有源电力滤波器谐波补偿技术研究

Research on harmonic compensation technology of shunt activepower filterAbstractIn today's society,power electronic devices are widely used,bringing peopleconvenience,but also bring harmonic problems.Harmonic wave makes the problem of powerquality more and more serious,and the electric equipment is very sensitive to power quality,people's demand for power supply quality is also more and more high.Because active powerfilter has good function of suppressing and compensating harmonics,and becomes aneffective tool to control harmonics,the following is to study active power filter by studyingharmonic compensation technology.First introduced in this paper briefly expounds the appearance and harm of harmonic,and then analyzes the present situation of domestic and foreign research on active filter andthe significance of research,also introduce the working principle of active filter,function,advantages and disadvantages,topology structure and the design methods used in theintroduction,testing method and the control method for harmonic compensation effect playsan important role,finally through the matlab simulation model and the waveform analysis,this topic research.Key words:harmonic compensation;Active power filter;Detection;Control.
