高寒地区变电站典型建筑冷热负荷特征

Cooling and Heating Load Characteristics of Typical Building for Converting Station in High Altitude Cold Region

建设绿色节能变电站是我国电力行业的一项重要任务,其中确定变电站建筑的采暖空调需求是变电站节能的核心内容之一。为了确定变电站采暖空调负荷需求状况,以高海拔寒冷地区3个变电站典型建筑为分析对象,基于实地调研基础数据和DeST软件模拟方法,对3个变电站典型建筑冷热负荷的全年动态变化特征进行模拟分析,确定负荷指标并给出出现相互差异的原因。模拟分析得出的结果将为高海拔寒冷地区变电站建筑的节能设计提供一定的指导。

Construction of green energy-saving converting station is one important task for the power industry in China. Moreover,determining the heating and cooling load of converting station building is one of the core content for energy efficiency. In order to determine the demand of heating and cooling load in converting station,as to the analysis object of three typical converting stations in high altitude and cold region,their annual dynamic heating and cooling characteristics are analyzed based on the data of field investigation and DeST software simulation. Meanwhile,the heating and cooling load index are determined and the reasons of load difference are expounded. The research results provides some guidance for energy-saving design of converting station buildings in high altitude and cold region.
