Control of the initial conditions in the control of electromagnetic transient modes of asynchronous electric drives

Abstract

Three methods of controlling the initial electromagnetic conditions of the transient modes of an asynchronous electric drive are considered. The first is based on determining the required time from known drive parameters. The second is a direct change in comparing the angular paths of the rotor and the voltage vector of the network. In the third method, three-phase systems of network voltage and emf are used. motor induced in the stator windings by damped marnite rotor flow. The structural diagrams of the corresponding devices and recommendations for various applications are given.
