FIELD: electrical engineering.SUBSTANCE: electric energy consumption determination method includes the following sequence of actions: the signal being measured, that corresponds to the consumer AC and AC voltage, is subjected to integrated Fourier analysis, sampling frequency adjustment to the oscillating grid frequency of the energy distribution grid for which purpose one determines the corresponding principal oscillation vectorimmediately from two consecutive periods of the signal measured, determines the phase angle (??) confined between the both vectors which angle is applied during sampling frequency adjustment.EFFECT: ensuring high accuracy of consumed electric energy determination at measurements sampling frequency adjusted to oscillating grid frequency.2 cl, 2 dwg |
