Abstract


This paper first described the traditional cascade speed control system work principle and the analysis of the traditional cascade speed control system power factor low reason, and use the MATLAB/SIMULINK built traditional cascade speed control system simulation model, get the system power factor with the trigger Angle change curve; Secondly, this paper introduces the chopper type cascade speed control system, this paper puts forward the working principle of chopping type cascade speed control system power factor analysis and calculation of the basic method, and using MATLAB/SIMULINK built chopper type cascade speed control system simulation model for the calculation method of the calculation results are verified; Then analyzes the impact of chopper type cascade speed control system power factor factors, Finally, with parallel capacitor to chopper type cascade speed control system for reactive power compensation. The simulation results show that, the use of reactive power compensation method can effectively improve the chopper type cascade speed control the power factor of system.
