Self-oscillations in the electric drive TPN-AD when the valves are synchronized with the mains voltage.
Abstract
A method for analyzing the self-oscillation mode in an electric drive is considered a thyristor voltage converter-asynchronous motor. The transfer function of the motor is represented as a transfer function of several typical links reflecting the shape of the transient response of a motor operating at a constant speed. Conclusions are made about the stability of an open-loop system.
