能源效率和?效率随着蒸汽需求量的增加、储能系统效率的升高而升高

随着蒸汽需求小时数的升高而降低;受风机切入、切出风速的影响

平均风速的变化也会影响分布式能源系统的热力学性能。

Abstract

To enhance the energy utilization efficiency and alleviate the crisis of fossil energy shortage and the environmental problems during the coal combustion

a novel distributed energy system integrated of wind and coal was proposed. By taking a chemical industrial park as an example

this paper analyzed the thermodynamic characteristics and parameter sensitivity in heat-following operation mode. The results show that

the annual primary energy utilization efficiency and exergy efficiency of the distributed energy system are 80.86% and 47.31%

respectively

indicating this system has a great thermodynamic performance. The primary energy utilization efficiency and exergy efficiency increases with the energy storage system efficiency and steam demand

and decreases with the increasing steam demand hours. The thermodynamic performance will also be influenced by the average wind speed considering the cut-in and cut-out wind speed.
