Unbalanced Nonlinear Loads Harmonic Compensation Using Fuzzy Based Control of Series Active Filters

M. Hosseini Firouz, B. Alefy, H. Memarinezhad

Abstract :

The indiscriminate use of non-linear loads has given rise to investigation into new compensation equipment based on power electronics. The aim of this equipment is the elimination of harmonics in the system and reduction in reactive power flow. Depending on application type, series or parallel configurations or combination of active and passive filters are used. Active power filters can be used in conjunction with passive filters improving compensation characteristics of the passive filter and to avoid the possible occurrence of the generation of series or parallel resonance. This paper presents a fuzzy logic controlled series active power filter used to compensate for harmonic distortion due to unbalanced non liner loads in three-phase four-wire systems
