Demonstration project of energy management system based on cloud platform for rail transit

The energy management system of Ningbo Rail Transit is based on a cloud platform, which constructs a traction side "supply use" collaborative integration technology based on bidirectional variable current traction power supply technology, permanent magnet synchronization technology, and dedicated track return current technology. It explores a new energy-saving mode for stations mainly based on ventilation and air conditioning energy-saving technology and DC lighting technology, studies the energy consumption data collection and analysis system based on the cloud platform, establishes an energy consumption standard index system covering various equipment systems and production and operation links of rail transit, and creates a national energy model line that is resource saving, green, low-carbon, intelligent and efficient.
