Power Co., Inc. (Davao Light) continues to future-proof its distribution
network by building smarter and digital power substations.
On December 8, 2021, the company energized its first fully digital substationlocated in the downtown area of Davao City.
The P.Reyes Substation uses software-defined networks (SDN) which is a type ofcommunication network that is more secure against cyber threats than thetraditional ethernet networks. This system was developed in-house usingcommercially-available technologies. Both Davao Light and its fellow AboitizPowersubsidiary, Visayan Electric Company, Inc. pioneered the use of SDN in thecountry.
DavaoLight Assistant Vice President for Engineering Engr. Enriczar Tia said that thedigitalization of substations boosts their efficiency and reliability. “The substationis now easier to monitor and faster to troubleshoot when problems are found.This helps reduce the frequency and duration of power interruptions and thus,is advantageous during this time when people are almost always at home for workand school.
Buildinga fully-digital substation focuses on converting analog values to digitalvalues so they can be easily shared between devices in a substation. With this,there are unlimited ways to configure a substation to improve its performance,reliability, and monitoring.
“Thedifference between a conventional and a digital substation is like using a CRTTV where you can watch limited channels only, and now having a smart TV whereyou have unlimited choices of shows to watch,” Tia added.
Aside from the digitalization of P. Reyes Substation, Davao Light also upgraded itscapacity to 50MVA which will ensure an adequate supply of reliable power to aconsiderable number of customers in the downtown area of Davao City, especiallysince fast developments are experienced around the area.
Davao Light looks forward to digitalizing other existing substations and building newdigital and smarter facilities to provide stable and reliable power to thecustomers it serves.
