METHOD FOR EXCITATION VOLTAGE PREVENTION CORRECTION OF GENERATOR RUNNING FOR ASYNCHRONOUS MOTOR

摘要

A method for excitation voltage prevention correction of a generator running for an asynchronous motor comprises a primary motor capable of changing a primary motor rotation period (frequency) and shaping generator output voltage supplied to the asynchronous motor when initiation. To a moment of supplying generator output voltage to the asynchronous motor the rotation period is changed to increase output voltage for a half of predictable dip. Changed generator output voltage is supplied to the asynchronous motor, at the same time generator output voltage is decreased to the rated voltage. Generator excitation voltage is corrected using an arithmetic unit and demultiplexor functional structure.
