Estudo de um combinador linear de fourier aplicado à rede elétrica monofásica

Abstract

The search for computer and electronic resources to improve electrical network efficiency and power quality is increasing. In order to perform and adequate power processing is necessary to detect in real time the voltage and current signals from the power grid. This paper proposes an adaptation of the algorithm Fourier Linear Combiner and WeightedFrequency Fourier Linear Combiner, established in biomedical engineering applications to work in power systems applications. In order to obtain experimental data, the algorithm was implemented in electromagnetic transient software PSCAD/EMTDC in comparison with other detection algorithms voltage signals. The implemented tests addressed the detection of the fundamental and harmonic components. Further, the algorithm was subsequently loaded into a Digital Signal Processing (DSP), in order to obtain experimental data.
