FIELD: relay protection, possible use for selecting stationary parts of a process occurring in an electric system.
SUBSTANCE: in accordance to the method, adjustment of adaptive filter for model signal is performed, which signal may change, and division of adjusted filter onto two transformers - direct one with positive scale multipliers and inverse one with negative ones, generation of two-dimensional signal in composition of output signal of direct transformer and inverted signal of reverse transformer, feeding of two-dimensional signal to executive relay with a characteristic set on a plane.
EFFECT: increased precision when determining homogeneity intervals.
