The present thesis, Microcontroller Based Power Theft Identifier, introduces the concept of preventing the illegal usage of the electrical power.
Here, the radio communication principles are employed and also the technology of Microcontrollers is utilized to find out the user trying for pilferage of power i.e., by displaying the respective consumer meter number and address.
For the complete operation, the system can be sub-divided into two major sections, one is the transmitting section and the other is the receiving section.
The transmitting section has to be incorporated at the consumer’s end and the receiver section has to be placed at the electrical sub-station.
In the transmitting section, two types of automatic power theft detection schemes are provided. In the first scheme, within the meter (inside the bottom cover), an electro-optical sensor is placed and it is configured to feed trigger signal for the timer circuit.
WHAT DOES OUR PROJECT DO ?
The proposed project work aims on the design and development of energy theft prevention aspect.
Thereby, energy pilferage can be reduced to a considerable extent. This project envisages the development of energy theft identification. Hence this project work is titled as “MICROCONTROLLER BASED POWER THEFT IDENTIFIER”.
As we know the modern communication plays a dominant role in the communication revolution, the proposed project work is aimed to use radio communication between energy consumer and centralized electric sub-station, where the energy theft monitoring is performed.
Hence we have divided into two unit’s i.e.
(1) energy theft detection at energy consumer’s place, (2) Centralized radio receiver, where the power theft information is received, decoded and monitored using Microcontroller
In this project work, for the demonstration purpose two analog energy meters are considered, one is equipped with light sensing circuit and the other one is equipped with touch sensitive circuit
The system consumes very little power for its operation.
System operation is independent of time (24 hours functioning).
Automatic user identification.
Since the techniques employed in this module are based on simple electronics, the chances of making the system inoperative are more. But, if a Microcontroller chip is used for feeding the modulating input, we can make the system more efficient.
Wide range of frequencies is required to facilitate large number of users. To overcome this, carrier levels can be changed from region to region.
Presently, it requires a power supply (230 V) for the operation, but a small battery with automatic charging facility can be provided in real time.
The system can be incorporated for almost all types of users.
The concept is well suited especially for villages and interior areas.
