Enhancing the method to determine power losses when specifying the location of the power source.

Abstract

Introduction. Currently much attention is paid to energy efficiency and economy of the electric power complex. The laws of the Russian Federation emphasize the importance of reducing the number of redundant electric power systems. Optimization is carried out in terms of capital and operating costs. Research on the development of new techniques is ongoing. The problem of determining the dependence of the consumer load on the operating parameters of the system still relevant while calculating operating costs. In the Khanty-Mansiysk Autonomous Okrug, a large part of electric energy consumption is accounted for oil and gas producing companies. The main consumers are installations of electric centrifugal pumps. In most cases, they are equipped with synchronous electric motors. In this regard, the creation of modern design assistance methods is required. The methods should include consideration of the dependence of the load on the operating parameters when calculating operating costs. Goal. The study aims to enhance methods of the calculation power loses for optimal power source placement. Materials and methods. The study is based on mathematical modeling, multi-criteria optimization, and artificial intelligence systems were used in the work. Results and discussion. The concept of an automatic power source location detection system was formed. The concept included modified methodic of determine of the power loses. The power loss values when using a load in the form of a static characteristic are 5…17 % higher than with a constant load value. The deviation of the   power loss value calculated in the RastrWin3 complex and the presented mathematical model was no more than 5 %. This can be considered insignificant. Conclusion: The dependence of the consumer load on the operating parameters of the system should be taken into account while determining   the location of the power source.
