AIM
To understand the necessity and to become familiar with
the modelling of power system and
components. And to apply different methods to analyse
power system for the purpose of system
planning and operation.
OBJECTIVES
i To model the power system under steady state operating
condition. To apply efficient numerical methods to solve the power flow
problem.
ii. To model and analyse the power systems under abnormal
(or) fault conditions.
iii. To model and analyse the transient behaviour of
power system when it is subjected to a fault.

algorithms for the formation of Y-Bus matrix and ZBus matrix.
UNIT II POWER FLOW ANALYSIS 9
Importance of power flow analysis in planning and operation
of power systems. Statement of power
flow problem - classification of buses into P-Q buses,

(algorithm and flow chart.).
UNIT V STABILITY ANALYSIS 9
Importance of stability analysis in power system planning
and operation - classification of power
system stability - angle and voltage stability – simple
treatment of angle stability into small-signal and
large-signal (transient) stability
