How DRSK is changing the power grid complex of the Far East due to the new construction of power lines and substations
Every year the business attractiveness of the Far East becomes higher, and this is not happening without the participation of power engineers. Today, the power grid infrastructure in the region for priority development areas is created by the Far Eastern Distribution Grid Company (DRSK). The company is currently working with ASEZ in the Amur and Jewish Autonomous Regions, Khabarovsk Territory, and is also developing the integrated entertainment zone Primorye and the Power of Siberia gas project. The facilities under construction and already commissioned for residents of the ASEZ, small and medium-sized businesses are of great economic and social importance, solving the problem of connecting new ones and increasing the reliability of power supply to existing consumers.
Today, the Primorsky Branch is building new and modernizing existing power facilities with a total capacity of 75,5 MVA as part of the 2020 investment program. More than 1,2 billion rubles will be allocated for the implementation of all measures.
“DRSK has already started reconstruction of the 110 kV Muraveika substation in the suburb of Vladivostok. The work is carried out within the framework of the technological connection agreement between DRSK JSC and Primorsky Krai Development Corporation JSC. Reconstruction of the Muraveika substation is the second stage of work on technological connection of the facilities of the integrated entertainment zone, ”the company said.
The project provides for the expansion and increase in the capacity of the existing substation: installation of a third power transformer with a capacity of 16 MVA, as well as installation of an additional 6 kV switchgear. It is planned to complete construction and installation work at the power facility by the end of this year. The additional capacity of the Muraveika substation will ensure the further development of the entertainment zone.
In the spring of 2020, as part of the first stage of technological connection, the Primorsky branch of the DRSK built 8 6 kV cable lines with a length of about 80 km and installed four distribution points.
Also, within the framework of the investment program, the building is being reconstructed on the territory of the administration office of the Primorskie Electric Networks branch to accommodate a network control center. It is planned that by the end of the summer the construction and installation work will be completed. The center will receive modern software, which will allow real-time control of equipment of all voltage classes, provide information exchange with external related structures, coordinate the work of operational teams.
One of the key objects of investment activity of the Khabarovsk branch of the DRSK in the past few years has been the electrification of priority development areas. And the task for the coming months is to provide uninterrupted power supply to the Innokentyevka site, where in the medium term the existing fish processing base will be modernized, a modern cannery and a waste processing workshop will be built.
“An agreement has already been concluded for the technological connection of the site between the branch and the Corporation for the Development of the Far East (KRDV), as well as the design and estimate documentation of the facility and an agreement for the construction and installation,” the DRSK reported.
According to the technical requirements of the agreement, by the end of 2020, about 110 km of 10 kV overhead line will be built from the 10 kV Mago substation to the KRDV facilities.
In general, in 2020 the Khabarovsk power engineers plan to master work on several objects at once. Among them is the 35 kV Tishkino substation in the Vaninsky municipal district. Also, as part of the investment program of the Khabarovsk electrical networks, work will continue on the large-scale reconstruction of the 35 kV SDV SS, which supplies the southern and central districts of the regional capital. As a result of the modernization, the capacity of the substation will more than double, which will ensure a high degree of reliability of power supply to new residential areas: the Yu-City and Petroglyph Park complexes. In addition, this year will begin a large-scale renovation of two more power centers in Khabarovsk - the 110 kV Amurkabel SS and the Vostochnaya 110 kV SS.
So, according to the plan of power engineers for the next three years, the oldest substation in the city, put into operation 65 years ago, the 110 kV Amurkabel substation, will actually be rebuilt anew. And at the 110 kV Vostochnaya SS, an increase in transformer capacity by 5 MW is envisaged to connect new power receivers.
In the Amur Region, the DRSK branch completed the construction of a new 110/10 kV Maslozavod substation and two 110 kV power transmission lines for the Belogorsk ASEZ. The work was carried out within the framework of the technological connection agreement concluded with the KRDV. For two years, the Amur Electric Grids have built new power facilities and provided the required capacity for the oil extraction plant - one of the residents of the ASEZ "Belogorsk".
