Abstract


This paper originates from the chopper type cascade speed control system of the actual production application, according to the basic principle of the system, using MATLAB Simulink software package and PSB (power system module library build simulation test model, in view of the system, the harmonic detailed theoretical analysis and experimental research. To determine the main harmonic link, and through the test measured waveform combining theory to harmonic condition and characteristics are analyzed. The theoretical analysis on source basic principle of the filter and the effects of its filtering performance of related factors. Based on the system design of passive filter device, realized based on reactive power compensation capacity method and minimum capacitance installed capacity method of engineering method parameter design and simulation test, and from the filtering performance and reactive power compensation two aspects carries on the analysis comparison of results.
