    Kota Thermal Training report by Abhishk mathur Kota Thermal Training report by Abhishk mathur Presentation Transcript

    • A SEMINAR PRESENTATION ON Kota thermal power station ELECTRICAL ENGINEERING GOVERNMENT ENGINEERING COLLEGE ,AJMERGuided By :- Presented By :-Mr. K.G SHARMA ABHISHEK MATHURAssociate professor VII th semester Electrical Branch
    • KOTA THERMAL POWER STATION
    • REASON FOR CHOOSING KOTA FOR THERMAL PLANT SETUP Availability of large amount of clean cooling water required for the station. Location of station on broad gauge main Delhi- Mumbai Railway line Concentration of load in Kota city and Kota region. Constant power supply. Proximity to M.P. Coal fields. Transmission and Grid substation are quite nearer to the site.
    • INTRODUCTIONKSTPS is first coal based power plant in Rajasthan.It is located ideally on the left bank of CHAMBALRiver at the upstream of KOTA BARRAGE.Its first unit of capacity 110 MW is synchronized on 17jan 1983.It is one of highest power generating plant withinstalled capacity of 1240 MW.
    • DESIGN STAGES Stage V Stage IUnit 1 – 110 MW Unit 7 – 195 MWUnit 2 – 110 MW Stage II Stage III Stage IV Unit 3 – 210 MW Unit 5 – 210 MW Unit 6 – 195 MW Unit 4 – 210 MW110 + 110 + 210 + 210 + 210 + 195 +195 = 1240 MW
    • CONTENTS OF THE PRESENTATION• GENERAL LAYOUT• COAL HANDLING PLANT• PROCESS OF STEAM GENERATION• TURBINE• GENERATOR• SWITCHYARD
    • PLANT OVERVIEW
    • COAL HANDLING PLANT• Is called the HEART of thermal power plant because it provided the fuel for combustion in boiler.• The coal is brought to the KSTPS from BHARAT COAL LTD.• There are 14 tracks for transportation.• Everyday 3- 4 trains of coal are unloaded, each train consists 58 wagons.• Coal is unloaded from wagons by means of WAGON TRIPPLER
    • OVERVIEW OF COAL HANDLING PLANTRow coal from Bharat To KSTPS from gurla via Wagon trippler coal ltd. Dhanbad & a single railway track bilaspur(MP) Coal size reduced by 20 mm Bunkers Crusher house HoppersRow coal feeders CONVEYING SYSTEM Coal mills BOILER FURNACE TANGENTIAL FIRING OF PULVERISED (pulverization) COAL
    • PROCESS OF STEAM GENERATION K.S.T.P.S
    • TURBINE• Turbine is a machine in which a shaft is rotated steadily by impact of steam it converts heat energy into mechanical energy.
    • STEAM TURBINE BOILER & SUPERHEATERSTEAM AT545 C STEAM AT 535 C H P TURBINE REHEATER M P TURBINE STEAM ATSTEAM AT 545 C535 C L P TURBINE
    • TURBO GENERATORDesigned for continuous operation at the rated output.Directly coupled with steam turbine, rotated at high speedof 3000 RPM.Two major parts:-STATOR AND ROTORMajor parts of stator are Major parts of rotor are Stator frame Rotor frame Stator core Rotor Windings Stator bars Stator windings
    • SWITCHYARDThe 220 KV Switch yard is the main part of the KTPSit has two buses arrangement with a bus coupled breaker.There are 11 feeders connected at 220 KV switchyard
    • Main parts of Switchyard• CIRCUIT BREAKER• ISOLATOR• CURRENT TRANSFORMER• POTENTIAL TRANSFORMER• LIGHTNING ARRESTOR
    • CIRCUIT BREAKER Circuit breaker is basically a mechanical device used to make or break an electrical circuit under normal & abnormal condition. A circuit breaker is switched on or off under load conditions an arc is produced in between the breaker contacts. This arc produced between the breaker contacts is quenching by some suitable medium.
    • TYPES OF CIRCUITS BREAKERMINIMUM OIL CIRCUIT BREAKER SF6 CIRCUIT BREAKERIn M.O.C.B separating contact of the In SF6 separating contact of thebreakers are made to separate within breakers are made to separate withinan insulating oil. SF6 material.
    • ISOLATORS & ARRESTORS• Isolators are device which disconnect the instruments from power supply, the isolators provided at 220 KV switchyard are motor operated.• Lightening Arresters are used in switchyard for preventing from Lightening phenomena and are installed at entrance of switchyard.
    • CURRENT TRANSFORMER• Current transformers are provided for measuring and protection. All Current Transformers at 220 KV switchyard are BHEL manufactured .• Designed to provide a current in its secondary coil proportional to current flowing in its primary coil.• Primary winding consists of very few turns.• Secondary winding consists of large no. of turns• Current to be measured is passes through primary winding.
    • POTENTIAL TRANSFORMER• Used for the measurement of high voltages.• Primary winding is connected to voltage to be measured.• Voltmeter is connected across the secondary winding.
