KT SAT Builds 'Satellite Trunked Radio System'

Ensuring Reliable National Power Grid Operation and Wide-Area Blackout Prevention During Disasters
Applying Satellite Communication to Emergency Power Call System for 24-Hour Stable Grid Operation Guarantee

[Asia Economy Reporter Eunmo Koo] KT SAT announced on the 2nd that it has established the Korea Power Exchange's 'Satellite Power Dispatch Telephone System' using the Mugunghwa satellite. This system is designed to ensure stable power supply by managing communication between the Power Exchange and power generation and substation facilities during disaster situations.

The Korea Power Exchange issues 'power dispatch instructions' to power plant and substation operators to start or stop generators for managing the national power supply. Timely 'power dispatch instructions' are especially critical during emergencies such as disasters or terrorist attacks that disrupt infrastructure.

However, if wired communication networks such as telephone and text messages are cut off due to disasters, it becomes difficult for the Power Exchange to issue 'power dispatch instructions' to operators. This ultimately increases the risk of blackouts as the appropriate amount of power cannot be supplied where needed.

The Satellite Power Dispatch Telephone System supports power supply management by enabling communication between facilities using satellites instead of wired networks. Satellite communication is unaffected by ground disasters, making it suitable as an emergency communication network when wired communication is unavailable.

Song Kyung-min, CEO of KT SAT, said, “In an era where disaster-prepared communication networks for government agencies and public infrastructure are essential, we are pleased that satellite communication can play a valuable role,” adding, “As Korea’s leading satellite operator, we will continue to actively contribute to public safety and the stability of citizens’ lives through high-quality satellite communication networks.”
