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: The paper deals with the control methods of the active power filter with voltage
source which can be used for reduction of high harmonics in the supply current. For the correct
function of the filter, it is necessary to determine magnitude of the currents, which have to be
added to load current so as to eliminate high harmonics in the supply current. Several methods
of the filter current control are described 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: A control algorithm for a three-phase hybrid power filter is proposed. It is constituted by a series active filter and a passive
filter connected in parallel with the load. The control strategy is based on the vectorial theory dual formulation of instantaneous
reactive power, so that the voltage waveform injected by the active
filter is able to compensate the reactive power and the load current
harmonics and to balance asymmetrical loads. The proposed algorithm also improves the behavior of the passive filter. Simulationshave been carried out on the MATLAB-Simulink platformwith different loads and with variation in the source impedance.This analysis allowed an experimental prototype to be developed.
Experimental and simulation results are presented. Platform: |
