Technological Development and Innovation

Two 110/10 kV power transformers of 25 MVA each are installed.

SF6 switchgear of 110 kV is used.

The facility uses advanced information technology and control systems and tools (relay protection and automation (RPA) solutions, emergency control automatics, data acquisition and transmission system, automatic information and metering system for commercial electricity metering), which ensure the processes of information exchange between the substation elements and the information exchange of the substations with external systems, as well as the control of the substation itself in digital form based on the protocols of IEC 618501 International Electrotechnical Commission Standard for communication networks and systems at substations, which specifies data streaming formats, form of information, rules of definition of power facility items, and a set of rules to arrange an event-related data transfer protocol.  standard.

The main and backup digital data transmission channels from the substation were established on the domestic transport digital equipment NATEKS FOM-16E1, which in 2020 was put into trial use as part of a pilot implementation at the facilities of Rosseti Kuban and launched into commercial operation

Deadlines: 2020–2022

In the reporting period, front-end engineering and design work was carried out, the decentralized architecture No. 3 for building digital substations was determined using sections IEC 61850–8-1 and IEC 61850–9-2 of IEC 61850 standard, the volume and type of equipment was defined. A feasibility study was made to compare the designed facility and the classic analogue adopted for comparison.

The expected effect of implementation:

• experience in design, installation and setup of IEC 61850 compliant equipment at 110 kV substations;
• upskilling of customer services concerning digital substations;
• reduction of costs for design, construction, installation and commissioning due to unification of microprocessor devices and reduction of cable connections for 110 kV substations;
• improving the safety of the facility maintenance by operating personnel.

Deadlines: 2020–2030

In the reporting period, innovative smart metering devices were introduced in six branches of Rosseti Kuban: Adygea, Armavir, Krasnodar, Leningrad, Sochi and Tikhoretsk power grids. In these branches, except for the latter, as part of the creation of a distributed automation system in 6–10 kV distribution grids, the investment program for 2021–2022 included projects to establish digital RES.

The project aims to create a smart metering system, integration into the established innovative systems: collecting and displaying information (SCADA), managing grid operating modes (DMS), managing grid operations (OMS).

The expected effect of implementation:

• reduction of operating costs by taking the readings and power supply parameters for electricity consumers remotely;
• the possibility of remote limitation and resumption of power supply to electricity consumers.

Deadlines: 2020–2022

In the reporting period, the Development Plan for the Production Asset Management System of Rosseti Kuban was approved for 2020–2022 (Minutes of the meeting of the Board of Directors No. 402/2020 dated September 14, 2020). The Company’s PAMS Development Plan for 2020–2022 includes 28 activities, including 15 activities related to PAMS development in terms of process automation, and 13 organizational activities. It is envisaged that PAMS will be integrated with the digital information systems of the Company.

The expected effect of implementation:

• ensuring the power supply reliability level established by the regulator;
• improving the efficiency of operating costs associated with production processes.
