ABSTRACT:
An induction generator system is disclosed for utilization with an oil producing well having casing gas available at the wellhead and an existing electrical power system. An electric motor is coupled to the existing electrical power system and is utilized as a generator to drive a submersible pump or other electrical load. A gas engine which is powered by the casing gas is mechanically coupled to the electric motor by means of a drive belt and is utilized to drive the electric motor at a speed greater than the synchronous speed of the motor. While the electric motor is driven at a speed greater than its synchronous speed it will generate electrical energy which can be utilized to carry the electrical load. A novel control system is utilized to control the operation of the engine/motor generator system in response to variations in motor speeds, engine operating parameters and load/voltage conditions.