At the first stage, Amur Electric Networks in September 2018 completed the reconstruction of the 35/10 kV Promyshlennaya substation in the city of Belogorsk. In March 2019, according to the schedule approved by the parties, an additional 10 kV power transmission line was built to increase the connected capacity by another 2 MW. Construction of a 110/10 kV substation, two 110 kV overhead lines and one 10 kV overhead line is the third stage of the contract, which was implemented in July 2020 and increased the power output to 7,24 MW.
In addition, work is underway in the city of Svobodny. The Government of the Amur Region has included measures in the scheme and program for the development of the electric power industry of the Amur Region for the period 2020-2024. In Svobodny, significant infrastructure development is envisaged with the construction of new consumers. In the microdistrict in the northern part of the city, in addition to apartment buildings, it is planned to build a maternity hospital, a school, a hospital, shopping centers, production facilities, and facilities of Russian Railways.
In 2019, DRSK built almost 39 km of 0,4-10 kV power transmission lines in the city, installed 12 new 10 / 0,4 kV transformer substations and replaced five transformer substations with an increase in capacity.
“The city of Svobodny and Svobodnensky is among the top three municipalities in the Amur Region in terms of the number of applications for technological connection. Today the city is becoming the industrial center of our region, which means that the social infrastructure is also developing, we see this from the incoming applications for connecting new objects to the power supply. Out of 206 contracts for technological connection to our networks in 2019, 50 are for the connection of socially significant facilities, construction sites, production bases. We are carrying out all this construction within the framework of our investment program, but Svobodny's energy capacities have been exhausted, so the construction of new power facilities is required, ”says Evgeny Semenyuk, director of the branch of JSC“ DRSK Amur Electric Networks ”.
A free person within the framework of the Unified Subsidy (funds from the federal budget, which are directed to “social development of centers of economic growth - editor's note), will be allocated federal money for the development of power facilities in the city. With these funds, the Amur branch of the DRSK is to build a new power center with a voltage of 110/35/10 kV. Together with the mayor's office of the city of Svobodny, a land plot for the construction of a new facility and a preliminary route for the passage of a 110 kV overhead line have already been selected.
A large amount of work is also related to the connection of the Power of Siberia gas pipeline facilities. The supply of blue fuel from Russia to China began in December 2019. It is planned to supply five billion cubic meters of gas to China through Power of Siberia in 2020, ten billion cubic meters in 2021, and 2022 billion cubic meters in 15. The maximum capacity the gas pipeline should reach is 38 billion cubic meters of gas per year.
The decision to prepare the DRSK for energy infrastructure for construction sites in the southern part of the Republic of Sakha (Yakutia) was made about four years ago. Then the Yakut branch of the DRSK received nine applications from gas workers for the technological connection of these facilities.
“For ten years we have not had such a large consumer, and we have even slightly lost our potential. However, in 2016, a lot of preparatory work was carried out to implement a huge program of innovations in the energy infrastructure for the main gas pipeline, ”said the director of the Yakut branch, Alexander Kulemin.
If we talk in aggregate about already implemented projects, then power engineers can rightfully call the completion of the construction of eight along-route lines with a voltage of 6/10 kV with a total length of more than 36 km in the Aldan and Neryungri regions. All objects are implemented for uninterrupted power supply of line production control bases, connection points for cleaning devices and gas distribution stations.
The construction of a 220/10 kV substation KS-3 "Amginskaya" is nearing completion. The new power facility, worth more than 600 million rubles, with a transformer capacity of 20 MVA will provide power supply to the along-route lines of PJSC Gazprom and compressor station No. 3 Amginskaya.
Also, measures are being taken in the Neryungri region for the construction of a 220/10 kV substation KS-5, the commissioning of which is scheduled for 2020. The consumer will receive a total of 15 kW. Today, this work of power engineers is maximally aimed at achieving results in fulfilling the obligations of the grid organization under contracts for technological connection, with strict adherence to deadlines and technical regulations.
The DRSK will complete the full range of works on the creation of an external power supply scheme for the gas pipeline in the south of Yakutia by April 2022. Power engineers are confident that with the arrival of gas there will be an impetus in the social and industrial development of the Aldan and Neryungri regions.
