METHOD FOR AUTOMATIC ADJUSTMENT OF VOLTAGE AT ELECTRIC SUBSTATION Russian patent published in 2014 - IPC H02J3/12 

FIELD: electricity.

SUBSTANCE: method includes setting the ratio between voltage at near and further consumers receiving power from outgoing lines of the electric substation at which voltage is being controlled and voltage of the secondary transformer winding of the electric substation, measuring the actual voltage at the near and further consumes, measuring the actual voltage of the secondary transformer winding, comparing said voltages with standard values, if the actual voltage at the consumer differs from standard values, determining the actual deviation of the ratio between the given and actual voltages at control points, using the obtained voltage deviation as said correcting signal.

EFFECT: maintaining normal voltage and increasing accuracy of voltage adjustment.
