Under normal operating conditions thermo-flow properties of steam turbines vary. This process of deteriorating indicators - except failures - is continuous. That is why a study of the possibility of building continuous diagnosis system has been undertaken. Changes mentioned above are very slow, so it seems advisable to build a steam turbine simulator program. It enables precise study of the influence of particular and complex factors on turbine characteristics changes. Assumptions and general simulator programs structures are presented. With the aid of this tool we investigated the impact of typical damages which may occur in a turbine: gland degeneration and blade salinity. Concept diagnosis based on the change of characteristics is presented. This diagnosis concept was verified and tested using data from simulating program and large data files from power plants archives (DCS).
