METHOD OF AUTOMATIC ADJUSTMENT OF CURRENTS OF MULTI-PHASE SYSTEM AS TO SPECIFIED PHASE AT COMBINED POWER TAKEOFF Russian patent published in 2010 - IPC H02J3/01 

Abstract RU 2390900 C1

FIELD: electricity.

SUBSTANCE: method consists in generation by means of additional power source to each of the rest (n-1) phases of currents, which are pre-formed so that in each adjustable (n-1) phase of the main n-phase network the geometrical sum of currents - generated to adjustable phase and with current of its load can be equal as to current modulus to the current equal to current in reference phase, and the angle formed with the current of the latter and with total current of adjustable phase following the reference one at forward sequence of phases, as well as between total currents of neighbouring (n-1) adjustable phases can be equal to electrical degrees. At that, power takeoff to the above additional power source used for formation of asymmetry compensation currents is performed from combination of at least two minimum loaded phases which are pre-determined by the condition of decreasing asymmetry in adjustable n-phase system.

EFFECT: increasing quick operation, economy, simplifying the implementation and enlarging application range.
