Abstract

The purpose of research was to improve electric power quality due to non linear load in industry using passive fi lter, series active fi lter, and three phase hybrid active fi lter. There were two operation modes, namely circuit connected to balanced and unbalanced non-linear load. The fi lter circuit was modeled mathematically using current control techniques with pulse width modulation (PWM) and Dual of Instantaneous Reactive Power Theory. Power quality parameters were source current dan voltage THD, current dan voltage unbalanced, and input power factor of sytem based on IEEE-519 Standard, ANSI/IEEE 241-1990 and PLN Standards. The research shows that the system on four compensations connected to unbalance non linear load, produces average THD current smaller than the system connected balanced non-linear. The use of series active fi lter and hybrid active filter was able to decrease source current THD in accordance with 519-1992 IEEE Standard. At the same conditions, if the circuit has been connected unbalance non linear load, then unbalanced source current is greater than the system connected balanced non linear load. The circuit connected unbalanced non linear load was able to generate input power factor is slightly higher than balanced non-linear load. The value of source voltage THD of system connected balanced and unbalanced non-linear load for all conditions was relatively small, below 1% level, and have already met voltage harmonic limit within of IEEE 519-1992 Standard. The value of unbalanced source voltage without and with fi lters on both modes were relatively stable. The systems connected two modes of non linear load only was able to increase source current harmonics and unbalanced current, but has no signifi cant impact on changes of voltage harmonics and unbalanced voltage.
