METHOD OF ALLOCATION OF FREE COMPOSITION IN THE CONTROL OF ZERO SEQUENCE OF THE ELECTRICAL NETWORK AND DEVICE OF AUTOMATIC ADJUSTMENT OF THE IRRIGATED REACTOR ON ITS BASIS Russian patent published in 2017 - IPC H02J3/18 

FIELD: electricity.

SUBSTANCE: invention can be used as a part of devices for automatic adjustment of static and plunger arc suppression reactors (ASR) in electrical networks with isolated and compensated neutral, as well as in networks with combined grounding mode and in devices for operation in networks with a reduced Q-factor and parallel connection of several ASR. In the method of isolating the free component in the circuit of residual electrical network and the device automatically configure the quenching reactor at its base for driving the damped oscillation in the loop of zero-sequence (LZS) apply a series of pulses of alternating polarity, digitize input analog values of the perturbation signals using the calculated value of the sampling frequency Fd, separation of the free component produces a special algorithm in adder-accumulator is determining the value of detuning and its output values for the limits specified setpoints affect the change in the inductive or capacitive ASR current.

EFFECT: improved accuracy of tuning and reliability of measurement results in the entire range of control of arc suppression reactors.
