IMPROVING SUCKER ROD PUMP EFFICIENCY USING FREQUENCY CONTROLLED INDUCTION MOTOR

Relevance. In sucker rod pump installations, the cost of prime mover’s power use has substantial effect on overall operational cost. Reduction in consumption can lead to reduction operating Hence, as is dominant oil industry, any means which reduces energy produce considerable economic benefit and help meet efficiency targets standards. Due losses mover, surface transmission, string required lift always less than input mover. Induction motors, are widely used movers operate at significantly lower a load their rated capacity. Therefore, demand for improvement readily seen. This be achieved by controlling motor through AC-DC-AC converter. The main aim research develop control strategy that helps drive optimal efficiency. Objects: electrical drive, pump, producing well. Method: integrated simulation model consisting models converter, induction including iron loss, pump; vector control; generation magnetizing current trajectory one cycle operation. Result. unit operation flux based were compared using an model. results indicate about 1,6 % saved when operated calculated trajectory.
