Power in the "digital"
The Far East turned out to be one of the advanced platforms for the introduction of digital solutions in the Russian electric power industry.
Among the tasks outlined by the May decrees of the President of Russia are the implementation of a comprehensive plan for the modernization and expansion of the trunk infrastructure, which includes, among other things, building intelligent control systems based on digital technologies for 2024.
Sell more expensive buy cheaper
“The volume of investments by energy companies in digital technologies is growing every year, and their role in the competition in the global energy markets is growing,” said Alexei Kulapin, Director of the Department of State Energy Policy of the Russian Ministry of Energy, at a meeting of the State Duma's Energy Committee in December. The regulator seeks to help companies, he added: The Ministry of Energy of Russia has prepared a departmental project "Digital Energy". The document provides, in particular, the creation of a system for coordinating the digital transformation of the Russian fuel and energy complex, conditions for the development and development of digital services and solutions in a single information environment, ensuring the digitalization of public administration and control and supervisory activities in the fuel and energy complex, the official added.
Full digitalization of Russian power grids will require an investment of RUB 2 trillion. - such data was provided by the Minister of Energy of the Russian Federation Alexander Novak. Digitalization must be singled out as a separate task, because the design of new equipment does not mean the automatic introduction of digital technologies, the Ministry of Energy states. The standardization of equipment is a rather conservative process, in practice the standards developed several years ago can be applied, the course towards digitalization allows to speed up the process, the ministry notes.
Digitalization applies to all energy sectors, recalls the director of the Institute of National Energy Sergey Pravosudov. In particular, Gazprom uses consumption and purchase accounting systems at its power generating and grid assets, which brings significant savings, the expert specifies. “Digital solutions allow us to directly enter the wholesale electricity market and sell there at a higher price, but buy at a cheaper price,” emphasizes Sergey Pravosudov.
In the leaders
The Federal Grid Company (FGC UES, operator of the Unified Energy System) plans to invest at least 10 billion rubles in digital projects in the next five years. per year, that is, about 10% of the total average annual investment program, these are the company's data. Among the priorities is the digitalization of the backbone power grids of the Far Eastern Federal District (DFO). Digitalization solutions are not isolated, they are being implemented in the current plans for the construction and modernization of power facilities, as follows from the materials provided by the company. This also applies to the most ambitious projects implemented in the Far East: modernization of transport systems (BAM, Transsib, ESPO), connection of priority development territories (TOP), provision of reliable power supply to centers of socio-economic growth (including Vladivostok and Khabarovsk).
The Far East was among the leaders in the implementation of the energy system digitalization program. So, in November, the System Operator reported on the introduction of digital technologies for managing energy regimes in Transbaikalia and Buryatia (the regions became part of the Far Eastern Federal District at the end of 2018). In the Far East, a number of major projects have been completed for laying fiber-optic communication lines on overhead power lines, added to FGC. We are talking about the transits Nizhniy Kurany - Maya and Nizhniy Kurany - Olekminsk in Yakutia (the distance is almost 1000 km). The total length of FGC UES fiber-optic communication lines in the Far East exceeds 11 thousand km, taking into account the Trans-Baikal Territory and Buryatia. "The development of a technological communication network serves as the basis for further digital transformation of the power grid complex, including the construction of digital substations and the introduction of telecontrol," says a company representative.
In the outgoing year, ten substations of FGC UES in the Far Eastern Federal District were transferred to telecontrol (in total, this technology has been implemented today at 24 facilities of the Unified National Power Grid in the country), follows from the materials of FGC. Among others, these are substations supplying Khabarovsk and Vladivostok, as well as the Bolshoy Kamen ASEZ (the Zvezda shipbuilding complex is located here). “The introduction of telecontrol can significantly improve the quality of power facilities. In particular, it provides a dramatic - tens of times - reduction in the time of scheduled switching. The risks of erroneous actions of personnel are reduced to a minimum, ”recalls the representative of FGC. All FGC facilities in the Far Eastern Federal District are provided with automated systems for commercial metering of electricity, according to the company's materials. This makes it possible to quickly identify power losses, make accurate balancing, and receive operational information about the operating modes of the networks, emphasizes the representative of FGC.
By 2021, telecontrol of substations will be implemented at 13 more FGC power facilities in the Far Eastern Federal District, including two links of the Primorsky 500 kV energy ring (Lozovaya and Vladivostok substations), as well as 220 kV substations at the ESPO oil pumping stations in the Amur Region and Yakutia, talk about their plans in the company. “In total, the technology will cover 23 power facilities of the Far Eastern Federal District - this is a quarter of the total number of substations of the Unified National Electric Grid, which will be transferred to telecontrol at the current stage,” says the FGC materials.
Another area of work is the construction of digital substations. In general, more than 2025 such projects are planned to be implemented in the Unified Energy Grid by 30.
In the Far Eastern Federal District, two 220 kV substations will be digitized - Blagoveshchenskaya (supplies the capital of the Amur Region) and Petrovsk-Zabaikalskaya (provides energy transit between Buryatia and the Trans-Baikal Territory, as well as power supply for the Transsib section). These are operating facilities, digital elements will be introduced as part of their reconstruction. The use of digital substation technologies will reduce operating costs by up to 40% due to timely equipment diagnostics and remote monitoring, the transition from preventive maintenance to condition-based maintenance, and a reduction in the number of operating personnel, follows from the company's materials. At the same time, the risks of accidents are minimized.
Digital solutions can be expressed not only in automation and algorithms. So, in the outgoing year, FGC conducted a survey using drones on 45 power lines in the Far East with a total length of 5,5 thousand km - this is the largest volume among the macro-regions of the company. The surveyed infrastructure participates in the power supply of the facilities of Russian Railways and Transneft, in the scheme of power delivery to the largest power plant in the Far Eastern Federal District - Bureyskaya HPP. Based on the data obtained, a high-precision 3D model of the landscape and the power lines themselves will be created. This will help to analyze the state of the infrastructure and make the best decisions on issues related to its repair or reconstruction.
Thanks to the implementation of digital solutions in the complex of the largest projects in the Far Eastern Federal District, a modern infrastructure is being created that makes it possible to respond to the growing demands of consumers for the quality and efficiency of power supply, as well as to form the basis for the further development of the region.
Digitalization is certainly beneficial for companies, but as a business process, digitalization has never been miscalculated, says Sergei Pikin from the Energy Development Fund. Of course, it is important to improve the quality of electricity supplies, reduce losses, and minimize the risks of accidents. But the main profit of the company comes from the restructuring of their own business processes on the basis of digitalization, the expert says: "The quality of management is growing, the company starts to work differently, the shareholders see it immediately."
