Evaluation and Analysis of Energy-saving Type Energy Management System for Qingdao Metro Line 13
Journal Title: Urban Mass Transit - Year 2024, Vol 27, Issue 9
Abstract
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.
