- 1. PRESENTATION ONCAPTIVE THERMAL POWERPLANT OF WAVE INDUSTRIES DHANAURA By : VAIBHAV KUMAR IV YEAR , VII SEM ELECTRICAL ENGINEERING
- 2. INTRODUCTION OF CAPTIVE THERMALPOWER PLANT
- 4. This plant has only one unit of 30 Mw .
- 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.
- 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 .
- 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 .
- 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.
- 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.
