The increasing share of renewables in electricity production adversly affects the operation of thermal plants, including steam turbine units. Intermittency of renewable sources results in high variability of steam turbine operating conditions, which together with the inherent scatter of turbine operating parameters significantly complicates their lifetime assessment. The paper presents a concept of lifetime monitoring system in scope of creep-fatigue damage. The system is based on online and offline calculations, performs online analysis of measurement data and takes into account the results of material tests. Functionality of the system main modules is described and mathematical models suitable for online calculations are presented. A general concept of hardware configuration for the system is proposed as well.

Wzrastający udział odnawialnych źródeł energii w produkcji prądu ma niekorzystny wpływ na pracę elektrowni cieplnych, w tym bloków parowych. Niestabilność źródeł odnawialnych skutkuje dużą zmiennością warunków pracy turbin parowych, co w połączeniu z nieodłącznym rozrzutem parametrów pracy turbin w znaczący sposób komplikuje ocenę ich żywotności. W artykule przedstawiono koncepcję systemu monitorowania żywotności w zakresie zużycia zmęczeniowo-pełzaniowego. System ten oparty jest na obliczeniach w trybie online i offline, wykonuje na bieżąco analizę danych pomiarowych oraz uwzględnia wyniki badań materiałowych. Omówione zostały funkcje głównych modułów systemu wraz z propozycją modeli matematycznych odpowiednich do obliczeń w trybie online. Zaproponowano również ogólną koncepcję konfiguracji sprzętowej systemu.
