Automatic device and method for compensating reactive component losses in ac networks

An automatic device for compensating losses in a consumer network on reactive component of the voltage supplied from an AC network, comprising for each phase of a three-phase AC network:

• a step-up transformer for increasing the supplied voltage to 10-100 kilovolts, comprising a magnetic core having three limbs and three primary windings disposed on each limb, respectively, for connecting to respective phase of the AC network, and three output secondary windings;
• a step-down transformer for reducing the voltage output by said step-up transformer to the value equal to the voltage supplied to the consumer, said step-down transformer comprising a magnetic core having three limbs, and three primary windings disposed on each limb, respectively, identical to the three secondary windings of said step-up transformer and connected opposite to said secondary windings of the step-up transformer, and three secondary windings identical to said primary windings of the step-up transformer,
• wherein the opposite connected secondary windings of the step-up transformer and respective primary windings of the step-down transformer form three second voltage harmonic generation circuits, which, when voltage is supplied to the step-up transformer from the AC network, generate a second voltage harmonic in windings and cores of said transformers so that frequency of external voltage oscillations of the AC network is doubled in said second harmonic voltage generation circuits and autoparametric resonance is generated therein, and electromagnetic field strength oscillations occur on the small hysteresis loop of the down-transformer core;
• wherein, when an inductive load of the consumer network is connected to the secondary windings of the step-down transformer, current in the secondary windings and the load increases and cosy factor decreases due to restoration of the angle between electric field strength vector E and magnetic field strength vector H to 90 degrees, which, given the autoparametric resonance, provides the transfer of oscillation energy to the main hysteresis loop of the magnetic core of the step-down transformer, thereby compensating losses on reactive voltage component in the consumer network.
