SERIES COMPENSATION IN ALTERNATING-CURRENT MACHINES Russian patent published in 2003 - IPC

FIELD: energy distribution and transmission devices. SUBSTANCE: in order to provide for series compensation in rotating ac machines connected directly or through static current converter to three- phase distribution or transmission line where stator winding of ac machine is connected in star, fundamental-frequency capacitive voltage circuit is inserted in each phase between low-voltage side of winding and ground point of distribution or transmission line. EFFECT: reduced system reactance, averted currents that might be induced by magnetic field of earth. 15 cl, 1 dwg
