The most important challenge of JSC Lenenergo is creation of new power network infrastructure on the basis of innovative development, upgrade and improvement of applied technologies. In the field of technological development the Company aspires to adopt the best Russian and foreign experience.
In 2013 the Board of Directors of JSC Lenenergo approved the Regulations of JSC Rosseti about uniform technical policy in the power network complex (further – the Regulations) as the internal document of the Company (Minutes # 19 of the meeting of the Board of Directors of JSC Lenenergo of 30.12.2013). All projects of JSC Lenenergo on new construction and reconstruction included in the investment program of JSC Lenenergo are implemented with observance of the requirements of uniform technical policy.
The goal of uniform technical policy in the power network complex consists in ensuring increase of reliability and efficiency of functioning of the power network complex in short-term and medium-term prospect at maintenance of the appropriate level of industrial and environmental safety on the basis of the innovative principles of development providing non-discriminatory access to electric networks to all participants of the market.
A specialized scientific and technical council (STC) which considers the issues of research and development, trial operation of equipment and materials during its sessions operates in JSC Lenenergo. In 2013 five sessions of STC were carried out.
Research and development works (R&D)
Trial operation of equipment, materials and technologies
Questions of use of the equipment
1) Results of completed R&D:
2) Development of R&D plan of JSC Lenenergo for 2013–2017.
1) Results of trial operation of overstrain limiters 110 kV produced by LLC Tavrida electric SPB in JSC Lenenergo branch – St. Petersburg high-voltage electric networks.
2) Application of non-insulated wire from a heat-resistant aluminum-zirconium alloy of ASPT brand on CL 35–110 kV limited on capacity.
1) Application of self-bearing insulated and protected wires and cables of 0.38–35 kV in the conditions of rural territories and city building in the territory of the Leningrad Region.
2) Use and experience of application of arc-suppressing reactors for ground compensation of single-phase short circuit currents (RDMR-485/10-U1 on substation # 166, etc.)
The technical policy is implemented in JSC Lenenergo on a number of key directions, including application of new technologies and equipment in various segments of activity.
Distributive networks 0.4–10 kV
Distributive networks 35–110 kV
RPAE, DOCS, communication, telemechanics
In 2013 JSC Lenenergo proceeded with implementation of a series of projects within uniform technical policy, including the program of renovation of cable networks 6–110 kV and the program of renovation of cable network 6–110 kV in St. Petersburg, financed by federal budget funds. In 2013 the Company launched implementation of the investment project “Complex development of electric networks of Petrogradsky district of St. Petersburg”.
JSC Lenenergo activity in the field of trial operation of equipment is regulated by the Regulations on introduction of new equipment and technologies in trial operation, approved by Order of JSC Lenenergo # 758 of 29.12.2012.
