THERMAL ANALYSIS OF XLPE INSULATED SUBMARINE CABLES FOR DIFFERENT LOADING CONDITIONS
Öz: Submarine cables are critical assets that play an indispensable role in interconnected power systems, particularly in cross-sea energy transmission and offshore wind turbines. Their importance is further accentuated in exigent situations such as natural disasters and war, which emphasize the need for secure, reliable and uninterrupted energy supply. Furthermore, the investment and operating costs of submarine cables are relatively higher than other power system equipment, making it essential to operate them under the rated operating conditions to prevent possible faults and ensure power system stability. As thermal stress can lead to damage of cable insulation, it is an essential parameter to consider. Overloading increases thermal stress, resulting in rapid aging of the cable insulation and a shorter cable lifetime. Therefore, it is imperative to determine the maximum conductor temperatures and current carrying capacities of submarine cables under varying loading rates and ambient conditions using thermal analysis. In this study, thermal analyses are carried out for a three-phase, 220 kV HVAC, XLPE insulated submarine cable under different loading conditions. The findings demonstrate that the maximum temperature, current carrying capacity, and total losses of the cable are significantly impacted by loading rate, phase imbalance, and seawater temperature.

Öz: Denizaltı kabloları, enterkonnekte güç sistemlerinin en önemli ve kıymetli varlıklarından biri olup hem deniz aşırı enerji iletiminde hem de açık deniz rüzgar türbinlerinde yaygın biçimde kullanılmaktadır. Bu kablolar, özellikle doğal afet ve savaş gibi kritik ve stratejik durumlarda daha da önem kazanmaktadır. Ayrıca denizaltı kablolarının hem yatırım ve hem de işletme maliyetleri diğer güç sistem ekipmanlarına kıyasla ciddi derecede yüksektir. Bu sebeplerden ötürü, kablonun nominal işletme şartları içerisinde çalıştırılması ve böylelikle olası arızaların engellenmesi güç sistem kararlılığının sağlanması bakımından elzemdir. Kablo izolasyonun zarar görmemesi için dikkat edilmesi gereken en önemli parametreler arasında ısıl zorlanma gelmektedir. Aşırı yüklenmeye bağlı artan ısıl zorlanmayla kablo yalıtkanı daha hızlı yaşlanmakta ve kablonun işletme ömrü azalmaktadır. Bu nedenle, denizaltı kablolarının farklı yüklenme oranları ve ortam şartları için maksimum iletken sıcaklıklarının ve akım taşıma kapasitelerinin ısıl analizler yardımıyla belirlenmesi önem arz etmektedir. Bu çalışmada, üç faz, 220 kV HVAC, XLPE izoleli bir denizaltı kablosunun farklı yüklenme koşulları altında ısıl analizleri gerçekleştirilmiştir. Sonuçlar, yüklenme oranının, faz dengesizliğinin ve deniz suyu sıcaklığının kablonun maksimum sıcaklığı, akım taşıma kapasitesi ve toplam kayıpları üzerinde önemli etkisi olduğunu göstermektedir.
