Abstract

This paper presents three-phase shunt active power line conditioners (APLC) for harmonics and reactive power compensation due to non-linear loads in the distribution network. The compensation process proposed is a sinusoidal extraction control method, which consists of positive-sequence voltage detector for regulating the supply voltage and instantaneous reactive power (p-q) theory for fundamental extraction from the distorted line current. The shunt active filter voltage source inverter’s switching pulses are generated through an adaptive-hysteresis current controller (HCC). The adaptive-hysteresis bandwidth can be adjusted based on compensation current variation that is used to optimize the required switching frequency. This will improve the active power filter performance. The shunt-APLC system is validated through extensive simulation under steady and transient states with non-linear load conditions.
