Module 1: INTRODUCTION
This module contains a general description of electric
power systems. Definition of a power system, basic
characteristics, structure of modern power systems,
and problems in power system operation are then
identified. The performance requirements of properly
designed power systems are also described.

Module 2: BASIC CONCEPTS
This module contains basic concepts required
in analyzing a power system : single phase
network in a steady-state condition with a
sinusoidal input, electric power in a single
phase network (sinusoidal form and complex
form), power flow, symmetrical three phase
network, voltage, current and power in a three
phase network. Ontoseno Penangsang
Module 3: SYSTEM MODELING
This module contains single phase equivalents of main
components of a power system : synchronous
generator, transmission line, transformer, load; Power
system representation : single line diagram (single
phase), single phase impedance diagram and
admittance diagram, calculation in a power system
using per unit system; and Formation of bus admittance
matrix (Ybus) and bus impedance matrix (Zbus).

Ontoseno Penangsang
Every power system has three major
components
– generation: source of power, ideally with a
specified voltage and frequency
– load: consumes power; ideally with a
constant resistive value
– transmission system: transmits power;
ideally as a perfect conductor
Ontoseno Penangsang
No ideal voltage sources exist
Loads are seldom constant
Transmission system has resistance,
inductance, capacitance and flow
limitations
Simple system has no redundancy so
power system will not work if any
component fails

Basic Components of Electric Power:
How electricity gets to youHow electricity gets to you
When electricity leaves a power
plant (1), its voltage is increased
at a “step-up” substation (2).
Next, the energy travels along a
transmission line to the area
where the power is needed (3).
Once there, the voltage is
decreased, or “stepped-down,”
at another substation (4), and a
distribution power line (5) carr ies
the electricity until it reaches a
home or business (6).
