OVERVIEW POWERPLANT IN INDIA

The electricity sector in India had an installed capacity of 233.929 GW as ofDecember 2013, the world's fourth largest. Captive power plants generate an

additional 34.444 GW. Non Renewable Power Plants constitute 87.55% of the

installed capacity, and Renewable Power Plants constitute the remaining 12.45% of

total installed Capacity.

In terms of fuel, coal-fired plants account for 57% of India's installed electricity

capacity, compared to South Africa's 92%; China's 77%; and Australia's 76%. Aftercoal, renewable hydropower accounts for 19%, renewable energy for 12% and

natural gas for about 9%.

Oil supplies 30 % energy need in india

Some of the other prominent players in the oil power plant sector India are

Trombay power plants of Tata power, and Dahanu generation units of RelianceInfrastructure

Cost for setting up oil power plant is a small one is half a million a big one is 3

million and Power from diesel costs anywhere between Rs. 16-40/kWh, depending

on the application

Current installed base of Oil Based Thermal Power is 1,199.75 MW which is 0.57%

of total installed capacity.

ELECTRCITY GENERATION BY OIL

An oil power station turns the chemical energy in oil into electrical energy that can be used inhomes and businesses.

The oil is piped into the boiler where it is burned, converting its chemical energy into heat

energy. This heats water in pipes coiled around the boiler, turning it into steam. The hot

steam expands in the narrow pipes, so when it emerges it is under high pressure. The

pressure drives the steam over the blades of the steam turbine causing it to spin, converting

the heat energy released in the boiler into mechanical energy. A shaft connects the steam

turbine to the turbine generator so when the turbine spins, so does the generator. The

generator uses an electromagnetic field to convert this mechanical energy into electrical

energy.

The cold pipes cool the steam so that it condenses back into water. It is then piped back to

the boiler, where it can be heated up again, turn into steam again, and keep the turbine

turning. Finally, a transformer converts the electrical energy from the generator to a high

voltage. The national grid uses high voltages to transmit electricity efficiently through thepower lines to the homes and businesses that need it

Here, other transformers reduce the voltage back down to a usable level.As well as heat,

burning oil produces exhaust gases. These are piped from the boiler to the exhaust stack

which contains equipment that filters out any particles, before venting into the atmosphere.

The stack is built tall so that the exhaust gas plume can disperse before it touches the ground.

This ensures that it does not affect the quality of the air around the station.

TECHNOLOGIES USE IN OIL POWERPLANT

Three technologies are used to convert oil into electricity:

Conventional steam - Oil is burned to heat water to create steam togenerate electricity

Combustion turbine - Oil is burned under pressure to produce hotexhaust gases which spin a turbine to generate electricity.

Combined-cycle technology - Oil is first combusted in a combustion

turbine, using the heated exhaust gases to generate electricity. Afterthese exhaust gases are recovered, they heat water in a boiler,creating steam to drive a second turbine.

ADVANTAGES AND DISADVANTAGES OIL

POWER PLANTS

ADVANTAGES

The design and layout of the

plant are quite simple.

It occupies less space as the

number and size of the auxiliaries

is small.

It can be located at any place.

It can be started quickly and it

can pickup load in a short time. There are no standby losses.

It requires less quantity of water

for cooling.

It requires less operating staff.

DISADVANTAGES

The plant has high running

charges as the fuel (diesel) used is

costly.

Theplant doesnt work

satisfactorily under overload

conditions for a longer period.

The plant can only generate small

power.

The cost of lubrication is

generally high.

The maintenances charges are

generally high
