Introduction of new technologies and equipment performed with a view of implementation of the technical policy:

  1. Monitoring of cars of operational-outreach crews (OOC) by means of GPS-GLONASS systems.
    JSC "Lenenergo" implemented the monitoring of OOC cars by means of GPS- GLONASS systems, which:
    • Determines on-line location of vehicles on a detailed digital map;
    • Performs complete control of movement on a route (run, fuel consumption, speed mode) both on-line and off-line.
  2. At present, the following gas-insulated equipment is installed in JSC "Lenenergo" substations:
    • 761 switches of 6-10 kV;
    • 44 switches of 35 kV;
    • 148 switches of 110 kV;
    • GISWG-110kV on 110 kV substation No.65 "Strelna", 110 kV substation No.14 "Baltiyskaya", 110 kV substation No.34 "Mirnaya", 110 kV substation No.140 "Rizhskaya", and 110 kV substation No.167 "Volkovskaya".
  3. The program on replacement of fuel-filled high-voltage inputs of power transformers on high-voltage inputs with firm isolation.
    The program on replacement of transformer inputs was calculated until 2012. During 2008-2009, replacement of 111 inputs was conducted. In 2010, the plan on replacement of inputs in the quantity of 60 pcs in seven power network enterprises (VPDN - 3 pcs, GPDN- 9 pcs, KnPDN-12 piece, LpPDN - 6 pcs, NlPDN - 6 pcs, SbPDN-12 piece, TkPDN - 12 pcs) was executed
  4. The program on replacement of switching devices of power transformers.
    The purpose is enhancement of the resource of work of power transformers at the expense of replacement of the "weakest" element. Systematic replacement of morally and physically outdated RVT with more modern of MR and ÐÑ-9 types will allow considerably raising the reliability of work of transformers and to improve the quality of electric power. Five RVT were replaced in 2009, and three RVT in 2010.
  5. JSC "Lenenergo" widely implements self-supporting insulating wires (SSIW) on OTL 0.4-10 kV.
    There were reconstructed 2,043 km of OTL 0.4-10 kV with application of self-bearing isolated wire. For now, there is developed and approved the medium-term program of replacement of non-isolated wire on SSIW in 0.4-10 kV networks with the term of implementation 2010-2012. The total amount is 344 km in eight power network enterprises.
    The program of 2010 of the planned volume of 105.2 km (95 km on OTL 6-10 kV and 10.2 km on OTL 0.4 kV) was executed completely. It covered six power network enterprises: VPDN – 17.3 km (11.1 km - OTL 6-10 kV and 6.2 km OTL 0.4 kV), LPDN – 4 km (OTL 0.4 kV), LpPDN – 37 km (OTL 6-10 kV), KnPDN – 19.1 km (OTL 6-10 kV), SUPDN – 15.3 km (OTL 6-10 kV), TkPDN – 12.5 km (OTL 6-10 kV).
  6. JSC "Lenenergo" started to perform diagnostics of 6-110 kV cable lines by sparing and non-destroying methods.
    With a view of development of modern diagnostic tools JSC "Lenenergo" in 2010 successfully proceeded with working off of essentially new methods of diagnostics of the condition of 6-110 kV cable lines: testing by voltage of ultralow frequency of 0.1 Hz, measurement and analysis of returnable pressure, reflectometry - the method of measurement and localization of partial categories. It allowed JSC "Lenenergo" management to develop and approve the new normative document "Volumes and rates of sparing and not destroying test methods and diagnostics of cable lines of 6-110 kV". The document purpose is to reduce damage of 6-35 kV cables at scheduled-preventive testing and to reduce costs for carrying out of repair work of 6-35 kV cable lines, and to raise reliability of electrical supply of consumers in St. Petersburg and the Leningrad Region.
    The developed volumes and rates of sparing and not destroying test methods and diagnostics of 6-110 kV cable lines can be applied at development of normative documents on diagnostics of cable lines of the power industry of the Russian Federation.
    For the given development, JSC "Lenenergo" was awarded by the 1st place diploma in the Competition on quality "Made in St. Petersburg-2010" in the nomination "the Best project in the field of electric equipment monitoring", and by the Quality symbol "Made in St. Petersburg".
  7. Laser aero-scanning of OTL 35-110 kV
    In 2010, laser aero-scanning of 184 km of OTL 35-110 kV for the purpose of determination for over-sizes, and reception of 3D models of air-lines was produced. Carrying out of aero-scanning of OTL 35-110 kV allows estimating technical condition of facilities, to reveal deviations of dimensions of a line from legislative effects, and also to optimize routes for accomplishment of emergency flights over OTL that essentially reduces the carrying out time of emergency-recovery work.
  8. The target program on installation of reclosers on OTL 10 kV
    In 2009, there was developed the target medium-term program on installation of vacuum reclosers by RVA/TEL-10-12.5/630 U1 on OTL 10 kV. According to the program:
    • In 2007-2009, there were installed 54 reclosers in JSC "Lenenergo" under the program of increase of reliability.
    • In 2010, there were placed in operation 38 reclosers in eight power network enterprises (VPDN - 4 pcs, GtPDN-3 pcs, KnPDN-6 pcs, LPDN - 5 pcs, LpPDN – 5 pcs, NlPDN – 5 pcs, SPND - 4 pcs, TkPDN - 6 pcs).
    • In 2011 it is planned to install 41 reclosers.
    • In 2012 it is planned to install 43 reclosers.

