Electrical Power System

Department of Electrical & Electronics Engineering, Amrita Vishwa Vidyapeetham, Coimbatore.

Power Systems

The function of Power Systems is to convert energy from

other forms to electricity and distribute it to the consumers.

Traditional Power Systems have three main components:

Generation

Transmission

Distribution (Load)

Department of Electrical & Electronics Engineering, Amrita Vishwa Vidyapeetham, Coimbatore.

Electrical Generation

Thermal (Coal, Gas, Diesel)

Nuclear

Hydro

Wind

Solar

Why AC and not DC ?

Break-even distance for HVDC

Department of Electrical & Electronics Engineering, Amrita Vishwa Vidyapeetham, Coimbatore.

Why a Sinusoidal Alternating Voltage ?

Department of Electrical & Electronics Engineering, Amrita Vishwa Vidyapeetham, Coimbatore.

The choice of Frequency

50 Hz or 60 Hz

Nowadays:

60 Hz in USA, Brazil and Japan (has also 50Hz)

50 Hz in most other countries

25 Hz Railways (North America)

16⅔ Hz Railways (Germany, Austria, Switzerland,

Sweden and Norway)

400 Hz Oil rigs, ships and airplanes

Department of Electrical & Electronics Engineering, Amrita Vishwa Vidyapeetham, Coimbatore.

The choice of Frequency

A too low frequency, like 10 or 20 Hz causes flicker

A too high frequency

Increases the hysteresis losses:

Increases the eddy current losses:

Increases the cable and line impedance
