Special issue “ELECTRIC POWER. Transmission and Distribution” for the 24th World Energy Congress (UAE, Abu Dhabi), September 2019

Interview with Andrey Cherezov, Deputy Minister of Energy of the Russian Federation

In an exclusive interview, Deputy Minister of Energy of the Russian Federation Andrey CHEREZOV and editorial director of “ELECTRIC POWER. Transmission and distribution” journal Ekaterina Guseva discuss the implementation and improvement of risk-based management of facilities and resources in the Russian energy companies, broach the questions of improving the reliability of energy systems and districts characterized by high-risk of power supply interruptions, and examine successful implementation of projects aimed at improving reliability. Much attention is paid to preparation for the autumn-winter period and improvement of the methodology for assessing the entities readiness for the autumn-winter period.

Interview with Andrey Mayorov, Deputy General Director – Chief Engineer of Rosseti

“Digital Transformation 2030” concept was approved within the framework of Rosseti Board of Directors official meeting chaired by the Minister of Energy of the Russian Federation Alexander Novak on December 21, 2018. The concept implies a complete transformation of power grid infrastructure through the introduction of digital technologies by 2030. The key issues of concept implementation are the topic of conversation with Andrey MAYOROV, Deputy General Director – Chief Engineer of Rosseti.

Interview with Alexander Yatsuk, General Director of Special Design Engineering Bureau in Electrochemistry with experimental factory (SKTBE)

…the transition to new alternative energy sources is a dire necessity. Scientists may be mistaken for 50 or even 100 years, but fossil fuels will be exhausted someday. Loss of energy sources is the same “end of the world”, as any other global catastrophes and troubles. That country, the scientists and specialists of which will be the first ones to find the optimal solution to the problem of switching to inexhaustible energy sources, will gain a dominant position in the world. This is especially important for Russia…

The paper considers decisions on developing an effective and reliable power grid in the Arctic region of the Russian Federation using the solutions of Rosseti Tyumen. These solutions are needed for creating up-to-date Arctic electrical network using the positive results of research and development implementation and taking into account existing climatic conditions.

The current transformation of power system towards a decentralized model brings some features in the changing power supply from the practice of complex distribution networks. The presence of prosumers in the grid and the need to integrate renewable energy sources require a dynamic change in the transmission and distribution of electricity. The key features of new generation networks are power lines operation with alternating feed from different directions and smart control of power system facilities, which require not ordinary maintenance, but a quick response to the state of power equipment.

PJSC “Rosseti” maintains 44 thousand km of new conductor types or 1% of the total conductors’ length (4.5 million km). Self-supporting insulated wires of various modifications (more than 41 thousand km or 0.9% of the total conductors’ length) and bare conductors (less than 3 thousand km or less than 0.1% of the total conductors’ length) are among these conductors. In addition, Russian modern power grid is characterized by physical deterioration and obsolescence of equipment. As a result, low energy efficiency of power facilities takes place. The most important indicator of power system efficiency is the level of energy losses. With the growing power losses in electrical networks, the number of urgent problems increases. Reconstruction and technical re-equipment of electrical networks, application of advanced technical developments in design solutions, implementation of modern technologies and materials increasing reliability, durability and maintainability of power transmission lines are among these problems.

The paper is devoted to the erection of modern reinforced concrete poles to power transmission lines. The durability of those poles is comparable to the service life of metal poles while the cost is half. Sectionalization of spun concrete poles simplifies their transportation. New solutions for erecting power transmission poles on foundations raise the height of conductors’ suspension. Thus, new reinforced concrete poles are capable to replace metal structures effectively in more than 60% of cases. Modern typical projects for overhead transmission lines can be incorporated into a single digital space of power line design, where necessary information will be present for all interested units throughout the entire life cycle of the facility

NPO Streamer JSC

On April 21-23, 2020, St. Petersburg will host the VII Russian Conference on Lightning Protection organized by NPO Streamer JSC. It will be held at Astoria Hotel. Preparations for this event have already started – the Company used the experience of previous conferences to make the event even more interesting and informative the next year.

Izolyator Company

For more than 120 years of its history, Izolyator plant has produced more than 620,000 high-voltage bushings, operating in the vast majority of power facilities in Russia and the CIS countries, as well as in 30 countries of the world. Due to active research and development activities, continuous expansion of international relations both in business and in engineering direction, the company is constantly improving its products, offering perfect innovative solutions, which provide the highest level of reliability.

THE ISSUE: Moisture is threatening the transformer. Moisture is one of the major cause of failures for power transformers and one of the main degradation factor for the insulation paper. It is therefore increasing the risks of operation failures and shortening the life expectancy of the asset.
