prevention of power theft and power uality by the help of fuzzy logic

  1. 1. A SEMINAR PRESENTATION ON “POWER THEFT PREVENTION AND POWER QUALITY IMPROVEMENT USING FUZZY LOGIC” Submitted to: Submitted by: Mr. Ankush Tandon Vaibhav Bindal Mrs. Deepti Arela (10ESKEE122) 1

  3. 3. INTRODUCTION  The electricity sector in India had an installed capacity of 237.742 GW as of February 2014, the world's fourth largest.  India's network losses exceeded 35% including non-technical losses out of which technical losses is estimated to be 22.65% in 2013. compared to world average of less than 15%.  One of the important mischief is the power theft which is contributing a larger amount to the nontechnical losses in transmission and distribution. 3
  4. 4.  Aim of the paper is to reduce power theft and improve the power quality by the the help of Fuzzy logic . 4
  5. 5. POWER THEFT  Power theft could be defined as using the electricity without paying for it basically it is stealing of electricity.  Two kinds of theft are prevalent in power systems. 1) The Meter tampering 2) The direct rigging of the distribution line 5
  6. 6. THE METER TAMPERING  Meter tampering is the method of tampering the meter by removing it’s seal .  By-passing the meter so that a lower reading of power use.  Standard electro-mechanical meters use a slowly spinning disk to record the amount of power that is being drawn , the disks can be slowed using magnets . 6
  7. 7. 7 PREVENTION:-  the prevention of power theft of this type can be detected by placing a LDR circuit inside the meter .
  8. 8. THE DIRECT RIGGING OF THE DISTRIBUTION LINE  The most visible indication of energy theft occurs when users illegally tap into the public supply.  we cannot identify the power theft automatically. 8
  9. 9. POWER QUALITY  The quality of electrical power may be described as a set of values of parameters such as  continuity of service,  variation in voltage magnitude,  transient voltages and currents  harmonic content in the waveforms.  power quality is a convenient term for many, it is the quality of voltage which is supplied to the consumers rather than current or power. 9
  10. 10. FUZZY LOGIC  Fuzzy logic can be conceptualized as a generalization of classical logic.  There are not just two alternatives but a whole continuum of truth values for logical propositions. 10

  14. 14. EXAMPLES OF MATLAB RESULTS 14  Result of Over-Voltage : If the voltage is 151V then the change voltage is -151V
  15. 15.  Result of Normal functioning: If the voltage is 230V then the change voltage is 0V. 15
  16. 16. RESULT OF POWER THEFT: VOLTAGE IS BROUGHT DOWN BELOW THE CRITICAL VALUE IN CASE OF POWER THEFT. 16
  17. 17. CONCLUSION  Thus , the application of intelligent control in electrical system can improve the power quality and at the same time prevent illegal activities . The power theft prevention would be a boom to a country’s economy in managing the need for power generation. 17
