초록

A power control system for a turbogenerator which provides electrical power to one or more pump-jack oil wells. When the induction motor of a pump-jack oil well is powered by three-phase utility power, the speed of the pump-jack shaft varies only slightly over the pumping cycle but the utility power requirements can vary by four times the average pumping power. This power variation makes it impractical to power a pump-jack oil well with a stand-alone turbogenerator controlled by a conventional power control system. This power control system comprises a t...

1. A system, comprising:a turbogenerator; a cyclic motion machine driven by an electric motor; a low frequency inverter powered by said turbogenerator, said inverter connected to said electric motor; and a controller controlling said turbogenerator and said inverter to establish a variable frequency time profile for each cycle of said cyclic motion machine and to vary the frequency of said inverter according to said variable frequency time profile to provide a generally constant power level to said electric motor.
