Power System
1.2 The Sources of Electrical Energy (Pg 18)
1.1 Introduction to Power System (Pg 2)
Electrical Power System / Electric Grid (Pg 2)
2) Transmission
Large factory, building
The areas enclosed by red borders indicate the introductory range of amorphous core transformers. (22000 V or less)
3) Distribution
Medium factory, building
1) Generation
Thermal power
Atomic power
Wind power
and soon...
4) Customer
Small factory, Store, Standard home
Law of conservation of energy (Pg 6)
Energy can neither be created nor destroyed
Only converted from one form of energy to another
Useful output energy is always lower than input energy
Losses in electrical power system (Pg 7)
Electricity Generation (Pg 9)
Process of generating electric power from sources of primary source
The facility for electricity is know as...
Power station
Generating plant
Power plant
Generating station
Generator
A device that convert mechanical energy into electrical energy
Transmission Line (Pg 14)
definition
Transfer electric energy from generating units at various locations to the distribution system
Sub-transmission connects the HV substation through step-down transformers to the distribution substation
Capacitor banks/ reactor banks are used to maintain the transmission line voltage
Transformers
Distribution System (Pg 16)
The secondary distribution lines are normally at 400 V and 230 V
Distribution systems are both overhead and underground
The primary distribution lines are ranging from 6.6 kV to 33 kV
Electrical Loads (Pg 17)
Commercial load
lighting, heating, and cooling
Residential load
Industrial load
Very large industrial loads may be served from the transmission system
Mostly induction motors
Greatest value of load during a 24-hr period is called peak or maximum demand.
