Analysis of irregular electricity consumption

Abstract

The paper analyzes the current electricity consumption modes. The problem of irregular electric power consumption has been noted. The advantages and disadvantages of systems of measuring electricity consumption of sinusoidal systems have been given and their inaccuracy under variable loading and non-sinusoidal operation modes has been proven. The influence of irregular energy consumption has been analyzed. It has been confirmed that the traditional power coefficient takes no account of uneven consumption. Power losses have been assessed, that appear in electrical network when its transfer to consumers, using the least possible value of power losses. The formula has been developed for calculating the power coefficient, which takes into account all inactive components of total power and describes any electricity consumption mode, while the cosφ - only in a particular case of symmetric sinusoidal load currents. The average value of power factor per time interval has been determined, which takes into account negative effects of irregular consumption, and depends only on a consumer. This coefficient also includes irregular consumption schedule. The corresponding conclusions were made.
