A Study of Simulation Model of Doubly-fed Motor Based on Matlab/Simulink

摘要

This paper introduces the characteristics of doubly-fed motor. The mathematical model in the two-phase synchronous rotating coordinate system d-q of doubly-fed motor is given, and a simulation model is constructed by Matlab S-function based on the model. Simulation of doubly-fed motor on stator unity power factor vector control is carried out through the model and simulating waveforms are given. The simulation results illustrate that the doubly-fed motor simulation model by S-function has the characteristics of simple, fast and high precision. It provides a convenient pathway for the research of doubly-fed speed regulation system.
