摘要
户内变电站不同功能房间电气设备散热特性差异大,而设备散热是形成房间通风空调负荷的主要构成部分,本文首先分析了变电站的设备散热特性和环控需求,采用TRNSYS软件对典型户内变电站进行了全年动态负荷计算,分析了主要功能房间的动态负荷特性。然后以通风空调系统供需高效匹配运行为目标,通过动态负荷计算与分析,对通风空调设备选型、控制策略和免费冷利用提出了节能设计方法。最后以北京地区某110kV典型户内变电站为例,对选用节能设计方法和常规设计方法确定的设计方案进行比对分析,节能设计方案具有较好的节能减排效益。
The heat dissipation characteristics of electrical equipment in different functional rooms of indoor substations vary significantly,with equipment heat dissipation constituting the primary component of ventilation and air-conditioning loads in these rooms.First,this paper examined the characteristics of equipment heat dissipation and environmental control requirements in substations,and adopted the software TRNSYS to calculate the annual dynamic loads of typical indoor substations and analyze the dynamic load characteristics of the main functional rooms.Second,with efficient matching between the supply and demand and operation of ventilation and air conditioning systems,an energy-efficiency design method was proposed regarding the selection,control strategy,and free cold utilization of ventilation and air-conditioning equipment,through the calculation and analysis of dynamic loads.Last,a case study of a typical 110 kV indoor substation in Beijing was conducted,to compare and analyze the design schemes determined with the energy-efficiency design method and conventional design methods.The results indicated that the energy-efficiency design scheme demonstrated notable advantages in terms of promoting energy conservation and emission reduction.
