Analytical Method for Determining Optimal Parameters and Schemes for Voltage-Regulated Induction Motors With Single-Phase Power Supply

Abstract

On the basis of the method of symmetric components, an analytical method is proposed for calculating the coefficients that determine the relationship between the components of the positive and negative sequences of the parameters of the operating mode of an induction motor and the parameters of its power supply for some circuits for the inclusion of voltage-controlled three-phase induction motors with phase-shifting capacitors powered by a single-phase network. On the basis of this technique, the optimal parameters of phase-shifting capacitors can be determined and rational schemes for connecting three-phase induction motors to a single-phase network can be selected.
