Abstract :
The paper presents results of reliability forecasting for domestic, technologically congener power units rated at 370 MW operating in Belchatow Power Plant and Opole Power Plant as lignite fired and hard coal fired respectively. Estimation of parameters for identified empirical probability distribution functions of operation time and repair time was done by the method of a histogram with a set number of observations in each class. The study includes expected values of reliability indices calculated for main generating installations of both unit types.
