The electrical energy consumed by operating vehicles includes the electrical energy consumed by train operation, the electrical energy consumed by trains entering and exiting the depot, and the electrical energy consumed by train testing and experimentation. The electrical energy consumed by power lighting equipment includes equipment systems that provide a good riding environment and ensure the safe and normal operation of the station, lighting system equipment in the commercial area of the station, and lighting equipment required for the operation unit's office. Among them, traction electrical energy consumption generally accounts for about 20% of the total energy consumption, and 80% is the electrical energy consumed by other power lighting equipment.
