1 Problems of power supply of the infrasound and seismic stations. The ways to solve them Special Monitoring Service of Ministry of Defense of Russian Federation Alexander Tarasov

2 1. Unavailability data of the IMS 19 % Power failure Other

3 2. Russian IMS stations Seismic primary array Seismic primary three-component station Infrasound station

4 3. The typical scheme of the PS IS power supply H 2 A 1 B 2 B 3 A 0 B 0 3km A 3 A 2 500m 3km H 1 H 0 H 3 B 1 PS IS CRF High voltage power transmission lines

5 4. Backup power supply scheme of the remote element External power supply network Batteries UPS/ Charge controller Station equipment Power supply scheme is the 3rd category object repairing time is 24 h and more

6 5. Unavailability data of the Russian IMS stations 17 % Power failure Other

7 6. The backup power supply requirement - External power supply quality; - Used batteries type; - Necessary batteries reserve (nominal capacity); - Batteries charge/discharge mode; - Timeliness and quality of operations; - Climate conditions.

8 7. Unavailability data of the stations IS45 (Ussuriysk) 15 % Power failure Other

9 8. The scheme of the power supply IS45 (Ussuriysk) H 2 H 0 3km H 1 H 3 CRF High voltage power transmission lines

10 9. The scheme of the backup power supply IS45 (Ussuriysk) External power supply network Batteries AGM60 UPS/ Charge controller SUNSAVER SS V Station equipment From 2008 to 2012 there were 45 main power supply failure cases with duration from several minutes to 72 hours

11 10. Modernization. UPS replacement (contract ) External power supply network Batteries AGM60 UPS/ UPS/ Charge Charge controller controller SUNSAVER K SS V Station equipment Wide range of input voltages Stabilization of the output voltages

12 11. Modernization. Battery replacement (contract ) External power supply network Batteries OPzV250 AGM60 UPS/ Charge controller SUNSAVER SS V Station equipment - Life cycle up to 15 years; - Work in standby mode; - Recover after deep discharge; - Reliable work in case of undercharge/overcharge; - High reliability and efficiency under the different conditions. Battery AGM 60 A*h does t work up 16 hours T = W U 1 + K P W = 60 А h 12 V = 1 + 0,25 36 W = 16 h Requirement's capacity 250 А*h 1 + K P T OPzV250 accumulator batteries are unattended, with gas recombination, lead-acid gel accumulators with ironclad positive plates U

13 12. Modernization. UPS replacement External power supply network Batteries OPzV250 UPS/ Charge controller K Station equipment It doesn t provide nominal charge characteristics of the OPzV250* *The manufacture recommended to use the UPS«K » with batteries«opzv250» in the backup power supply scheme

15 14. Climatic factor Belogorsky Monastery of St. Nicholas

16 15. Climatic factor

17 Russian winter Belogorsky Monastery of St. Nicholas

18 16. The required power of the heater Q т (kw) = (100 W/m 2 S (m 2 ) K 1 K 2 K 3 K 4 K 5 K 6 K 7 )/1000 S room area, S=5m 2 K 1 heat loss coefficient of windows, K 1 =0,85 (without windows) K 2 coefficient of wall heat losses, K 2 =0,854 (good insulation) K 3 coefficient the ratio floor area and windows, K 3 =0,7(without windows) K 4 coefficient of outdoor temperature, K 4 =1,7 (outdoor temperature -55, inside tempereture 10 ) K 5 the number of external walls, K 5 =1,2 K 6 type of room that are on calculating, K 6 =1,0 K 7 room height, K 7 =0,95 (the height is 2,0 m)

19 17. The required power of the heater Q т (кwт) = 500 Wт Methods of heating Convective Infrared

20 18. The maintain of the battery Battery check: Check the charge voltage of the battery Clean the conductive part Renovate corrosion-preventive compaund Prophylactic recuperation if it is necessary Suggests: To include these procedures in the station operator responsibility To equip the station by charge discharge device

21 19. Power supply PS34 (Norilsk) Located in the hard-access place from local power network 7 км

22 20. Power supply PS34 (Norilsk) Autonomous power generating units Autonomous backup 1 year Type 1 Type 2

23 21. Summary To modernize power supply systems To provide operating conditions Recommended operators to maintain the battery To consider possibility of the implementation of the independent power supply on the PS34 «Norilsk» The reliable station facilities power supply scheme organization would increase data availability which is the key factor of the IMS effitiency
