Research and development

The Company’s innovative development programme focuses on research and development (R&D) meant to promote cutting‑edge technologies to create fundamentally novel methods, as well as applied research meant to improve the existing technologies.

Four R&D themes were finalised in 2022–2024. In 2024, phases of two R&D projects were accepted.

R&D results in 2024

R&D description	Technical result
Transition to smart grids with a distributed intellectual automation and control system
Research into the possibility of using the FCC frequency range for PLC in low‑voltage power grids for data transmission from smart electricity meters	Implementation timeframe: 2024–2025 Results obtained: State standards and regulatory documentation of Rosseti PJSC on signal transmission via low‑voltage power grids were reviewed A patent search was conducted in domestic and foreign databases in the field of the scientific work under study Technologies ensuring signal transmission in authorised frequency bands with authorized signal levels were analysed Particular technical requirements for hardware and software were developed for prototypes of smart electricity meters (SEMs) with PLC (FCC + CA) and the capability to switch the PLC frequency range via a backup RF channel Design documentation was developed for SEM prototypes with PLC (FCC + CA) 140 SEM prototypes were developed, manufactured and configured with PLC (FCC + CA) and the capability to switch the PLC frequency range via a backup RF channel Individual SEM prototypes with PLC (FCC + CA) were tested in laboratory conditions to check for proper functioning and switching of PLC frequency ranges
Application of advanced technology solutions and materials in power engineering
Research into the prospects for using high‑temperature wires, taking into account the shift of peak loads to periods of extremely high temperatures and the influence of temperature on the transmission capacity of OHLs	Implementation timeframe: 2024–2026 Results obtained: Patent searches and patent studies were carried out, and patent‑protected technical solutions related to R&D and the relevant regulatory framework were analysed The climatic conditions, temperature and load regimes of existing overhead lines and bus arrangements were analysed, and typical OHLs for the power system were selected as reference models for R&D Research on optimising the design and material of OHL wires for use in extreme weather conditions was analysed Test programmes and procedures were devised, and test equipment was selected Test benches were debugged and the procedure was tested using AC wire as a reference one

As a result of R&D work carried out in 2022–2024, four protection documents were obtained: three certificates of state registration of computer software and one certificate of state registration of a database. During the above period, six licence agreements for R&D results were concluded, and one R&D result was integrated into the production activities of the Company.
