Abstract :
This paper reviews the application of an adaptive var compensator to reduce voltage flicker associated with the stalling of large motors. The ease considered involves the sequential starting of two 1000 hp motors in an across-the-line mode. The motors are served by a 44 kV-4.16 kV dedicated substation. The 44 kV transmission line also serves over 2000 residential and commercial customers through two widely separated 44 kV-12.5 kV substations. Several methods of reducing flicker were considered. Customer complaints associated with voltage excursions during motor starting were successfully resolved
