STATISTICAL ANALYSIS OF REACTIVE ENERGY LOSSES IN DISTRIBUTION ELECTRICAL NETWORKS
PURPOSE. Based on the statistical analysis the paper demonstrates the expediency of reactive energy losses minimization in operating conditions in order to improve the efficiency of distribution electrical networks. METHODS. The study involves the methods of mathematical statistics. The analysis algorithm of the scheme-mode situation of an electrical network is proposed. It is aimed at the identification of problem places in a network. A procedure of the structural analysis of reactive energy losses in an electrical network is offered as well. RESULTS AND THEIR DISCUSSION. The influence of reactive energy losses on the efficiency and reliability of electrical network operation is shown. The analysis of the scheme-mode situation and the structural analysis of reactive energy losses are performed on example of 110-35 kV distribution electrical network of the city of Vladivostok. The centers of increased losses of reactive energy are identified. The effect of reactive energy losses minimization for electrical networks is considered. CONCLUSIONS. Being of complex character the effect of reactive energy losses optimization has a positive influence on such significant characteristics of electrical network operation as reliability of power supply, stability, quality of electrical energy and profit.
