The paper presents an algorithm for optimizing the conditions of industrial thermal power plants in terms of repairs to their boiler units and turbine generators, which allows to determine the optimal composition of equipment removed for repair, taking into account the fuel used and the season. The algorithm is based on the dynamic programming method, which allows to set models of turbogenerators and boiler units in tabular form, which, when forming the equivalent characteristics of generators or boilers, allows simultaneous determination of the optimal condition of all equipment for a given electrical and / or thermal load of the power plant. The optimality criterion is the minimum of the total cost of the fresh steam needed to generate heat and power. The optimization algorithm and equipment models are specially adapted to the conditions of industrial power plants.
