АНАЛІЗ ЕНЕРГЕТИЧНИХ ПРОЦЕСІВ В ТРИФАЗНОМУ СИЛОВОМУ АКТИВНОМУ ФІЛЬТРІ З ВИКОРИСТАННЯМ СПЕКТРАЛЬНОГО МОДЕЛЮВАННЯ

Abstract

The problem of electricity quality to consumers with non-linear, variable load caused the development of technical solutions as a managed device controlled filtering compensates active power filter is discussed. In known scientific papers the issues of energy redistribution in the power circuit filter elements are clarified. The purpose of this paper is to give analysis of energy processes in a three-phase active power filter using spectral modeling with the presence of poly harmonics mode settings. Based on existing models of active rectifiers the spectral model of the active power filter is developed. For certain conditions for static mode the temporal and spectral dependence of power and energy in the circuit elements is obtained. Analysis of the results revealed that the contours of the device circulating components of high-power compared with the basic harmonic, that circulates between the network and the device, and the fundamental harmonic is absent in the spectrum of the power capacitor. Operation device provides the energy redistribution between phases of the network due to its partial reswitching of reactive elements.

В роботі проведено аналіз енергетичних процесів в трифазному силовому активному фільтрі з використанням його спектральної моделі. На підставі існуючих моделей активних випрямлячів розроблена спектральна модель активного фільтра, в результаті отримані графіки потужності та енергії в системі для статичного режиму роботи пристрою за визначених умов. Аналіз отриманих графіків та спектрів відповідних параметрів режиму фільтру дозволив оцінити розподіл електричної енергії в елементах фільтру
