  1. PROJECT REPORT ON POWER AND UTILITY SECTOR BY YUGANK SHARMA B-TECH IVYEAR YAGYAVALKYA INSTITUTE OF TECHNOLOGY

  2. CONTENTS • HISTORICAL INTRODUCTION OF IOCL. • SAFETY MEASURES. • UNITS OF IOCL REFINERY. • POWER AND UTILITY DEPARTMENT. • CAPTIVE POWER PLANT. • HEAT RECOVERY PLANT. • CONTROL SYSTEM.

  3. HISTORY OF IOCL IN ASSAM • SEARCH OF OIL IN INDIA BEGAN IN 1866 WHEN ,MrGoodenough of Mckillop Stewart& co. drilled a well in jaypore in upper Assam . • By 1882 the Assam Railway & Trading Company struck oil in Digboi. In 1889 making the true begining of crude oil production. • In 1899 (AR&TC) promoted another company the Assam Oil Company(AOC). • Which in 1981 became Indian Oil Corporation Limited . • IOCL,DIGBOI is asia’s first oil refinery with a capacity of 0.5 million tons per year. • The place IOCL is established got its name from a story when an elephant ‘s feet got stuck in the mud and oil with water came up into the surface , a british army men noticed it and told a boy “digboy”.

  4. SAFETY MEASURES • SMOKING IS STRICLY PROHIBITED. • EMPLOYEES AND VISITORS SHOULD NOT BRING THERE MOBILES,LIGHTER OR ANY FLAMMABLE ITEMS. • HORSE PLAY INSIDE THE REFINERY IS NOT ALLOWED. • MUST WEAR HELMET AND SAFETY BOOTS WHILE DOING ANY OPERATIONAL JOB. • PHOTOGHAPHY INSIDE THE REFINERY IS NOT ALLOWED AS THESE MAY ALSO BE SOURCE OF FIRE. • THESE THINGS ARE STRICTLY PROHIBITED AS IT IS AN OIL REFINERY AND PRESENCE OF HYDRO CARBONS IS EVERY WHERE WHICH MAY CAUSE FIRE. • TRAINEE SHOULD NEVER BE ON FIELD WORK WITHOUT GUIDANCE OF ANY OPERATOR.

  5. UNITS OF IOCL REFINERY • CRUDE/VACUUM DISTILLATION UNIT(CDU/VDU). • CATALYTIC REFORM UNIT (CRU). • NEW DELAYED COKING UNIT(NDCU). • WAX HYDRO FINISHING UNIT(WHFU). • POWER AND UTILITY DEPARTMENT. • SOLVENT DE WAXING UNIT/DE OILING UNIT(SDU). • HYDRO TREATING UNIT.

  6. POWER AND UTILITY DEPARTMENT • IT IS RESPONSIBLE GENERATION,DISTRIBUTION AND MAINTENANCE OF ELECTRIC POWER SYSTEM. • IT HAS FOLLOWING SECTION. • CAPTIVE POWER PLANT. • HEAT RECOVERY AND STEAM GENERATION PLANT. • CPP CONTROL AND MONITORING SYSTEM. • ELECTRICAL POWER DISTRIBUTION SYSTEM. • PROTECTION SYSTEM.

  7. CAPTIVE POWER PLANT • THE GENERATION SCHEME IS OF CO- GENERATIVE TYPE. • IT HAS THREE GAS TURBINE PLANT OF 8.5MW AND ONE GAS TURBINE PLANT OF 20MW. • AT A TIME TWO GT TURBINE PLANT ONE OF 8.5MW AND 20MWGT TURBINE PLANT IS IN OPERATION. • THE PRODUCTION OF THE PLANT IS OF 11KV,WHICH IS STEP DOWN TO 6.6KV,3.3KV AND 415V. • TOTAL POWER GENERATION AT PEAK LOAD IS 14.56KW. • IT HAS TWO DIESEL POWER PLANT ONE OF 320KVA AND 500KVA FOR PROVIDING POWER TO THE STARTING MOTOR DURING EMERGENCY. • THE EXHAUST OF THE GAS TURBINE IS USED TO GENERATE STEAM FROM FOR REST OF THE REFINERY USE MAINLY FOR SDU AND WHFU PLANTS. • IT IS A DUAL FUEL SYSTEM THE GT RUNS ON MAINLY ON NATURAL GAS AND HIGH SPEED DIESEL IS IN EMERGENCY CONDITION.

