Method for detecting in real time of disturbance voltage signals in the transmission and distribution networks of electric power

摘要

Method for detecu00e7u00e0o, in real time, disturbance signals to teijsao in network transmission and distribution of electrical energy, comprises a uni method for the detection of disturbance voltage signals in the transmission and distribution networks of electric power is constituted of The following parties: (a) techniques of signal processing, based on the bandstop filter of 2 order.Implemented in the field of operator lie, applied for the extraction of transient component (1),Which is defined as the subtraction of the fundamental component of the voltage signal; (b) processing techniques of signals applied to the extraction of parameters based on higher order statistics of the transitory component; (2) the) grading techniques based on linear and network Neural MLP to, from the vector of parameters based on higher order statistics.To generate a numerical value to be analyzed for the purpose of detecu00e7u00e0o (3); (d) technique heaveside to inform from the outlet of the linear classifiers, applied when the window signal has length equal to 128 and 256, and those based on neural network MLP, designed for use when windows of S. Inais whose lengths are equal to the 32 and 64.If occurred or not in the window of the disturbance voltage signal portion (4) and, finally, use the procedure for detection of disturbances in the voltage signal to detect the second initial and final occurrence of the disorder (5).
