METHOD FOR ADVANCED CHANGE OF GENERATOR EXCITATION VOLTAGE WITH ASYNCRONOUS MOTOR CONNECTED

摘要

A method for advanced change of generator excitation voltage with an asynchronous motor connected which includes possibility to change of period (frequency) of rotation of the primary motor and shaping generator output voltage which is applied to an asynchronous motor in the moment of connection. To the moment of generator output voltage connection to asynchronous motor a period (frequency) thereof rotation is changed to increase generator output voltage for a magnitude equal to a half of predict undershoot; thereafter, output voltage is applied to an asynchronous motor and using electronic sensor revolutions of the asynchronous motor is measured to the moment until quantity of revolutions does not exceed a half of the rated value; thereafter using an arithmetic device and demultiplexer voltage of generator excitation is reduced to the rated value.
