Laboratory implementation of a hybrid series active power filter system part II: Series active filter designing

Abstract

Practical and simulation studies of a hybrid system of series active power filter and shunt passive filter is presented in this two-part paper. Whereas part 1 concerns dimensioning, designing and starting up of the shunt passive filter, this second part is dedicated to dimensioning, conceiving and implementing of the series active filter. The works consist mainly to realize a two-level full bridge voltage inverter based on IGBT's. The respective overvoltage circuit and average control circuit are also conceived. The control is conducted in an open loop, the reference signals are identified using the p-q theory concept, and for launching the gating signals, the carrier-based PWM method is employed. The implementation of the whole system gave satisfactory results and improved the quality of power in the main utility side.Index Terms-dimensioning and designing of the active filter, carrier based PWM open control loop, shunt passive filters, series active power filter, p-q theory algorithm.

Enhancement of Power Quality in Domestic Loads Using Harmonic Filters

“…Various literatures have proposed PQ-theory for singlephase systems, some of the implementations can be seen in literature [21], [25]. Based on [21], the following equations were used to realise it.…”

“…This methodology is explained by the researchers in [23]- [24]. The single-phase version of this technique can be seen in [25]. For this study, the three-phase version of this was adapted for single phase application.…”

Controller Implementation and Performance Evaluation of a High Power Three-Phase Active Power Filter using Controller Hardware-in-the-Loop Simulation

“…2.4 gives an idea of the structure of a hybrid APF. Scholars introduce design and implementation of series hybrid APF in these papers [36][37][38][39][40][41]. The series hybrid APF is capable of compensating current as well as voltage harmonics [36].…”
