Electrical system in MIT, Manipal University, India

  1. 1. SOURCES UTILISATION & EXPENDITURE
  2. 2. BASIC ELECTRICAL POWER SYSTEMS & PRODUCTION OF ELECTRICITY IN KARNATAKA
  3. 3. Power System Components  Generation subsystem  Transmission subsystem  Distribution subsystem  Protection & control subsystem Most complex man made system !!
  4. 4. Basic Power System Structure
  5. 5. STATUS OF ENERY SECTOR IN KARNATAKA  State has no deposits of coal or petroleum, and therefore has to import it .  The electricity source for Karnataka has a mix of hydel, thermal and wind and accounts for 56% of the commercial need.
  6. 6.  In Karnataka, non-commercial energy sources like firewood, agricultural residues, charcoal and cow dung account for 53.2% which demonstrates a high dependency on biomass to meet rural energy needs.
  7. 7. Power Projects in Karnataka
  8. 8. TRANSMISSION OF POWER  The Karnataka Power Transmission Corporation Limited, also known as KPTCL is the sole electricity transmission and distribution company in state of Karnataka.  KPTCL buys power from power generating companies like Karnataka Power Corporation Limited (KPCL) and other IPPs and sell them to their respective ESCOMS
  9. 9.  Bangalore Electricity Supply Company.  Mangalore Electricity Supply Company ( Mescom ).  Hubli Electricity Supply Company.  Gulbarga Electricity Supply Company.  Chamundeshwari Electricity Supply Company. ESCOMS UNDER KPTCL
  10. 10.  Primary source :- MESCOM (State Supply)  Secondary source :- PRIVATE D.G SETS
  11. 11. Heart of the electrical system
  12. 12.  Basic function of power house is to synchronize and provide a continuous supply of electrical power.  It takes power from state supply, steps it down and then transmits it to the location of load.  In case of power failure it automatically starts the D.G sets which compensates for the failure of power.
  13. 13.  Location:- behind cafeteria  Supplies to:- AB-1,AB-2,AB-3,AB-4 WORKSHOP, LIBRARY.  State Supply :- 200A at 11KV  Generator Capacity:- 4 units of 415V, 500KVA POWER HOUSE 1:-
  14. 14. POWER HOUSE :- 2  Location :- 9th block  Supplies to:-8th,9th,10th,11th,12th hostel block, Annaporna mess, Waste water plant.  State Supply:- 200 A at 11KV  Generator Capacity:-2 units of 320 KVA, 415 V
  15. 15. POWER HOUSE 3:-  Location:- near Venugopala temple  Supplies to:-Staff quarters, swimming pool, temple,K block hostel  State Supply:-200 A at 11KV  Generator Capacity:-320KVA, 415V
  16. 16. POWER HOUSE 4:- Location:- Food court  Supplies to :-5th,6th,7th,13th block hostel, Food court, AC plant  State Supply:-400A at 11KV  Generator Capacity:-2 units of 500KVA, 415 V
  17. 17. POWER HOUSE 5:-  Location :- In front of 16th block  Supplies to:- 14th,15th,16th,17th block hostel, AC plant  State Supply:-400 A at 11 KV  Generator Capacity:-2 units 500 KVA, 415 V
  18. 18. POWER HOUSE 6:-  Location :- AB 5  Supplies to:-AB 5, AC plant  State Supply:-200 A at 11KV  Generator Capacity:-2 units of 625 KVA, 415 V
  19. 19.  Transmission losses account for 5% of the units consumed.  Power Houses are to maintain an optimum value of power factor so as to minimize the losses , failing to which supply of power by state is stopped automatically.  Unit-KWh number of kilowatts consumed in an hour.
  20. 20. Mescom Supply-stepped down by transformer.
  21. 21. D.G set – from outside
  22. 22. Inside a D.G set- the diesel engine
  23. 23. Instrument panel
  24. 24. Instrument panel
  25. 25. Cooling Tank
  26. 26. Exhaust Pipe
  27. 27. TRANSMISSION
  28. 28.  Consumption of power is calculated into three different categories :- 1.Hostel 2.College 3.Quarters  Total units consumed is calculated as the sum total of units taken from state supply, total units generated from D.G sets and units lost during transmission.

  37. 37. CONCLUSION
  38. 38. A Step Ahead…..  The Manipal University (MU), has embarked on a joint project with the Advisory Services in Environmental Management to develop the MU campus into an Eco-City.  ASEM is a joint programme of the German Technical Cooperation (GTZ) and the Indian Ministry of Environment and Forests  The identified goals are, alignment to ISO 14001 and trainings on energy conservation, sustainable design and Eco-budgeting  A training centre on Urban Sustainability Management would also be established to provide courses on Urban and Environmental Management.  The project takes a two-winged approach: on the one hand, promoting the establishment of an ISO 14001 certified environmental management system on campus will directly impact the academy’s resource use and environmental performance, while on the other hand, catalysing the setup of a study scheme on environmental management via international university partnerships serves to multiply environmental management capacities beyond the campus itself.
  39. 39. Efforts made by MIT  a) Up gradation of air-conditioning system It includes replacement of old air-conditioning units with power efficient water cooled screw chillers, cooling tower upgrades, unitary air- conditioner controls, implementation of building automation system, with sensors installed in entire building for efficient cooling, automatic switching ON/OFF based on occupancy and fixed time schedule, use of R - 138 gas system (environment friendly).
  40. 40.  b) Solar Water heaters Since the coastal belt of Karnataka is blessed with bright and sunny days almost throughout the year excepting the monsoon season, solar energy is in abundance and can be captured to meet our heating needs.
  41. 41. Awards and Recognition  2008-2009 : - Certified as an ISO 14001:2004 Organisation  2004-2005 : - Rajiv Gandhi Parisara State Award  2002-2004 : - District Award for Environment- first prize  1999-2000 : - District Award for Environment- first prize
  42. 42. Let start a new beginning….. with hope of a new and smarter world…. THANK YOU.
