2092084 9303430 PCTABS00019 A faster, more controllable phase-shifting transformer system (20, 120) is provided, along with a method of retrofitting and upgrading a preexisting system for faster operation, and a method of applying a desired phase shift to the voltage on a polyphase transmission line (22, 122). A phase-shifting transformer set has series and regulating transformers (30, 40) coupled together by a switching network (50). An optional modulator (60, 80, 90) modulates the phase shift voltage about a nominal level established by the switching network (50). A thyristor augmented switching network (250, 350, 450) may have a pair of thyristor valves (206, 208; 406, 408) augmenting a reversing switch (204; 404) or a thyristor (311) augmented load tap changer (310) for varying the phase shift discreet step magnitude. For continuous effective phase shift control, a thyristor valve (416, 416', 416'') and a harmonic filter (418, 418', 418'') are in parallel with each excited winding (446, 447, 448), and a harmonic filter (414) is in parallel with each regulating winding (444).
