В этой статье рассматривается асинхронный двигатель, который является основным потребителем электроэнергии, и его система мониторинга активного реактивного энергопотребления. Приведены сравнительный анализ, преимущества и недостатки преобразователя тока и датчиков асинхронного двигателя, используемых для управления и контроля различных потерь, возникающих в обмотке статора. Также впервые для контроля реактивного энергопотребления асинхронного двигателя был применён преобразователь тока, преобразующий трёхфазный ток в напряжение. Контроль и мониторинг потребления реактивной мощности асинхронного двигателя переменного тока объясняются с помощью аналитических выражений и графических моделей. В процессе мониторинга потребления реактивной мощности энергопотребления асинхронного двигателя изучались изменения электрических и магнитных процессов в обмотке статора асинхронного двигателя, их основные энергетические показатели, влияние коэффициента мощности cosφn , и коэффициента полезного действия ηn . В статье для контроля реактивной мощности асинхронного двигателя разработана форма быстрого преобразования Фурье (FFT) несинусоидальности в обмотке статора путём последовательного и параллельного подключения предлагаемого преобразователя тока в напряжение.

This paper discusses an induction motor, which is a major power consumer, and its active reactive power consumption monitoring system. A comparative analysis, advantages and disadvantages of current converter and induction motor sensors used to control and monitor various losses occurring in the stator winding are presented. Also, for the first time, a current converter converting three-phase current into voltage has been used to control the reactive power consumption of an induction motor. The control and monitoring of reactive power consumption of AC induction motor is explained with the help of analytical expressions and graphical models. In the process of monitoring the reactive power consumption of induction motor energy consumption, the changes of electrical and magnetic processes in the stator winding of induction motor and their main energy indices, the effect of power factor – cosφn , and efficiency ηn . were studied. In the paper, a Fast Fourier Transform (FFT) of non-sinusoidality in the stator winding by connecting the proposed currentto-voltage converter in series and parallel is developed to control the reactive power of induction motor.
