INVESTIGATION LITERATURE

2.1 INTRODUCTION

To complete our project, investigation literature must be done to ensure the project done

successfully. Investigation include the problem faced the good and bad, and improvement of the

project.

Specifically for this project, an in-depth study on renewable power energy that the

present was done namely on its function to generate electricity.

2.2 POWER GENERATION SYSTEM IN MALAYSIA

Tenaga Nasional Berhad TNB! is the largestElectric utilitycompany inMalaysiaand

also the largest power company in Southeast Asia with MYR 69.8 billion worth of assets. tser!es o!er se!en million customers throughout"eninsular Malaysiaand also the eastern state

2.3 IMPORTANCE OF INVESTIGATION ( kenapa pen!n" n#a nk $e%!&!k 'en&e n!

Importance of research is to )now the different with the renewable power energy, its have so

many of different between the wind turbine system and the solar sytem.

Installing a wind turbine is a bit more involved than installing solar panels, but they are still

relatively easy to incorporate into our alternative energy system. The turbine needs to be

mounted in an area free from obstructions to wind flow nearby buildings, trees, etc.!.

*s a general rule however, the higher in the air you can get your wind turbine the more effective

it will be, so independent, guyed towers are the recommended mounting system. The wide

variety of available tower heights and styles ma)es it much more li)ely you will find a mounting

)it to suit your needs.

'hen installing the controls and wiring of a wind turbine system , it is important to understand

two fundamental differences between wind turbines and solar panels+

C))en Re*!+!e)$+ Solar panels produce direct current ! electricity reuired by power

storage batteries, and can be connected directly to the battery ban) without causing harm. 'ind

turbine system do not produce electricity, so a device called a /recitifier/ is used to convert

the turbine0s output current to . . In most cases though, the rectifier is supplied as a separate

component that must be installed between the wind turbine and the battery. 1ften, the rectifier is

combined with a charge controller into one complete wind turbine control unit.

L,a& D!-e)$!,n+ Solar panels are /passive/ electricity producers. 2ven though the sun is

shining, they only produce eletricity when a charge is needed by the battery. 'ind turbine

system are /active/ electricity producers. If the wind is blowing, they will produce current

whether the battery ban) needs the charge or not. In order to prevent damage to the wind turbine,

all of the electricity it produces must be /used/ in some way.

The renewable energy is one of the source stands out as an abundant, affordable and readily

available supply option+ wind power 5 solar.

'e found that the wind 5 solar power can supply #4 percent of electricity by #464 and reduce

projected emissions of carbon dio7ide 1#!, the leading greenhouse gas, by #8 percent. This

fact sheet is one in a series aimed at informing decision-ma)ers and the public about this

critically important option for the world energy future and countering persistent myths about the

renewable energy.

Sometimes wind opponents claim that because wind energy output varies with the wind speed,

wind turbine system reuire an euivalent amount of 9bac)up power: provided by solar system.

'e must understand why this myth is false reuires some e7planation of how the electric utility

system operates.
