The evaluation of damages caused by the existence of nonsymmetrical and deforming regimes

摘要

The damages are economic effects of some anomalous technical states. The technical literature doesn't contain mathematical models about provoked damages by electric energy non quality, summarizing only to determinate the effects and the quantification of energy effects. This paper tries to complete this hole by introducing mathematical models for provoked damages resulted by distortion and nonsymmetric regime. The study is structured in six parts. In the first part is made an evocation to economic evaluations, dedicated to supplying with electric energy of the systems, framing the approached topic in this subject. In parts 2 ÷4 it is presented the proposed mathematical model, regarding to evaluation of damages which are caused by the existence of deforming and non symmetrical regime in the electric networks. The following categories of damages are expressed: damages caused by the supplementary losses of electric energy; damages caused by the reduction of electric equipment's life time; damages caused by the unavailability of power and energy in deforming and no symmetrical regime. In the fifth part, are given the results of a study about the effect of the deforming and nonsymmetrical regime for a system; while in the last part are presented the conclusions of the study.
