      JOHANNESBURG, 15 Kasım 2026 /PRNewswire/ -- Dağıtım ağı hizmetleri giderek daha karmaşık hale geldikçe, Cemig'in dağıtım cihazları veri aktarımında esas olarak kiralanan kamu ağlarına bağımlı hale geldi. Ancak bu model, önemli riskler barındırıyordu.

      CEMIG x Huawei

      • Kapsama eksiklikleri: Kapsama eksiklikleri: Brezilya'da operatörlerin şebeke kapsama alanı yalnızca yaklaşık %50 seviyesinde. Uzak ve ıssız bölgelerdeki çok sayıda dağıtım cihazı, uzun süreler boyunca iletişim kesintisi yaşanan bölgelerde kaldı. Arızalar meydana geldiğinde, personel onarım ve rutin kontroller için uzun mesafeler kat etmek zorunda kalıyor, bu da operasyonel verimliliği ciddi şekilde aksatıyordu.
      • Güvenilirlik eksikliği: Kamu şebekesi SLA'sı, elektrik şebekesi operasyonları için tasarlanmamıştır. Yağmurlu mevsimde, şiddetli hava koşulları sıklıkla baz istasyonlarında kesintilere veya mikrodalga bağlantı kesintilerine neden oldu ve dağıtım cihazlarının bağlantı oranı %90'dan yaklaşık %60'a düştü. İletişim kesintiye uğradığında, uzaktan kumanda komutları cihazlara ulaşamıyor veya cihazlarda yürütülemiyordu; bu da personelin manuel işlemler için sahalara gitmesini zorunlu kılıyordu. Bu durum, elektrik kesintilerinin giderilmesini ciddi şekilde geciktirdi, tedarik güvenilirliğini zayıflattı ve önemli ekonomik kayıplara neden oldu.

      Çözüm

      Bu zorlukların üstesinden gelmek için Cemig, çok sayıda teknik değerlendirme ve küresel kullanım senaryosu araştırması gerçekleştirdi ve nihayetinde Latin Amerika'daki enerji sektörü için ilk ticari 450 MHz özel kablosuz ağı birlikte kurmak üzere Huawei'yi stratejik ortağı olarak seçti.

      Başvuru Sonucu

      Saha testlerinin ardından müşteri, özel kablosuz ağın sağladığı faydaları bizzat deneyimleyerek dağıtım şebekesi modernizasyonuna olan güvenini artırdı ve gelecekteki enerji dönüşümü konusunda yüksek beklentiler oluşturdu: "Huawei, ihale sürecinde en iyi teklifi sunarak, yalnızca mevcut dağıtım şebekesi modernizasyon gereksinimlerimizi karşılamakla kalmayıp, gelecekteki yenilenebilir enerji entegrasyonu için de ölçeklenebilir bir çözüm önerdi. Huawei, enerji sektöründe kapsamlı bir deneyime sahiptir. Huawei'nin özel ağ çözümü sayesinde Cemig, yüksek kaliteli bir özel iletişim ağına sahip olacak. Cemig için bu ortaklık, teknolojinin çok ötesine geçiyor; gelecekteki iş büyümemiz için hayati önem taşıyor."

      1. Geliştirilmiş güç kaynağı güvenilirliği
      Özel kablosuz ağ, dağıtım terminali bağlantısını %99'a ve iletişim güvenilirliğini %99,99'a yükselterek Cemig'in güç dağıtım hizmet seviyelerini önemli ölçüde iyileştirdi.

      2. İş risklerinin azaltılması
      Özel kablosuz ağ, hat kayıplarını, SAIDI ve SAIFI değerlerini önemli ölçüde iyileştirebilir ve böylece Cemig'in düzenleyici kurumlardan ceza almasını önleyebilir.

      3. Garantili yatırım getirileri
      Özel kablosuz ağ, enerji hizmetlerini büyük ölçüde iyileştirerek Cemig'in ANEEL'in düzenleyici gerekliliklerini yerine getirmesini ve uygun yatırım getirisi elde etmesini sağlıyor.

      4. Genişletilmiş temel üretim uygulamaları
      Enerji üretim operasyonları için temel iletişim omurgası olarak özel kablosuz ağ, günümüzün dağıtım otomasyonu için güvenilir son mil bağlantısı sağlar. Ayrıca, büyük ölçekli akıllı sayaç entegrasyonu, hızlı dağıtık fotovoltaik (PV) sistemlerin benimsenmesi ve karmaşık mikro şebeke yönetimi gibi geleceğin temel uygulamalarını destekleyerek, geleneksel yük temelli elektrik üretiminden kaynak, şebeke, yük ve depolama arasında dinamik bir etkileşime geçişi teşvik etmektedir.