    Installation of reclosers allows allocating in case of accident of the damaged site without switching-off of other consumers, to partition OTL 10kV with provision of AR and ALT functions that considerably raises reliability of electrical supply of consumers, reduces short of supply of electric power and reduces time of search of the place of damage and its elimination.
    The management of reclosers (inclusion, de-energizing, and change of options) occurs remotely via GSM-communication channels, without departure of the operatively-repair personnel to the installation site.
  9. Installation of boosters.
    In settlements, where actually there is a question of voltage quality in 0.4 kV networks, installation of boosters may become one of the decisions – application of voltage stabilizers in 0.4 kV networks allows:
    • Automatically raising or lowering voltage to the set parameters.
    • Eliminating asymmetry of voltage on phases, including at loading change.
    • Excluding increase of voltage at consumers at breakage of a zero wire.

    In JSC "Lenenergo" branch "Kingisepp Power Networks" in 2008 there was entered into pre-production operation (in Pondelovo settlement) of the booster STS-5-63 380 UZ by capacity of 63kVÀ. It was completely adjusted in 2009, and till now there were no remarks on its operation.
  10. Modular mobile substations (MMS) of 110 kV.
    For possibility of connection of additional capacity to 110 kV SS and for unloading of the "overloaded" equipment in 2010 modular mobile substations (MMS) was installed on 110 kV SS of JSC "Lenenergo" branch "SuPDN":
    • On SS No.212 – 2 MMS of 110 kV;
    • On SS No.90 – 1 MMS of 110 kV;
    • On SS No.92 – 1 MMS of 110 kV;

    Two additional MMS were bought – the place of planned installation of the MMS taking into account of the prime requirement is now specified. The total quantity of 110 kV modular mobile substations acquired by this time constitutes 14 pcs of the rated power capacity of 25 ÌVÀ each.
  11. Modular 10 kV disconnector of "cutting" type.
    In the Company branch "Kingisepp power Distribution Networks" in 2009 there was installed in pre-production of the operation 10 kV modular disconnector of external installation of "cutting" type RMNZS-2-10/630-2 (by the manufacturer "NPO Pribor", St. Petersburg), declared as possessing of raised reliability and working capacity. In the course of pre-production operation Kingisepp power Distribution Networks have improved the given device that was positively accepted by the manufacturer for completion of its design. At present, there are no remarks on its work.
