Retrofit Scheme of High-voltage Motors for Frequency Variability
This paper reports a retrofit carried out for realizing frequency variability function with respect to a high-pres-sure circulating pump of a thermal power plant and the proposed retrofit scheme according to the on-site actual situation and the customer's requirements.The scheme ensures the rotor's reliable operation and the unit safety by improving the protection configuration of the high-voltage frequency-variable motor.The scheme involves relatively small modifications and well satisfies the project's schedule requirements,which may provide a certain reference for subsequent retrofit pro-jects for frequency variability of factories'internal high-voltage motors.
