| Abstract: | In view of the deficiency of the speed governing system controlled by slip frequency,a new control strategy is proposed and its working principles are explained.The modeling and simulation of the improved slip frequency control system is completed by using the electrical principles and Simulink and Power System toolbox in the Matlab software.The modeling of the speed governing system is expounded and the simulation model and results of improved slip frequency AC speed control system are presented.The simulation results of open-loop control system and those of improved closed-loop control system by slip frequency are compared,which shows the correctness and superiority of the proposed method. |
