The paper proposes a solution for improving the power quality in a transportation system. The experimental determinations revealed a high level of harmonics and a high consumption of reactive power. The simulation using MATLAB/Simulink software was conceived and validated. A solution using passive filters is proposed and analyzed.
The aim of this paper is to perform an analysis of the shunt Active Power Filter (APF) operating with unbalanced loads. The impact of the load imbalance on the APF performance is mathematically demonstrated and validated with experimental results using a 25 kVA shunt APF prototype. The APF operation in such conditions is affected by the appearance of DC-link voltage ripple at twice the grid frequency...
Low power factor and increased current harmonic content are some of the negative effects of static power converters usage. To correct these disadvantages, active power filters with complex current control schemes can be used. This paper proposes an new method for tuning the resonant controllers also known as proportional sinusoidal-signal-integrator (P-SSI) controllers, based on Naslin polynomials...
