FIELD: power industry.
SUBSTANCE: there proposed is method for determining service life of component of power plant with the following stages: determination of the first performance value for service life of power plant component at constant capacity; determination of the second performance value for service life of power plant component at varying capacity; determination of the first statement of equivalence, by means of which the pre-set operating mode of power plant component at constant capacity is represented depending on the number of the first performance values; determination of the second statement of equivalence, by means of which the pre-set operating mode of power plant component is represented depending on the number of the second performance values; determination of the number of the first and the second performance values obtained during actual operating mode of power plant component; determination of sum of the number of the first and the second performance values; taking the decision on service life on the basis of the determined sum.
EFFECT: improving accuracy for determination of service life of power plant component.
