FIELD: electricity.
SUBSTANCE: dynamic process is represented in the form of an ensemble of harmonics, every of which is a time row reflecting in a symbolic form the dynamics of the appropriate frequency component, stationarity of the process is identified from the moment, when in a continuous selection of values of the first harmonics 5% of these values are outside the range from zero to maximum value of this harmonic, and 95% of these values are inside this interval, for the stationary process by a combination of symbolic characteristics of all harmonics its type is calculated within a scenario of multiple increase of the period.
EFFECT: higher extent of algorithmisation of a process of identification of emergency modes of width-pulse converters of energy, aimed at practical application for higher reliability and safety of their functioning.
