DEVICE FOR COMPENSATION OF CAPACITIVE CURRENTS OF SHORT CIRCUIT IN NETWORKS WITH ISOLATED NEUTRAL 6-10 KB Russian patent published in 2017 - IPC H02H9/08 H02M7/44 

FIELD: electricity.

SUBSTANCE: device contains a three-phase disconnector, a meter, a control system, a three-phase static converter of electrical energy, a current sensor, a voltage sensor. The phases of the static converter of electrical energy are connected to the network through a current sensor connected to a three-phase disconnector connected to the phases of the network and a control system that is connected to a meter, current sensor, voltage sensor, three-phase static converter of electrical energy, and contains Hilbert converter, block for calculating the direct, reverse and zero sequence of current and voltageαβ, blocks of transition from the coordinate system ABC to the coordinate αβ system, blocks for transition from the coordinate system to the stationary coordinate system dq, subtraction schemes, setting blocks, proportional-integral regulators, Coordinate systems dq to coordinate systemαβ, blocks of transition from the stationary coordinate system dq to the coordinate system ABC, summation circuits, reference voltage generator, comparators, logical devices NOT, blocks of angle calculationγ, the comparison unit, connected accordingly.

EFFECT: increasing the speed and providing control over the direct and reverse sequence of current.
