Abstract

The paper presents selected examples of ALSTOM Power experience in the scope of modernisations of large output turbine generator sets at power plants in poland. Depending on turbine age and its wear degree and the other Unit devices as well as depending on financial resources and forecasted operation period of devices, the various scenarios of modernisation can be chosen. Turboset modernisation / retrofit effects are strongly depending on the depth and scope of reconstruction of main unit devices. Widely understood modernisation is one of the Polish power industry chances. The possibilities of turbine modernisation being able to be chosen and those already carried out by now together with their checking out by adequate measurements have been presented in this paper.
