Оптимальне керування реактивним навантаженням в умовах несиметрії напруг електричних мереж

Abstract

The Thesis is devoted to the scientific task decision of optimal reactive load control in voltage unbalance conditions of electric grid. Research activities analysis for detection of effectiveness increase possibility at the expense of control modes by reactive load is developed. The magnitudes increase of voltage unbalance factors and voltage fluctuation when battery of static condensers were turned on for reactive load control is shown. The mathematical models which allow to obtain solution vector for reactive power control by static condensers battery which is joined by star with zero scheme and is connected to node with asymmetric voltage and numerical method of its analysis are developed. The model of control system by reactive load which realize mathematical models and computing method of analysis are developed.
