AB - Representation of probabilistic technique for evaluation of thermal power  system reliability is the main subject of this paper. The system of thermal  power plant under study consists of three subsystems and the reliability  assessment is based on a sixteen-year failure database. By applying the  mathematical theory of reliability to exploitation research data and using  complex two-parameter Weibull distribution, the theoretical reliability  functions of specified system have been determined. Obtained probabilistic  laws of failure occurrence have confirmed a hypothesis that the distribution  of the observed random variable fully describes behaviour of such a system in  terms of reliability. Shown results make possible to acquire a better  knowledge of current state of the system, as well as a more accurate  estimation of its behavior during future exploitation. Final benefit is  opportunity for potential improvement of complex system maintenance policies  aimed at the reduction of unexpected failure occurrences.
