Shunt Active Power Filter

2013
Shunt active power filters have been introduced as a way to overcome the power quality problems caused by nonlinear and reactive loads [9, 14, 23]. These power electronics devices are designed with the goal of obtaining a power factor close to 1 and achieving current harmonics and reactive power compensation [5, 6, 15]. The usual approaches [5, 15] for

Improved shunt active power filters

2008 International School on Nonsinusoidal Currents and Compensation, 2008
This paper describes a shunt active power filters (APF) with improved dynamic performance. When the value of load current changes rapidly, the APF transient response is too slow, the line current suffers from dynamic distortion. This distortion causes an increase of harmonic content in the line current, which is dependent on a time constant.

Shunt active power filter with ADMC330

Proceedings IPEMC 2000. Third International Power Electronics and Motion Control Conference (IEEE Cat. No.00EX435), 2002
In this paper, we describe a scheme for the shunt active power filter with ADMC330 (single chip DSP microcontroller) which was developed successfully. The results of experiment indicate that harmonic currents in three-phase three-wire system could be compensated successfully.

Compensation Characteristics of Shunt Active and Series Active Power Filters.

IEEJ Transactions on Industry Applications, 1993
AbstractActive power filters have been used in practice to suppress the harmonic interference in power systems. To compensate for harmonic currents of loads, active power filters usually are connected to power systems in parallel with the loads.

A notch filter based active damping of llcl filter in shunt active power filter

2017 International Symposium on Power Electronics (Ee), 2017
Shunt 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

Real-Time Shunt Active Power Filter Compensation

IEEE Transactions on Power Delivery, 2008
This letter presents the application of a real-time simulation technique to shunt active power filter compensation of the harmonic currents and reactive power in the power system. Available literature details several techniques developed and implemented to perform real-time simulations on the power system analysis.

Energy controlled shunt active power filters

COMPEL - The international journal for computation and mathematics in electrical and electronic engineering, 2007
PurposeShunt active power filters are used to decrease or almost eliminate non‐active currents flowing through the supply source. Numerous control methods of active filters have been proposed in many papers. The aim of this paper is to demonstrate a simple but very effective method of obtaining the compensated load active current.Design/methodology ...

Shunt Active Power Filter and Its Application

2010 International Conference on Challenges in Environmental Science and Computer Engineering, 2010
With the extensive application of high-power switching devices, the quality of electric power is growing problem seriously, which causes the current (voltage) distortion, producing a large number of harmonics. This paper introduces the principle, structure, device development and the characteristics of active filter, and its application in power system

Power Quality Improvement using Shunt Active Filter

2017 International Conference on Current Trends in Computer, Electrical, Electronics and Communication (CTCEEC), 2017
In this paper Active filters are used to improve the quality of the power in the load side of the power system. This consists of two parts,1)Simulation in which we are adopting the method of hysteresis control method to reduce the third harmonic at the load side.2)Using a model of MOSFET and gate drivers to minimize the third harmonics at the load side.
