Предложен новый метод измерения активной мощности и действующего (средне квадратического) значения переменных сигналов в течение интервала времени, вдвое меньшего по сравнению с другими известными методами. Измерение выполняется простым суммированием выборок мгновенной мощности без подстройки времени измерения в соответствии с частотой сигнала. Математическое моделирование позволяет оценить точность предлагаемого алгоритма.

A new method of measurement of active power and effective value of AC signals over a time interval twice shorter than in other known methods is suggested. The measurement is carried out by simple summation of instantaneous power sampling without measuring time and signal frequency adjustment. The computer simulation allows to estimate the accuracy of proposed algorithm.
