Abstract :
The load leveling of an induction motor with pump load using a power angle regulator is described. The power flow is controlled by changing the power angle of the voltage vector. The power angle is controlled using a phase shifter so as to reduce the power pulsations which are produced by pump load. The novel power angle regulator which is called the solid state phase shifter (SSPS) employs an AC switch with PWM schemes for continuous and rapid control. The power pulsations have been reduced from 63% to 10% of their average level.<>
