Which airport systems rely on EPS power supply during power outages?

In the event of a power outage at the airport, the systems that rely on EPS power mainly include the following aspects:

Emergency lighting system

The public area lighting in the airport terminal adopts a double-circuit cross-power supply method, when one power failure, it can still maintain 50% of the illumination in the public place. The conversion time of emergency lighting is required to be no more than 5 seconds, so the EPS power supply device is set at the emergency lighting distribution box.

Fire fighting system

Whether the power supply of fire fighting equipment needs to adopt end switching is not required in the British standard and the European standard. After the demonstration of local fire experts, it is determined that the distribution cabinet with dual power switching device is set separately for fire fighting equipment.

Electronic information equipment

There are many electronic information equipment in the terminal, and such equipment has high requirements for the continuity of power supply, usually at the millisecond level. In order to ensure that the normal operation of important electronic information equipment in the terminal will not be affected when the two-channel high voltage power supply is converted and the diesel generator set is powered off, UPS uninterruptible power supply devices are provided for the following equipment: BMS system, Data Communication Room (BD), Power Management System (PMS), Closed Circuit Television Monitoring System (CCTV), Access Control System (ACS), Clock System (MCS), Sound amplification system for flight information release (PAS), Flight Information display Device, Airport Operations Center (AOC), Automatic Fire Alarm System (FAS) Electricity consumption for equipment in the ticketing area, electricity consumption for equipment in the passport detection area, and electricity consumption for computers in some airport management and operation offices.

Baggage handling system (BHS)

More important, large-capacity and centralized equipment such as BHS, AHU(air handling unit) and domestic water pumps are separately equipped with MCC control/distribution cabinets, and the power supply is derived from the MDB low-voltage distribution cabinet.

Air traffic control system

Air traffic control has become the focus of more and more attention in various countries, once there is a failure, it will cause huge losses, and the key power system for the power supply of the ground light system in the flight area has become crucial.

Navigational lighting system

As one of the most important visual navigation AIDS, the operation of the navigational lighting system can directly affect the safety of flight, so the nature of its electrical load is a particularly important load in the first load.

Security equipment

Airport security equipment, flight information and timing devices and other electrical loads are particularly important in the first load.

CONCLUSION

These systems rely on EPS power in the event of an airport power outage to ensure the normal operation of the airport and the safety of passengers. EPS power systems play a vital role in airports, ensuring that critical equipment and systems continue to operate during emergencies.

EPS BATTERY SERIES

The centralized power supply for fire emergency lighting is a kind of backup power supply equipment, which provides power guarantee for emergency lighting equipment to ensure that the on-site lighting equipment can operate normally in emergency situations such as fire. Provide a long-term backup power supply to meet the needs of the emergency lighting system.
