| Abstract: | Introduces threc-level frequency control of motor speed system of medium voltage and high power synchronous motor, which is equipped with the new switching device IGCT. The composition of the inverter control circuit parts and the role of the various sectors are analyzed too. Adopting the graphical simulation method facing the control system structure, a simulation of the inverter circuit is implemented, giving the speed simulation curve, the output line voltage harmonic analysis and the output line current harmonic analysis. Simulation results show that the system has excellent speed-regulating performance and lower harmonic content. |
