Abstract
Today, the increase in reactive power consumption far exceeds the increase in active power consumption. Due to the increasing demands of the end-users for the quality of the supply of electricity, the problem of joint selection of rational sections and places of installation of reactive power compensation in the distribution line becomes relevant. A mathematical model and algorithm allowing such a choice are proposed. The mathematical model can be used both in the design of new lines and in the reconstruction of existing lines. An example is given.
Highlights
The problem of reactive power compensation in electrical networks is multifaceted and includes a number of subtasks, such as the choice of compensation devices, the choice of cross-sections of wires and cables, the improvement of the electrical quality indicators, the optimization of the load of transformers, Reduction of electricity costs and many others [1]
Numerous scientific studies have been devoted to these sub-tasks, both by the Electricity Network Organization and by consumers for different purposes
The most important influence on the reactive power balance is the installation of compensating devices near the loads, i.e. in the consumer networks, but the positive effect of such an installation extends to the network organization
Summary
The problem of reactive power compensation in electrical networks is multifaceted and includes a number of subtasks, such as the choice of compensation devices, the choice of cross-sections of wires and cables, the improvement of the electrical quality indicators, the optimization of the load of transformers, Reduction of electricity costs and many others [1]. The work of [2] focuses on the problem of disconnect in the actions of electric network organizations and consumers in the installation of compensating devices. The authors [2] of propose a model and methodology for obtaining information on the possible reduction of network losses due to the installation of compensating devices on the side of consumers. The present work explores ways of optimizing the crosssection of the wire and determining the locations of the compensating devices for new and reconstructed distribution lines. For this purpose, mathematical models of lines under different optimization conditions are presented
