Detecting power grid synchronization failure on sensing out of range frequency or voltage

ABSTRACT
As the power grid failure problems continue to persist in the country, need arises to make it more efficient and effective. This is a demonstration devised to provide such kind of a system that could detect the failure in the synchronous working of the power grid in case any external supply source that is supplying to the grid is encountering any kind of abnormalities may be in current levels, voltage levels, temperature, and oil level. There are various generation units that usually supply power to the grids such as thermal plants, solar plants, hydro-electric plants etc. All the generation units that connect to the grid have to obey the rules or standards laid down for the operation of a grid.Automation in monitoring is very important part in industrial plants. This system can used to automate the electrical system where system is sensitive to voltage and change in frequency. It also serves for the safety in heavy industrial duty. Automation of cut off increases the reliability of the system.This project presents the development of a microcontroller based islanding detection for grid with over voltage and over frequency islanding detection algorithms. The system is based on a microcontroller from Atmel AVR family.
The microcontroller monitors the over voltage derived from a set of resistors and controller inbuilt ADC and over frequency from supply by the interrupt program using LCD for the utility grid and the processed value of voltage and frequency for turning ON/OFF the relay between a grid connected inverter and the utility grid. The microcontroller used in the project is of AVR family which is of 8 bit

Keywords: - Atmel AVR family, islanding, over frequency, over voltage

IoT Based Contact less Tachometer with Speed Control Using AVR Microcontroller and Hall Effect Sensor

Image
ABSTRACT Tachometer is device used to count the revolutions per minute of a rotating shaft. Generally tachometer makes direct contact with the rotating shaft. It will reduce the velocity of the shaft, giving faulty readings. Hence it is needed to measure the speed of rotating shaft without direct contact. This project describes a contact -less tachometer using AVR microcontroller ATmega328P and a hall affect sensor. This device can very accurately measure the rotational speed of a shaft without even touching it. This device is built on an ATmega328P microcontroller, an alpha-numeric LCD module and a Hall Effect sensor to detect the rotation of the shaft whose speed is being measured. In this project Hall Effect sensor acts as a digital counting device. It will detect any magnetic element passing in front of it and thus, will give an output pulse for each and every rotation of the shaft. These pulses are fed to microcontroller. Microcontroller counts the pulses coming from Ha...

Power Line Carrier Communication Using X10 Protocol

Image
ABSTRACT Most   electric   power   companies   employs   power   meter reader   to   collect   data   on   the customer’s energy consumption. Usually, this task is carried out manually, which can lead to high cost and errors, causing financial losses. This project has taken some approaches to minimize these problems. As in everywhere automation is required to reduce the work so we decided to implement to automatic meter reading using power line communication (PLC). Automatic meter reading (AMR) is the modern Power measuring device. It has advantages in safety, real time measuring and time saving as well as it has a better user interface and digital data analysis. Data is   send   over   existing   power   line   using   X10   protocol   that   reduces   the   complexity   and   cost   of system. In the latest generation of home automation systems, appl...
