Comparison of three evolutionary algorithms for harmonic mitigation using SAPF

2011 6th International Conference on Industrial and Information Systems, 2011
For power quality improvement, shunt active power filters (SAPF) having PWM controlled voltage source inverter (VSI) topology is extensively used in distribution networks, which utilizes the PI controller for reference voltage tracking. PI controller tuning with the assumption of linear PWM model leads to unsatisfactory results under varying operating ...

Adaptive Harmonic Current Compensation Method with SAPF based on SOGI

2018 IEEE International Power Electronics and Application Conference and Exposition (PEAC), 2018
The shunt active power filter (SAPF) cannot compensate harmonic and reactive current completely when capacity is limited. Aiming at the problem, an adaptive harmonic compensation control method based on second order generalized integrator (SOGI) is proposed with calculating APF’s capacity strictly.

Sparse LMS control algorithm for Fuel Cell based SAPF

2016 IEEE Uttar Pradesh Section International Conference on Electrical, Computer and Electronics Engineering (UPCON), 2016
Nowadays, modification and hybridization of the Custom Power Device (CPD) topology are occurring massively to provide the better power quality service in the distribution system. The selection of a suitable adaptive control algorithm for such CPD is also a tough job for the researchers due to the complexity of the power system.

An Improved DC-Link Voltage Control Strategy of SAPF under Unbalanced Loads

Proceedings of the 2020 3rd International Conference on Electronics and Electrical Engineering Technology, 2020
The shunt active power filter (SAPF) based on three-leg voltage source converter is widely used to compensate the harmonic currents caused by nonlinear loads of grid. However, when the nonlinear loads are unbalanced, the grid currents compensated by SAPF are still unbalanced and distorted even an accurate current detection method is adopted. The reason

Harmonic mitigation and resonance damping of MMC-SAPF with low switching frequency

2021 IEEE 4th International Electrical and Energy Conference (CIEEC), 2021
The shunt power capacitor will cause parallel resonance in the medium voltage (MV) power distribution system with nonlinear load. MMC-SAPF with low switching frequency is applied to handle this problem. Firstly, topology and control of device including modulation strategy is studied.

Performance analysis of SRF based SAPF with PI and FUZZY controllers

2015 International Conference on Control Communication & Computing India (ICCC), 2015
Current harmonics are the major problem that seen in the distributed system due to the wide spread usage of the harmonic loads. Conventionally, the harmonic related problems are reduced by using the passive harmonic filters. The performance of the passive filter largely depends up on the system impedance and it subjected to change frequently.

A current control method for quick-response and disturbances-rejection on SAPF

Proceedings of the 33rd Chinese Control Conference, 2014
Shunt active power filter with LCL output filter involves the tracking of transient current with high frequency harmonic components. The current control brings some complexity. This paper presents a kind of current control algorithm, which combines the triangle carrier comparison method with hysteresis control method.

The space vector control of the SAPF in the condition of non-ideal source

2010 International Conference on Mechanic Automation and Control Engineering, 2010
As a result of three-phase voltage of non-ideal power distortion and asymmetric, containing a large number of negative sequence components, traditional i p -i q method which detect harmonic currents will have error, so the positive sequence voltage component of A phase need be extracted.
