As a compromise between economy and good performance, this paper adopts the combined system using active power filter (APF) and static var compensator (SVC) to compensate reactive power and harmonic currents simultaneously. The SVC is constructed by fixed capacitor (FC) and thyristor controlled reactor (TCR), and the APF is constructed by a voltage source converter and its filter reactor. SVC acts...
A new high capacity comprehensive compensation system based on APF (active power filter) and capacitors is proposed to meet the requirements of harmonic elimination and reactive power compensation in low-voltage distribution power system, where APF is used to cancel the harmonic current and the capacitors are used to compensate the fundamental reactive power. Then the mathematical model of APF is...
This paper presents a shunt active power filter application mainly for source current harmonic elimination. The proposed control method is based on instantaneous reactive power theory. A three-phase voltage source inverter bridge with a dc bus capacitor is used as an APF. It requires measuring the source currents with reduced number of current sensors than the existing methods. The source currents...
This paper presents the required harmonic power and rating issues of the active filter and power components. A design procedure is presented to select the DC bus capacitor that covers all modes of operation. The effect of the DC bus ripple on the compensation capacity is analyzed. A typical problem is included to illustrate the design approach followed by simulation results showing the static performance...
In order to compensate more reactive power and lower the power level of the active power filter (APF), a hybrid filter system based on a combination of an APF and a thyristor switched capacitor (TSC) is presented. This system combines the good dynamic compensation performance of the APF and higher power level of the TSC. It can eliminate harmonics and compensate the power factor effectively in power...
