INTRODUCTION

For the power generation with 2x110 MW and 3x210 MW of K.T.P.S. authorities are

required to be operative to active full operation. The auxiliaries are basically operation either

on L.T. System i.e. 415 V 3 ? power supply is made available to the system after providing

the station transformer of 3x50 MVA capacity with voltage 220 KV/ 7.2/7.2 KV & differentservice transformers of capacity 1.0 MVA , 1.5 MVA , 2.0 MVA , which are located near the

load centre as the transformer having the voltage of 6.6 KV /415 V. The 6.6 KV power is

distributed through 6.6 KV interconnected Bus System for all the five units with a control

through DC of 220 V.

The 415 V power supply is done through a L.T. SWGR (Switchgear) which are located

nearby the distribution transformer as well as the load centers. The all in -comers, which are

breaker controlled , are having the control the L.T. SWGR are having the control system on

110/ 220 V AC. The 6.6 KV power supply which are either MOCB (Minimum Oil Circuit

Breaker) of JYOTI MAKE or Air Circuit Breakers.

The 6.6 KV power supply to various draining equipment?s i.e. more is made through

breakers which are either MOCB of Jyoti make air circuit breaker which are either of voltage

makers as well as SF 6 of NGEF make. The LT supply is also controlled through air break

circuit breaker which are either L&T make or English Electric Company of India. The

various H.T. motors are switched on / started through on direct ON line (DOL) in order to

inverse the availability of equipment at full efficiency without time gap.

Further , the 6.6 KV system which is normally in delta configuration and terms as anunearthed system so also to keep the running motor complete in operating condition in case

of any one .phase of motor winding is earthed due to any one reason. Earthling is detected by

an protection system with alarm facility to take remedial measures immediately and at thesame time to maintain the generation level in the same condition, prior to occurring the earthfault the single phase earth fault is detected in due course till the motor is not earthed to other

or another phase.

? PUBLIC ADDRESS SYSTEM? is available through in area of each unit which helps in fast

communication for prompt remedial measure.

Soot Blowers are there in the boiler area on the furnace side or Zone which helps in blowing

the soot / ash deposition regularly of the furnace wall / economizer tubes to keep heat transfer

at the required parameter.

In April 1973, Central Electricity Authority prepared a Project Report for power station

comprising of the two units of each of capacity 110 MW for RSEB subsequently inSeptember., 1975 this was revised by the Consultant Thermal Design Organization , Central

Electricity Authority for invention of 2x110 MW units being manufactured by BHEL,

Hyderabad in 1st Stage.

The planning commission cleared the project report in Sept., 1976 for installation of two units

each of 110 MW in first estimated cost of Rs. 143 Crores.

K.T.P.S. IS DESISIGNED IN FOUR STAGES

I - 2x110 MWSTAGE II - 2X210 MW

STAGE III - 1X210 MWSTAGE IV - 1X195 MW *

Total Power Generation - 1045 MW* To be commissioned shortly in August, 2003.

LOCATION

The Kota Thermal Power Station is ideally on the left bank of Chambal River at Up Stream

of Kota Barrage . The large expanse of water reached by the barrage provides an efficient

direct circulation of cooling system for the power station. The 220 KV GSS is within ? Kms.

from the power station.

LAND

Land measuring approx. 250 hectares was required for the project in 1976, For disposal of

ash tank very near to power station is acquired which the ash in slurry form is disposed off

through ash and slurry disposal plants.

COAL

Coal India limited owns and operates all the major coal fields in India through its coal

producing subsidiary companies viz. Eastern Coal Fields Limited, Western Coal FieldsLimited/

Coal India limited is supply coal from its coal mines of coal producing subsidiaries BCCL,SECL & ECL to Kota Thermal Power Station through railway wagons. The average distances

of SECL, ECL & BCCL are 800, 950 and 1350 Kms. respectively.
