This paper proposes a novel method to estimate the influence of domestic consumers on power quality, namely harmonic pollution, using fuzzy logic. Comparing the conventional measurement approach, the proposed fuzzy logic method is simpler and time saving. The fuzzy logic system used to quantify the impact on harmonic distortion, contains several modules: the fuzzifier, database, base rule and defuzzifier...
The paper presents a method based on the Fast Fourier Transform and Gauss Window combined with a recursive algorithm for the estimation of the voltages and currents harmonics and interharmonics. The proposed method uses pairs of band-pass filters to obtain the frequency domain components of the power signals. The band-pass filters emerge from the grouping made between the Gauss Window and the Fourier...
