An active power filter (APF)based on digital signal processor (DSP) and complicated programming logic component (CPLD) is designed in this paper. Solft and hard wares are introduced and the simulation experiment to compensate the reactive power and harmonics in three-phase four-wires system is done. By using Matlab. simulation model is build for the device. The result shows that this model can …
This paper presents three harmonic simulation test systems. The purpose is to demonstrate guidelines for the preparation and analysis of harmonic problems through case studies and simulation examples. The systems can also be used as benchmark systems for the development of new harmonic simulation methods and for the evaluation of existing harmonic analysis software.
