Direct power control of shunt active filter
2007 European Conference on Power Electronics and Applications, 2007This paper presents a new control method entitled direct power control (DPC) for shunt active power filtering, which is applied to eliminate line current harmonics and compensate reactive power. Its main goal is to rebuild active and reactive powers to be compared to references values using hysteresis control.

A review of active filters for power quality improvement
IEEE Transactions on Industrial Electronics, 1999Active filtering of electric power has now become a mature technology for harmonic and reactive power compensation in two-wire (single phase), three-wire (three phase without neutral), and four-wire (three phase with neutral) AC power networks with nonlinear loads. This paper presents a comprehensive review of active filter (AF) configurations, control

Design and control of LCL-filter with active damping for Active Power Filter
2010 IEEE International Symposium on Industrial Electronics, 2010In the application of shunt Active Power Filter (APF) to compensate nonlinear load's harmonic, reactive and negative sequence current, it is more effective to use a LCL-filter than an L-filter as an interface between the Voltage Source Converter (VSC) and grid. In this paper, a designing procedure of LCL-filter for APF is introduced, which is aimed for

An Universal Active Power Filter Controller System
2009 IEEE Industry Applications Society Annual Meeting, 2009An universal active power filter controller system is proposed that adapts itself to both harmonic current source type loads as well as harmonic voltage source type loads is presented in this paper. The system level harmonic filtering application issues of a multiple and clustered harmonic producing load site, such as at an industrial load site or at a

An active power filter and unbalanced current compensator
IEEE Transactions on Industrial Electronics, 1997This paper presents the synthesis and performance of a shunt active power filter based on the three-phase pulsewidth modulation (PWM) voltage converter connected to the AC mains. Current harmonics and asymmetries caused by nonlinear loads can be compensated.

A notch filter based active damping of llcl filter in shunt active power filter
2017 International Symposium on Power Electronics (Ee), 2017Shunt Active Power Filter (APF) is a custom power device applied in electric grid system in order to compensate harmonic currents generated by nonlinear loads. Shunt APF operates by firing power electronic devices of voltage source inverter (VSI) to produce the compensation currents. The VSI also generates high frequency switching ripple harmonics that

Backstepping control for active power filter with LCL filter
2nd IET Renewable Power Generation Conference (RPG 2013), 2013Active power filters are widely applied in power system to deal with distorted currents caused by nonlinear loads. As the active power filter (APF) with LCL filter is a serious nonlinear system, conventional control methods cannot have satisfactory performances. A nonlinear control method, backstepping control for active power filter with LCL filter is

Synchronized active power filter
IEEE Compatibility in Power Electronics, 2005., 2005The aim of the paper is to demonstrate how to use a shunt active power filter to maintain invariable power of a supplying voltage source, even though the supplied load varies randomly. The Section 4.3 is specially related to this feature. The S. Fryze's definition of load current components is used as a basis for the construction of a family of active ...

Performance evaluation of LLCL filter for active power filter
2016 IEEE 16th International Conference on Environment and Electrical Engineering (EEEIC), 2016Active Power Filter (APF) is an inverter based device that compensates the harmonic currents generated by nonlinear loads. Inverters release high frequency switching ripple harmonics. In early studies, APFs have been generally interfaced to the grid via a single L filter to reduce these harmonics.

Adaptive Compensation of Reactive Power with Shunt Active Power Filters
Conference Record of the 2006 IEEE Industry Applications Conference Forty-First IAS Annual Meeting, 2006This paper describes an adaptive method for compensating the reactive power with an active power filter (APF), which is initially rated for mitigation of only the harmonic currents given by a nonlinear industrial load. It is proven that, if the harmonic currents do not load the APF at the rated power, the available power can be used to provide a part ...
