Pattern classification of waveforms using LVQ1

This paper describes an application of the artificial neural network (ANN) technique using the learning vector quantization 1 (LVQ1) method, as a preprocessing for analyzing power system load characteristics. The clearer load characteristics are, the more accurate the power system analysis is. However, it is an important problem that it takes a long period of time to determine whether the measured data in power system are suitable for the analysis or not. Therefore the authors have developed a pattern classification technique for solving this problem using the LVQ1 method. Brand-new equipment using this technique has been manufactured and is in test at a substation of the Chubu Electric Power Co., Inc, Japan.
