  • 1. PRESENTATION ONCAPTIVE THERMAL POWERPLANT OF WAVE INDUSTRIES DHANAURA
    By : VAIBHAV KUMAR
    IV YEAR , VII SEM
    ELECTRICAL ENGINEERING
  • 2. INTRODUCTION OF CAPTIVE THERMALPOWER PLANT
  • 3. *GENERATING POWER*
    • The power output of generator is 30 MW at 11 KV.
    • 4. This plant has only one unit of 30 Mw .
    • 5. It import electricity during maintenance .
  • *BASIC COMPONENT*
    Generator
    Steam Turbine
    Boiler
    Electrostatic Precipitator
    Power X-mer
    Cooling Tower
    Switch Yard
  • 6. *ALTERNATOR*
    Alternator is directly coupled with turbine and it convert mechanical energy into electrical energy. In this plant water cool alternator is used for generating electricity . Excitation system of alternator is brushless.
    ALTERNATOR SPECIFICATION FOR 30MW .
    11KV , 37.5MVA , 50Hz , 1500RPM , CONNECTION-Y , PHASE-3 , PF-0.8.
  • 7. *WATER COOL ALTERNATOR*
  • 8. *STEAM TURBINE*
    • With the use of boiler and then Steam Turbine makes the plant efficiency better.
    • 9. The Steam Turbine comprises of one High Pressure Turbine and one Low Pressure Turbine.
  • 10. *BOILER*
    Water tube boiler is used in this plant. Steam pressure at inlet is 102 kg/cm² & steam temp. at inlet is 535˚C. In this boiler , water is flow in the tube in furnace . Steam produces in tube & it collect in a drum which is situated on the top of boiler . Then steam goes to turbine .
  • 11.
  • 12. *ELECTROSTATIC PRECIPITATOR*
    Electrostatic precipitator is consists of a large number of collecting electrodes. In it dust particles are charged and stick to the electrodes , hammer hit electrode and dust fall down . Dust is collect in base of ESP . Then dust is removed by air HOPPER. Transparent smoke find out in chimney .
  • 13.
  • 14. *POWER TRANSFORMER*
    To step-up or step-down the voltage and transfer power from one a.c. voltage to another a.c. voltage at the same frequency.
    TRANSFORMER SPECIFICATION :
    37.5MVA , 11/132KV , 50Hz , phases -3 , oil quantity-21725 ltr, cooling – ONAN:ONAF.
  • 15.
  • 16. *COOLING TOWER*
    There are X–flow method is used for cooling the circulating water .
  • 17. *SWITCH YARD*
    Basic Component Of Switch Yard:
    1. Isolator .
    2. Current x-mer.
    3. Potential x-mer.
    4. Circuit breaker .
    5. Lightning arrester .
  • 18. * ISOLATOR *
    These are used to disconnection transmission line under no-load condition for safety, isolation and maintenance.
  • 19. * CURRENT TRANSFORMER*
    These are used to step-down currents for measurement, control & protection.
  • 20. *POTENTIAL TRANFORMER*
    These are used to step-down voltage for measurement .
  • 21. * CIRCUIT BREAKER *
    These are used for automatic switching during normal or abnormal conditions . There are sf6 circuit breaker is used .
  • 22. * LIGHTING ARRESTERS *
    These are used to discharge lightning over voltages and switching over voltages to earth.
