Abstract

Consumption and transmission of electrical energy of low quality cause additional financial losses of market participants of electrical energy, the value of which can be many times greater than its cost. In the event of such a situation, the question of the allocation of financial compensation to the injured party among all the participants of this event is arising. Conducted studies have shown that an adequate solution to this problem is possible based on a distributed mathematical model of factual contributions determination factual contribution in voltage distortion at the point of common coupling. Since its application requires the construction of a measuring system distributed in space and synchronized to the time, which is a difficult task from a practical point of view, it is appropriate to reduce distributed mathematical model of factual contributions determination to the case of local measurements. The article presents the results of this reduction, which is based on the matrix method equivalenting schemes of electric circuits. The presented mathematical model which was obtained in such a way can be used to describe point of common coupling, where one side is connected to the consumer, and the other is an equivalent power supply system. During the equivalent transformations the structure of the equivalent circuit of equivalent power supply system is determined. The results of presented research can be used in the development of methods and means of factual contribution distribution of linear sources of distortion in voltage distortion at the point of common coupling according to local measurements figures.
