Modeling and simulation based on double closed loop vector controlof 300MVA motor generator

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.
