A literature review on reduction of harmonics using active power filter

The disturbances or harmonics in power system lines can be minimised by Active Power Filters (APF). An advancement of APF technologies and proper application of active power filter is to use good method for current or voltage reference generation are reviewed in this paper. Here we discussed about the critique of harmonics disturbance issues and their effects on quality of power. The basic configuration of APF is combination of series and shunt (hybrid) APF, series APF and shunt APF are explained. This understanding explains the implementation of p-q extinctions to produce reference signals. Apart from this, APF photovoltaic system is also analysed.
