METHOD AND DEVICE FOR SYMMETRIZING THREE PHASE SYSTEM

PURPOSE: To quickly and easily symmetrize a generated 3-phase system by a multivariable adjustment system. CONSTITUTION: Positive-phase sequence and negative-phase sequence system components u1c 1, u1s 1, u2c 1 and u2s 1 are formed from measured voltages uR, uS and uT. These components generates pos...

Zusammenfassung:	PURPOSE: To quickly and easily symmetrize a generated 3-phase system by a multivariable adjustment system. CONSTITUTION: Positive-phase sequence and negative-phase sequence system components u1c 1, u1s 1, u2c 1 and u2s 1 are formed from measured voltages uR, uS and uT. These components generates positive-phase sequence and negative- phase sequence system operation values Ust , Ust1c , Ust2s and Ust2c respectively. The positive-phase sequence and negative-phase sequence system operational values Ust , Ust1c , Ust2s and Ust2c are converted into phase voltage operational values Ustr , Usts and Ustt and are supplied to angular symmetrical controllers 76, 78 and 80.
