The application of DSP in shunt active power filter

2011 Second International Conference on Mechanic Automation and Control Engineering, 2011
DSP chips are widely used in automatic control, mage processing, communications technology and other fields. In this paper, the application of DSP in shunt active power filter (SAPF) was discussed. Taken a DSP as the core controller, the experimental study on the SAPF was carried out, and the results of experiment were analyzed.

Control Techniques for Shunt Active Power Filters

2020
Reliability and quality are two most important facets of power delivery system. Wide use of nonlinear and electronically switched devices in distribution systems hinders the quality of supply. The problems of power quality include voltage fluctuations, flicker, harmonics, and asymmetries of voltages.

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 ...

Seven-level shunt active power filter

2004 11th International Conference on Harmonics and Quality of Power (IEEE Cat. No.04EX951), 2005
In this work, the seven-level cascaded type inverter is used as a shunt active power filter to exploit multilevel inverter advantages. The capacitor voltage control technique used as a harmonic current extraction method for the two-level inverter is extended to the seven-level shunt active power filter.

The Simulation and Analysis of the Shunt Active Power Filter

2010 International Conference on Electrical and Control Engineering, 2010
Base on the characteristics of the shunt active power filter, we uses the power electronic devices of the MATLAB/Simulink to model the system, uses self-compiled S-function to carry out the ip-iq current detection algorithm. In order to compensate the harmonic currents generated by the non-linear load and the reactive power of the process, the PWM ...

A shunt active power filter: development of properties

COMPEL - The international journal for computation and mathematics in electrical and electronic engineering, 2004
Numerous types of shunt active power filters have been proposed in many papers. The classification of these filters depends on various points of view. However, every type of a shunt active filter, which compensates non-active component of load current, irrespective of the method used to detect this component and control strategies of the filter, should

A novel active damping method for LCL-filter-based shunt Active Power Filter

2012 IEEE International Symposium on Industrial Electronics, 2012
Three-phase shunt Active Power Filters (APFs) are connected to the grid through inductance or LCL filter. Comparing to single L filter, LCL filter is more effective, e.g. better switching harmonics suppression and lower output impedance, but such solution causes stability problems. In order to assure stable operation either a damping resistor or active

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

Research on series-shunt compound control applying to shunt active power filter

2013 10th IEEE International Conference on Control and Automation (ICCA), 2013
The basic principle of shunt active power filter(SAPF) is that the output compensation current is equal to the harmonic current with reverse direction, the performances of SAPF contain dynamic response and static precision. Aiming at the defect of PI control applying to SAPF has low static precision, compound control method based on putting repetitive ...
