Analysis Of The 200 Kva Power In UPS (Unintrruptible Power Scale) System at The Airport Terminal Of PT. Angkasa Pura II (Persero)

Abstract

The higher the level of electricity consumption, the PLN (State Power Plant) as a provider of electricity and
as a national electricity energy manager has the obligation to meet the national electrical energy needs
which are increasingly increasing. In order to avoid an undesirable thing, the electricity network is cut off at
the airport terminal which can endanger the safety, comfort and safety of prospective airplane passengers.
So, UPS is used as an alternative electrical energy supplier to anticipate sudden power outages while
waiting for an emergency generator to be activated (emergenci diesel generator). This report focuses on
discussing how long UPS can back up the Airport Terminal load without an emergency generator which is
done using the observation method in the field. The results of the observations in the field were found that by
using a UPS, namely: 3) The level of efficiency of the AC - AC UPS at the Airport Terminal is 95%, meaning
that the more power the source can provide by the Airport Terminal, this allows significant energy savings in
every work carried out at the airport, 5) The ability of the UPS to accommodate the transmitter system load,
which is for 34.16 minutes, this time is more than enough to switch the power source to the generator set, 6)
The UPS loads at the Airport Terminal by 60% (120 kVA is used from 200 kVA), more loads can still be
done, 7) UPS rating at the Airport Terminal has more power than the ideal UPS rating (oversizing UPS).
This is done to get a longer runtime, if there are additional tools, and not all electronic devices are backed
up by UPS.
