Harmonic resonance damping on capacitor bank filters for industrial power system applications

Harmonic resonance is among important aspect need to be analyzed in a capacitor bank power system installation. For industrial power system with high operating power, the resonance control becomes a complex aspect. Therefore, effects of harmonics that are generated in the electrical system lines and capacitor banks are very evident causing amplification of the current at characteristics and non characteristics harmonics. This paper presents a solution for harmonic resonances mitigation in passive filters for reactive and harmonic power compensation system particularly in parallel connections. Then, an active power filter model with resonance damping is proposed and a topology model is established, the analysis results indicate that proposed has a good harmonic resonance damping characteristic. The proposed model is validated through simulations using Matlab-simulink^R.
