【Abstract】 According to the characteristics of pumping station,AC-excited motor model was constructed. The system adopted a stator flux-oriented vector control strategy and double-PWM converter to regulate motor’s speed,active and reactive power. The simulation platform based on Simulink of Matlab was set up. Experiment waves and their analysis were given. The results verify that pumping sta-tions can exert their potential when AC-excited motors have been applied,and the purpose of high efficiency,energy conservation can be achieved.更多还原
