6 FAQs about [China Metro Energy Storage System]

How can Tianjin Metro save energy?

This can be attributed to Tianjin Metro's energy-saving renovation of the old stations and the adoption of efficient equipment at the new stations, such as LED lighting, high-performance air conditioning systems, and energy management systems. All these measures are also recommended for the energy conservation of metro stations in other cities.

Are metro systems energy-saving?

Against the background of energy saving and emission reduction, energy-saving technologies of metro systems have been applied to metro design, and energy-saving awareness has been implemented in actual metro operation.

How to achieve energy saving on Metro weak current system?

To achieve energy saving on metro weak current system, we conducted an in-depth research and analysis on metro energy load classification and energy management, focusing in particular on the design and usage of power supply systems for metro weak current electromechanical systems.

What is a metro power supply system?

The metro power supply system mainly includes the external power supply, main substation, step-down substation, traction substation, train traction power supply system, station power lighting power supply system and power monitoring system. The main power systems include the traction power supply and lighting power supply systems.

How do metro companies manage energy consumption?

Some metro companies have set up an energy management platform to monitor and record metro energy consumption, analyze the collected basic data, manage energy quotas and implement cost accounting, which requires correcting waste behavior to improve the economic benefits of enterprises.

How metering is used in power supply circuits?

By setting different metering instruments for power supply circuits, the main energy consumption data are collected to meet the requirements for graded metering of metro energy consumption, and then the energy consumption quota for the station weak current system is reasonably predicted.
