INTRODUCTION

KSTPS is first coal based power plant in Rajasthan.

It is located ideally on the left bank of CHAMBAL

River at the upstream of KOTA BARRAGE.

Its first unit of capacity 110 MW is commisioned on 17

jan 1983 and last one on 2009.

It is one of highest power generating plant with

installed capacity of 1240 MW.

PLANT OVERVIEW

COAL HANDLING PLANT

• 20000 tons coal requirment per day.• The main coal sources are:

1. Coal India Ltd. (CIL)

2. South Estern Coalfield Ltd. (SECL)

3. Northern Coalfield Ltd. (NCL)

(coal comes from 1000 km distance)

• Everyday 3- 4 trains of coal are unloaded, each train consists 58 wagons.(approx 3500-3800 tons)

• Coal is unloaded from wagons by means of WAGON TRIPPLER

• Stock yard Capacity -5.0 lack tons• Secondary fuel :-oil (HSD/ LDO)

Main parts of Switchyard

• CIRCUIT BREAKER

• ISOLATOR

• CURRENT TRANSFORMER

• POTENTIAL TRANSFORMER

• LIGHTNING ARRESTOR

TYPES OF CIRCUITS BREAKER

MINIMUM OIL CIRCUIT BREAKER SF6 CIRCUIT BREAKER

In M.O.C.B separating contact of the breakers are made to separate within an insulating oil.

In SF6 separating contact of the breakers are made to separate within 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.
