FIELD: electrical engineering.
SUBSTANCE: field of application: electrical engineering. According to the method, the free component of the transient process is used to determine the network zero-sequence network parameters, bearing full information about the natural frequency and quality factor of the circuit, which is extracted from the bias voltage of the neutral using discrete wavelet analysis, and to generate a reference current pulse in the network circuit, the source is used in the large duty cycle mode, having a small installed power. When the natural frequency of the circuit deviates from the industrial frequency, a regulating effect on the change in the inductance of the reactor is formed.
EFFECT: technical result is an increase in the accuracy of tuning to any given compensation mode for any high-frequency noise and distortion.
