Study on the voltage stability of induction motor load

This paper conducts research on the voltage restoration characteristics of induction motor load in the context of large disturbances, and holds that, for a normally operating induction motor in the context of large disturbances, the voltage can maintain stable if the disturbances are removed in time. Additionally, this paper investigates the voltage collapse process of the induction motor in the context of small disturbances, maintaining that voltage collapse may occur when the induction motor voltage is below a certain value. Then, this paper analyzes the relations between induction motor instability and voltage instability. Finally, this paper reaches the conclusions of the mechanism of voltage stability and voltage collapse.
