Power Quality Improvement Using Active and Passive Power Filters
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2012, Vol 2, Issue 1
Abstract
Power quality standards (IEEE-519) compel to limit the total harmonic distortion within the acceptable range. Active power filter which has been used there monitors the load current constantly and continuously adapt to the changes in load harmonics. Hybrid active filter with proposed control algorithm for three phase hybrid power filter is studied here .It is composed of series active filter connected in series to the line and passive filter connected in parallel with the load . Traditionally, a passive LC power filter is used to eliminate source current harmonics when it is connected in parallel with the load and series active filter will compensate the voltages in the line. The proposed control algorithm is based on the generalized p–q theory. It can be applied to both harmonic voltage injection and harmonic current injection and also it improves the behavior of the passive filter. This control algorithm is also applied to shunt active power filter, combination of series active and shunt active and comparative study has been done. Simulations have been carried out on the MATLAB SIMULINK platform with different filters and results are presented.
