The document discusses different aspects of electrical power generation systems in Malaysia. It begins with a brief history of electricity in Malaysia starting from 1894. It then discusses the national grid system which consists of generation, transmission, and distribution components. It also covers various energy sources used for conventional generation such as oil, coal, natural gas, and nuclear. Renewable energy sources like solar, hydro, and biomass are also mentioned. Different electrical power generation systems like steam turbines, gas turbines, and combustion engines are described. The principles and types of various power plants are provided.

4. 1.1 Introduction To Electricity In Malaysia
● 1894 Mr. Loke Yew & Thamboosamy Pillai installed an electric generator for their mining in
Rawang, Selangor.
● 1895 the railway stations in Kuala Lumpur received its first electricity supply.
● 1900 Raub Australian Gold Mining Company built the first power station in Malaya, the Sempam
Hydroelectric Power Station, in Raub town.
● 1 September 1949, the Central Electricity Board of the Federation of Malaya (CEB) was
established for the electrification of Peninsular Malaysia.
● 22 June 1965, CEB was renamed as National Electricity Board of the States of Malaya (NEB or
LLN)
● 1982, the NEB took over the Perak River Hydro Electric Power company (PRHEP) and its
subsidiary Kinta Electrical Distribution Co Ltd (KED). PRHEP which built the hydro-electric
station and dam at Chenderoh, was at one time the largest power supplier in Malaya

5. 1.1 Introduction To Electricity In Malaysia
● 1990 under the Electricity Supply Act, NEB was corporatized to become TNB.
● 1993 five companies were granted licenses to build, operate and own power plants in
Peninsular Malaysia. These so-called ‘First generation IPPs’.
● 1998, SESB was privatized and taken over by TNB as an 80% owned subsidiary.
● 2001, the government of Malaysia enacted the Five Fuel Policy in their 8th Malaysia
Plan.
● 2001 Energy commission Act enacted.
● 2009 National Green Policy was introduced

6. ● Is a Systems of generation, transmission and distribution of electricity
covering larger network across countries or continents.
● Ensures a continuous availability of sufficient energy supply for all
consumers, with adequate margin between supply and demand.
● Develops and maintains efficient, coordinated and economical
transmission system for bulk delivery of electrical energy.

9. 1.3 Energy Sources & Renewable Energy
Generation
CONVENTIONAL GENERATION
When we cannot reuse a source of
energy after using it once we call
them “conventional sources of
energy” or “non-renewable energy
resources”.

10. 1.3 Energy Sources & Renewable Energy Generation
OIL
The most common used in
electricity generation
PETROLEUM & NATURAL
GAS
Petroleum is the mixture
hydrocarbons like alkanes and
cycloalkanes
. Natural gas is a mixture of 50-90%
of Methane, Ethane, Propane,
Butane, and Hydrogen sulphide.
THERMAL PLANT
It is called as the thermal plant
because fuel is burnt to produce
heat energy which is converted
into electrical energy
Runs the turbine to generate
electricity
COAL
Coal is the most abundant
conventional source of energy
It is a black-brown sedimentary
rock
NUCLEAR
A small amount of radioactive
substance can produce a lot of
energy thr
ough the nuclear substances all
over the world.
Most environmentaly friendly

11. 1.3 Energy Sources & Renewable Energy Generation
RENEWABLE GENERATION
A renewable energy source means
energy that is sustainable - something
that can't run out, or is endless, like
the sun

15. 1.5 Operating Principle Of Steam Turbine
● Steams turbines are powered by hot, gaseous steam.
● Use high pressure steams to turn power generator at high
speed
● The operating principle is based on the dynamic motion
steam.
● It dissipate the energy of steam and turn it into kinetic
energy.
● The change of kinetic energy makes mechanical action
in the rotor blade, And this rotor has a connection with
the steams turbines generator.

16. 1.5 Operating Principal Of Steams Turbine

17. 1.6 Working Principle The Simple Gas Turbine Plant
● Air-fuel mixture ignites, creating a hot gas.
● Then, the hot gas spins the turbine.
● Spinning blade turn the drive shaft.
● Turbine rotation then powers the generator.
● Generator magnet causes electrons to move and creates electricity.

18. 1.6 Working Principle The Simple Gas Turbine Plant

19. 1.7 Types Of Gas Turbine Plant And Its Use
The gas turbine plants can be classified into two categories :
● Open cycle gas turbine power plant.
● Closed cycle gas turbine.

20. 1.7 Types Of Gas Turbine Plant And Its Use
Open cycle gas turbine
● In this type, ambient air is charged into combustor then
creating a heated gas. The heated gas then passed to the
turbine where it expands doing the mechanical works.
Then the heated gas released to the atmosphere.
● Normally used in electric power generation, aviation
power, and etc.

21. 1.7 Types Of Gas Turbine Plant And Its Use
Open cycle gas turbine working principle

22. 1.7 Types Of Gas Turbine Plant And Its Use
Closed cycle gas turbine
● In this type, air is circulated continuously within the gas
turbine. It performs thermodynamic cycle, which means
working fluid circulated and used continuously without
leaving the system.
● Normally used for wide range of energy sources such as
fossil fuel, concentrated solar power, nuclear, biomass and
waste heat.

24. 1.8 CONSTRUCTION TYPE COMBUSTION ENGINE
There are 2 types of combustion
engine:
Gasoline Engine
● The fuel is mixed and then
inducted into cylinder during the
intake process. After the piston
compresses the fuel-air mixture,
the spark ignites it, causing
combustion, The expansion of

25. 1.8 CONSTRUCTION TYPE COMBUSTION ENGINE
Diesel Engine
● In diesel engine, only air is
inducted into the engine
and then compressed.
Diesel engine then spray
the fuel into the hot
compressed at a suitable,
measured rate, causing it to
ignite.

Engines
