Description: Abstract—In this paper a current reference generation
method for a voltage source shunt active power filter is
examined. The proposed method improves the harmonic
filtering by compensating the delays in the system. In
stationary operating point of the load the method uses
measurement data sampled in previous periods to generate a
reference prediction. Since in transient state of the load the
prediction no longer holds true, a computational control delay
compensation algorithm is used in the reference generation
instead of the prediction in this situation. Changing the
algorithm according to the operating point guarantees effective
harmonic compensation in all operating points. In this paper
the system performance is examined with an active filter
simulation model. Platform: |

Description: This paper, focus on the study and design of a shunt active power (APF) filter for the compensation of harmonic currents and reactive power in polluted environment and under unbalanced network voltage. In APF design and control, p-q theory was often served as the basis for the calculation of compensation current. In this theory, the mains voltage was assumed to be an ideal source in the calculation process. However, in most of time and most of industry power systems, mains voltage may be unbalanced and/or distorted. For these reasons, we used a new technique with instantaneous power theory (p-q theory) based on Phase Locked Loop (PLL) in order to control APF under unbalanced mains voltage. A pulse width modulation (PWM) technique is used to generate the switching signals to the shunt APF.-This paper, focus on the study and design of a shunt active power (APF) filter for the compensation of harmonic currents and reactive power in polluted environment and under unbalanced network voltage.

Description: This paper proposes an effective control scheme
for three-phase three-wire (3P3W) active power filter using
neural-based harmonic identification scheme. To achieve
excellent steady state and dynamic response, the feedback
control plus feed-forward control structures is utilized in the
proposed control algorithms. The steady-state error minimization
is achieved by the feedback loop, where the proportional
integral regulators were adopted in d-axis and
q-axis of the synchronous rotating reference frame synchronized
with grid voltages by using the phase-locked loop. The
adaptive linear combiners are utilized in the feed-forward
loop, which serves the purpose of load disturbance rejection,
and it significantly enhances dynamic performance of active
power filter (APF). Platform: |

Description: In this paper, an efficient active power filter (APF) scheme is developed to estimate and compensate for harmonic distortion in an electrical power network. The developed APF control scheme is based on a double proportional feedback controller and a single-phase voltage-source half-wave bridge inverter. The proposed filter uses a Multi-layer Artificial Neural Network (MLANN) with a shift method for estimating system harmonic currents and voltages at a dedicated point. The proposed scheme is tested on a 13 bus industrial distribution system. The obtained results ensure the effectiveness of the proposed filter. The system is simulated in MATLAB-Simulink and simulation results prove that the polluting harmonics have been greatly reduced. Platform: |
