BDPP , a public sector agency under the

Government of Kerala, that generates and

distributes the electricity supply in the state.

The plant is controlled by Kerala load

Distribution Center(KLDC)

KLDC decides whether to produce or to buy

power(whichever profitable)

Brahmapuram Diesel Power Plant

Capacity : (106.6 MW)

Efficiency of the plant :38%

Fuel used :Diesel (for starting)

: LSHS(low sulphur heavy stock )a bye product of crude oil distillation,

provided by IOC

MECHANICAL DIVISION

The plant works on diesel engine.MAN DIESEL

A provider of large-bore diesel engines for powerplant applications

4 stroke diesel engine is used.

Number of Cylinder : 18

Type of Cylinder : V type

Engine capacity : 18000 cc/cylinder

Engine power : 30,000 bhp


5/17

LSHS is in semisolid form, it is heated by steam

to make it liquid form.

When melts it becomes the same form of

diesel.

The transfer of diesel to LSHS is done by a

three valve mechanism(first diesel, then a

mixture of diesel and LSHS, then LSHS)

MAINTENANCE DIVISION

There are totally five units of machines which

are similar.

Either two or three will be in work and the

others remain idle.

Once any problem occurs to the working unit,

it is shut downed and the idle unit is operated


10/17

Most common problems which require

maintenance

Corrosion of piston.

Bending of crank

Burning of piston ring

All the above problems mainly occur due to the

idleness of machine


11/17

Other maintenance

Lubrication and oil change.

Changing of burned piston rings.

Cleaning of cylinder valves.

Maintenance of turbo charger


14/17

Electrical Division

The engine is coupled with an alternator.

The alternator consists of a stator and a rotor.

The entire assembly is under one case.


15/17

Switch gears of 220kv, 25000 A are used to

control the supply.

Then the load is reduced to 11kv for

transmission, with the help of step down

transformers


16/17

It uses direct current for all its applications

(easy to store )
