摘要：A method for controlling power supply to an induction motor is disclosed. Abaseline reactive power on an induction motor during operation is initially measured. Anew reactive power for offsetting the baseline reactive power is determined. Appropriate
capacitance is then applied on the power lines for the induction motor in order to supplythe new reactive power to the induction motor. After the appropriate capacitance hasbeen added to the induction motor, an instant reactive power on the induction motor ismeasured. A determination is made whether or not the instant reactive power on theinduction motor is equal to or less than the new reactive power. If the instant reactivepower is equal to or less than the new reactive power, the instant reactive power on theinduction motor is continuously measured. If the instant reactive power is greater thanthe new reactive power, the added capacitance is removed from the power lines, and anew baseline reactive power is obtained.
