Steady state performance with unbalanced supply voltages may be treated by the method of symmetrical components. The three-wire supply voltages Va, Vb, Vc are decomposed into forward and backward components: Vaf = 13 (Va + aVb + a2Vc ); a = ej23π (7.115) Vab = 13 (Va + a2Vb + aVc ); Vbf = a2Vaf […]
