Study and Application of Two New Excitation Control Schemes for Synchronous Motor

Concerning the existing deficiencies of the synchronous motor under the constant excitation, two control schemes for improving the stability of operation of synchronous motor are proposed in this paper. The simulation researches of the control schemes with the practical data of a synchronous motor are made. The simulation results show that the proposed schemes are stable and feasible. These schemes have been put in practical use and its running effect are satisfactory.