  9. BASIC COMPONENTS

  10. BASIC COMPONENTS • Compressor • Draws in air & compresses it • Combustion Chamber • Fuel pumped in and ignited to burn with compressed air • Turbine • Hot gases converted to work • Can drive compressor & external load

  11. COMPRESSOR • Radial/centrifugal flow • Adv: simple design, good for low compression ratios (5:1) • Disadv: Difficult to stage, less efficient • Axial flow • Good for high compression ratios (20:1) • Most commonly used

  12. COMBUSTION CHAMBER • Where air & fuel are mixed, ignited, and burned • Spark plugs used to ignite fuel • Types • Can: for small, centrifugal compressors • Annular: for larger, axial compressors (LM 2500) • Can-annular: rarely used

  13. TURBINE • Consists of one or more stages designed to develop rotational energy • Uses sets of nozzles & blades • Single shaft • Power coupling on same shaft as turbine • Same shaft drives rotor of compressor and power components

  14. Split Shaft • Gas generator turbine drives compressor • Power turbine separate from gas generator turbine • Power turbine driven by exhaust from gas generator turbine • Power turbine drives power coupling

  15. SPECIFICATIONS • GENERATOR SPECIFICATION FOR 8.5MW GT. • MADE BY BHEL,HYDERABAD, • 11KV,10625KVA,50Hz,1500RPM,STATOR CURRENT 558A,CONNECTION-Y,INSULATION-E,PHASE-3,PF-0.8 • GAS TURBINE SPECIFICATION FOR 20MW AND 8.5MW. • 7100HP/6500LP,DUAL FUEL-NATURALGAS/HSD. • GENERATOR SPECIFICATION FOR 20MW GT. • 11KV,25.063MVA,50Hz,3000RPM,PF-0.8,1315A • 8.5 MW GT PLANT IS SINGLE SHAFT AND OTHER ARE DOUBLE SHAFT.

  16. HEAT RECOVERY STEAM GENARATOR PLANT

  17. HEAT RECOVERY PLANT • IT IS SINGLE PRESSURE ,NATURAL CIRCULATION, HORIZONTAL,SUPLEMENTARY FIRED,WATER TUBE, SINGLE DRUM ,HV TYPE. • NATURAL GAS IS THE FUEL FOR HEAT RECOVERY. • HEAT SOURCE IS THE GT EXAUST. • GT EXAUST GAS FLOW IS 386 TPH. • GT EXAUST GAS TEMP IS 511 DEG-C.

  18. FLUE GAS PATH B A C D E F G chimney A : Super heater 3 B : Duct Burner C : Super heater 2 D : Super heater 1 E : Evaporator F : Economizer G : Cond. Pre Heater

  19. CONTROL SYSTEM

  20. CPP CONTROL AND MONITORING • THESE SECTION IS DIVIDED INTO THREE PARTS. • MANUAL CONTROL SYSTEM. • DISTRIBUTED CONTROL SYSTEM. • ELECTRICAL CONTROL SYSTEM.

  21. MANUAL CONTROL SYSTEM • IN THIS SYSTEM MAN POWER IS USED. • THE OPERATORS IN THE CONTROL ROOM KEEP EYE ON THE PLANT AND IF ANY ALARM OCCURS THEY ORDER THE FIELD WORKERS TO TAKE ACTION. • THERE ARE 29 EXECUTIVE AND 174 NON EXECUTIVE MEMBERS.

  22. ELECTRICAL CONTROL SYSTEM • ELECTRICAL CONTROL SYSTEM IS USED FOR ON- LINE MONITORING AND CONTROLLING OF THE CPP AND ELECTRICAL CONTROL SYSTEM. • ECS MODE: THE BASIC OPERATIONAL PHILOSOPHY OF THIS MODE IS THE PLC(PROGRAMMABLE LOGIC CONTROLLER). • EACP MODE: THE BASIC OPERATIONAL PHILOSOPHY IS THE MIMIC MODE. • ALL THE ENERGY MANAGEMENT FUNCTIONS LIKE LOAD SHEDDING, SYNCHRONISATIONIS DONE BY THIS MODE . • EACP MODE ACTS AS BACK UP FOR ECS MODE.

  23. DISTRIBUTED CONTROL SYSTEM • THIS SYSTEM IS USED FOR FUNCTIONAL CONTROLLING AND MONITORING OF THE GT UNITS ,GENERATORS,DG SETS • THERE ARE SOME ELECTROMECHANICAL SYSTEM WHICH ACTS SENSORS IN THE SYSTEM WHICH SENDS SIGNALS TO THE CONTROL ROOM . • THIS MAKES THE OPERATOR TO WORK IN THE PLANT WHITH OUT GOING IN THE FIELD. • THIS FUCTION ON THE PLC MODE .

  24. DISTRIBUTION SYSTEM

  25. SUBSTATION

  26. LIST OF SUBSTATIONS

  27. PROTECTION SYSTEM RELAYS CIRCUIT BREAKER

  28. SAVE ELECTRICTY • THERE ARE MANY VILLAGES IN OUR COUNTRY NOT HAVING ELECTRICITY . • SWITCH OFF THE FANS AND LIGHT WHEN YOU DON’T USE IT .

  29. THANK YOU FOR YOUR PATIENCE HEARING
