摘要
[目的]青岛地铁13号线建设方对于运营过程中的节能具有较高的要求,建设过程中为了贯彻轨道交通节能、环保、智能的理念以及实际需求,需要从地铁机电系统中寻找可以通过控制系统实现节能的切入点。[方法]通风空调是地铁的能耗大户,也是目前节能关注的重点,为此,中交第二公路勘察设计研究院有限公司针对其特点创新设置了节能型能源管理系统并成功上线运行。该系统首次打通了能源管理与环控系统风水联动节能控制之间的信息传输通道,使原本独立的两个系统可以协同运行。通过对能耗的分析、调控、管理,利用节能型能源管理系统模型与控制策略实现环控系统内风系统和水系统的联动控制,从技术上实现节能的目的。[结果及结论]在节能模式与非节能模式交替运行相同时间的情况下,对各测试车站的空调水系统和风系统能耗进行测试、记录和对比,计算得到节能型能源管理系统的节能率,以此判断节能效果完全能满足系统设计时的最低节能要求。类比设定时间段内两种运行模式下站内环境变化,确定节能型能源管理系统的运行能够保证站内环境在节能的前提下能处于稳定舒适的状态。
[Objective]The constructor of Qingdao Metro Line 13 has a higher requirement for energy saving during operation.In the process of construction,in order to implement the concept of energy saving,environmental protection,and intelligence in rail transit and meet the actual demand,it is necessary to seek entry points for energy saving through the control system in metro electromechanical system.[Method]Ventilation and air conditioning,as the key energy consumers of metro,are the focus of the present energy saving.Therefore,in consideration of their characteristics,CCCC Second Highway Consultants Co.Ltd.creatively sets up an energy-saving energy management system and successfully launches it for online operation.The system for the first time opens up the information transmission channel between energy management and air-water linkage energy-saving control of environmental control system,coordinating the two independent systems.With ana-lysis,regulation and management of energy consumption,the linkage control of air and water systems within the environmental control system is realized by using the energy-saving energy management system model and control strategy,technically achieving the goal of energy saving.[Result&Conclusion]When the energy-saving mode and the non-energy-saving mode run alternately for the same period,the energy consumption of the air conditioning water and air systems at each testing station is tested,recorded and compared,and the energy-saving rate of the above management system is calculated.Based on the results,it is concluded that the energy-saving effect can fully meet the minimum energy-saving requirements during system design.By comparing the changes in the station internal environment under the two operating modes during the set time period,it is determined that the operation of the energy-saving energy management system can ensure stable and comfortable internal environment of the station under the premise of energy saving.
