3. BACKGROUND
Transmission line is one the important compnent in
protection of electric power system because
the transmission line connects the power station with
load centers.
The fault includes storms, lightning, snow, damage to
insulation, short circuit fault [1].
Fault needs to be predicted earlier in order to be
prevented before it occur.
4. BACKGROUND
The fault must be detected early; hence the
possibility of disturbance with the transmission
can be reduced. It can be improved by
predicting early signs of the fault [2].
The signs of the fault can be made in the form
of algorithms in which algorithms are able to
specify the a parameters before fault occurs.
5. BACKGROUND
Alternative algorithms that can be used include
ANN, ACO, FUZZY LOGIC and PSO
This study will use Particle Swarm
Optimization (PSO).
This aims of this study are simulate the
occurrence of fault on the transmission line.
6. BACKGROUND
The types of fault that will be simulated are:
The single line to ground fault
The line to line fault
The double line to ground fault
Three phases of to ground fault
The lighting Strike fault
7. PROBLEM STATEMENT
The overhead transmission line , which often has varieties of
small or large disturbances is highly susceptible to interference
and it is necessary for fault detection.
Fault detection must be able to quickly determine the location
of interference as well as to classify type of fault quickly to
stabilize the electric power system .
Particle Swarm Optimization ( PSO) is able to detect
interference very quickly and with good accuracy. Hence it is
used in this study
8. OBJECTIVES

disturbance on the overhead transmission line by
using PSCAD / EMTDC software package
2. To develop mathematical model for various type of
disturbance on overhead transmission line.
3. To develop a smart algorithm for fault detection
using Particle Swarm Optimization (PSO).
9. SCOPE OF THE RESEARCH
1. Identification and simulation of various of
disturbance on overhead transmission line by
using PSCAD/EMTDC software. Version 4.2.0
2. Preparing suitable mathematical model for voltage
and current signals of the above disturbances.
3. Development of the proposed smart algorithm by
using Particle Swarm Optimization (PSO) method
in fault detection of overhead transmission line.
10. SIGNIFICANCE OF THE RESEARCH
1.The developed system aims to inform or warn the
operator that there is a possibility of fault occurs on
the transmission line. Then the operator can react to
the warning before the fault happens.
2.The numerical simulation program was developed
for fault detection will be based on PSO
optimization. Code optimization will be developed in
MATLAB, then the results of PSCAD-EMTDC will
be used in the MATLAB program
11. LITERATURE REVIEW

particle swarm optimization applications to power
system have seen found [3]

wavelet transform [4]

14. LITERATURE REVIEW
PSO has been widely applied in recent
transmission researches, such as , in the
reactive power control, the economic
dispatch, power system reliability, load
flow and electric machinery [3.33].
However there is a opportunity to study
fault detection in electric power
transmission systems using PSO.
15. LITERATURE REVIEW
New PSO method [21.34] does not use crossover and
mutation operators as in the GA [22] and this is the
advantage of this using method.
Other advantage of PSO method is a derivative-free
algorithm which is flexible and could be integrated
with other algorithms (GA, ANN, Fuzzy). Moreover, it
is easy to apply in mathematical model and does not
have the Initial Solution (23).
16. LITERATURE REVIEW
Fault detection on AC Induction Motor (35)
found that the PSO gives better result which is
above 90% compared with GA and also better
when compared to the PCA (Principle
Component Analysis).
The study of induction motor stator fault (7), it
is found that the application of the PSO based
method is more optimal and also improves the
detection speed.
17. LITERATURE REVIEW
Reactive power dispatch problem was
solved using the Particle Swarm
Optimization model for continuous
variables with discrete control variables
better than the main classical approach,

P-Q decomposition [36]
18. LITERATURE REVIEW
The state estimation problem was solved
using the Particle Swarm Optimization
based on the well known Weighted Least
Squares Estimation method approach
achieved a better estimation than an
iterative Newton method using a Mean
Square Error (MSE) analysis [36]
19. LITERATURE REVIEW
The unit commitment problem was solved using
the Particle Swarm Optimization model for
binary variables. The results were compared
with the results obtained from a Dynamic
Programming approach. The same global
solution was found showing the robustness of
the Particle Swarm Optimization model for
binary variables [36].
20. LITERATURE REVIEW

PSO has a derivative-free algorithms
PSO has the flexibility that is integrated with optimization techniques
to form hybrid device.
PSO less sensitive to the objective function, continuity and
convexity.
PSO has little parameter adjustments than other evolutionary
techniques.
PSO has a very easy application in mathematics and logic circuits
operating.
PSO can handle objective functions with a stochastic nature in the
case of one of the optimization as a random variable.
PSO does not require any initial solution to start the iteration
process.
