This document discusses applications of artificial intelligence technologies like expert systems to power systems. It notes that AI, in the form of expert systems, artificial neural networks, and fuzzy logic, can help address challenges in power system analysis due to large, complex data and computational requirements. Some key applications of AI in power systems mentioned include fault diagnosis in transmission lines, control of power systems and FACTS devices, and mobile robotics for remote monitoring and maintenance of power plants. The advantages of each AI technique for power systems are also summarized.

3. ABSTRACT :
 Application of Artificial Intelligence technologies (mainly in the form of
Expert Systems) to power systems has been an active area of
research for about a decade and significant successes have been
achieved. This paper lists the literature related to artificial intelligence
applications to power systems and notes the artificial intelligence
technologies that are becoming important in conjunction with expert
systems.

4. Power system
1.an electrical power system is a network of electrical
components used to supply, transmit and use to electric power.
2.Power system engineering is a subdivision of electrical
engineering deals with the generation, transmission, distribution
and utilization of electrical power and the electrical devices
connected to such systems like generartor, motors, and
transformers

5. ARTIFICIAL INTELLIGENCE
 AI is a branch of a computer science that is concerned with
the automation of intelligent behavior
 In other words AI is the science of automating intelligent
behaviours currently achivable by humans only
 Commonly artificial intelligence is known to be the
intelligence exhibited by machines and softwares.
 For example robots and computer programs

6. NEED FOR AI IN POWER SYSTEMS
 Power systems analysis by conventional techniques
becomes more difficult because of :
 1.complex,versatile and large amount of information which is
used in calculation , diagnosis and learning.
 2.increase in the computational time period and accuracy
due to extensive and vast system data handling.

7. AI TECHNIQUES
 There are three major families of AI techniques are
considered to be applied in modern power system protection
1. expert system techniques (XPSs)
2.artificial neural networks (ANNs)
3.fuzzy logic systems (FL)

8. EXPERT SYSTEM
 An expert systems are
computer programs which have
proficiency and competence in
particular field
 Expert system use the interface
mechanism and knowledge to
solve problems which is cannot
be or difficult to solve by human
skill inteligence

9. ARTIFICIAL NEURAL NETWORKS
artificial neural networks are biologically inspired systems
which convert a set of inputs into a set of outputs by a network
of neurons, where each neuron produces a one output as a
function of input.
Anns are classified by their architecture ,number of layers and
topology, connectivity pattern, feed forward or recurrent

10. ARTIFICIAL NEURAL NETWORK

11. FUZZY LOGIC
 Fuzzy logic or fuzzy systems are logical systems for
standardization and formulation of approximate reasoning.
 Fuzzification provides superior expressive power, higher
generality and an improved capability to model complex
problems at low or moderate solution cost.

12. FUZZY LOGIC

13. ADVANTAGES
EXPERT SYSTEM
1.it is permanent and
consistent
2.it can easily
documented
3.it can easily
transferred and
reproduce
Ann
1.speed of processing
2.they are fault
tolerant
3.anns are fast and
roubust
FUZZY LOGICS
1.power system
control
2.fault diagnosis
3.security
assessment
4.load forecasting

14. PRACTICAL APPLICATION OF AI IN
TRANSMISSION LINE
 In any fault occurs in the transmission line ,the fault detector
detects the fault and feeds to the fuzzy system. Only three
line currents are required to implement this technique and the
angular difference between the fault and pre fault current
phasors are used as input to the fuzzy system.these are
generally used for fault diagnosis
 Ann and XPSs can used to improve the performance of the
line

TRANSMISSION LINE

16. CURRENT APPLICATIONS OF AI IN
POWER SYSTEMS
 Operation of power systems
 Planning of power systems
 Control of power systems
 Control of network like location, size and control of facts
devices
 Electric markets
 Automation of power systems

17. PRACTICAL APPLICATIONS OF AI IN

18. MOBILE MONTERING SYSTEM OF
POWER PLANTS
 It means controlling of power system by various automated
means from sate distance .
 The developments in robotic maintenance for power system
indicates significant potential of this technological approach.
 It includes various sensors like : firing field sensing , infrared
sensing

19. LINE SCOUT ROBOT
 The three-axis robotic arm has been
designed to reach the four conductors
of a transmission line ,one end of the
arm is equipped with a point able
camera and other can hold a variety
of tools for task such as :
 High quality visual inspection
 Temporary repair

20. SNAKE ARM ROBOT
 Snake arm robot aims to reach
the unreachable.
