A fuzzy logic application for identification of harmonics disturbances sources
This paper represented an application of fuzzy logic to power quality issue. It describes the sources of harmonics detected, by using fuzzy sets and IF-THEN inferences rules. Harmonics can create unwanted impacts on power systems and to end-users. Electrical utilities, manufactures and customers have been bothered by harmonic distortion problems in power system. The harmonics is based on power quality and according to the IEEE 519-1992. The harmonic signals and spectrum are determined by the application of a fast Fourier transform (FFT). A fuzzy inference system is experimentally implemented for these cases, showing the general procedures of how to use this theory. It appears that fuzzy set theory can play an important rule in diagnosing power quality disturbances, and hence it can offer insights towards the satisfaction of the needs of manufacturers, utilities and customers.
