An analysis of operation conditions of last stages of 30MW class CHP turbines is presented. The analysis is based on real data taken from DCS of a large domestic CHP. A program aimed at improving the performance of those end stages was proposed and subsequently implemented in practice.
Podano przykład ilustrujący możliwości analizy krzywej wybiegu turbiny parowej na podstawie wyników rejestracji cyfrowej z wykorzystaniem układu DCS. W tym celu przedstawiono porównanie wyników rejestracji przebiegu czasowego zmian prędkości obrotowej wirnika turbiny parowej dla kilku przypadków odstawienia, które wykorzystane zostało do poszukiwania przyczyn jej awarii.
