Предложен метод анализа дискретной кривой напряжения, который позволяет выявить и оценить экстремумы, и получить более полную информацию об изменениях напряжения в частности выделить участки кривой, напряжение на которых можно считать постоянным. Разработана методика его реализации, которая позволяет определить основные характеристики кривой напряжения, а также основные параметры колебания напряжения. Это исследование может быть использовано в дальнейшем для определения местоположения источника колебаний напряжения.
The purpose of work is development of a method of the analysis of a discrete curve of tension and development of a technique which allows to define the main of tension performance curve, and also key parameters of fluctuation of tension. The known methods of the analysis of the curves having local extrema can be used for assessment of fluctuations of tension, in particular, for definition of location of a source of fluctuation of tension. As showed results of a research the analysis of change of a curve of tension, except assessment of extremums and identification of sites of a curve of tension on which fluctuations are not observed allows to receive also other parameters characterizing fluctuations of tension, in particular: a range of change of tension number of fluctuations of tension for an observation time slice, a recurrence rate of changes of fluctuations of tension, an interval between changes of tension. The method is developed for the analysis of a discrete curve of tension which allows to reveal and estimate extrema and to obtain more complete information on changes of tension in particular to allocate sites of a curve on which tension can be considered constant. This research can be used further for definition of location of a source of fluctuations of tension.
