Reliability Modelling of Combined Heat and Power Generating Power Plant Units

This study briefly sets out a 3 and more state reliability description of combined heat and power generating units (of extraction condensing and back-pressure steam turbine power plant units). The new procedure improves the accuracy of system-level reliability (Loss of Load Probability (LOLP)) calculations for power generation systems by giving a more differentiated (and thus more accurate) description of the available capacity from extraction condensing and back-pressure turbine power plants. Applying the 3 or more state reliability model for power plant units with extraction condensing and back pressure turbine and the deduction of the reliability calculation s input data form the novelty of the newly developed calculation method.
