Reactive power compensation for sustainable development of power grids in cities of Uzbekistan

This article explores the critical role of electrode technology and energy efficiency in the process of electric arc welding for the purpose of melting and shaping steel. It delves into the challenges posed by electrodes that directly impact the technology’s effectiveness and energy consumption. Furthermore, the article conducts an analysis of various electrode types and classifications utilized in steel melting processes, emphasizing their efficient utilization in the steel production industry. As the demand for steel production continues to rise, so do the requirements for electrode strength and durability. However, modern metallurgical processes often encounter the recurring issue of electrode degradation and failure. Through comprehensive research, this article sheds light on the common problems associated with electrode failure during steel melting operations.

The problem of using electrodes in the steel melting process

Rakhmonov,

Korjobova,

Kholikhmatov

et al. 2023

“…The hopes that the decline in industrial production, the general "fading" of business activity and the resulting reduction in energy consumption in the 90s would protect the country from the energy crisis, and the fuel and energy complex from acute problems, did not come true, as a number of other factors (some of them continue to manifest themselves to this day) [2][3][4][5][6][7][8][9]:…”

Stimulating environmental protection activities in the energy sector

Mamarasulova,

Bobojonov,

Djurayev

et al. 2023

The article discusses issues of stimulating environmental protection activities in the energy sector. In addition, the factors influencing the decline in industrial production volumes are considered: the close interdependence of economic and energy factors in shaping the state of security of territories; a decrease in the level of energy efficiency during a period of general stagnation; the increasing influence of economic indicators of the operation of energy systems on the degree of security threats, such as chronic underinvestment in fuel and energy sectors, non-payments, etc.; excessive load on the fuel and energy complex as the “locomotive of the economy”; high level of monopolism in the fuel and energy sector; uneven territorial distribution of fuel and energy resources and productive forces, both of natural origin and due to the dominance of an administrative-centralized management system for many decades; distortions in prices and tariffs for energy resources, etc.

Device for reducing asymmetry

Usmanov,

Kholikhmatov,

Rikhsitillaev

et al. 2023

This article focuses on the development and analysis of a device designed to reduce voltage asymmetry in electrical systems. Voltage asymmetry can lead to negative consequences, such as equipment overloads, increased energy losses, and unstable power supply. The article discusses the fundamental principles of the device, its components, and control methods to achieve an optimal level of voltage symmetry. The presented research results emphasize the device’s effectiveness in improving the quality of power supply and ensuring the stable operation of electrical grids.
