Abstract: The entire operating parameters of the 300MVA motor generator were equivalently calculated 
using the existing test data and nameplate data and its equivalent model was established by analyzing its 
mechanical structures and electrical characteristics. Based on Simulink, the vector control model of high power 
induction motor with double closed loop was established and simulated, the quality of current and torque 
waveform can be improved by adjusting the Proportional-Integral parameters of speed ring and current ring. The 
simulation results show that the system has good dynamic and static performance and can meet the requirements 
of starting and running of the motor generator.

Key words: Motor generator, Vector control, Proportional-integral, Speed ring, Current ring
