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

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

Arduino Based Solar Cell Parameter Measurement System

Image
The project is  designed  to  measures different solar cell parameters like light intensity, voltage, current and temperature by using multiple sensor data acquisition. The project uses a solar panel to monitor sunlight and Arduino board which has ATmega family microcontroller attached to it. The project requires an LDR sensor for measuring light intensity, a voltage divider to measure voltage and a temperature sensor to measure the temperature. These measurements are then displayed by the microcontroller to a LCD screen. Thus this system allows user to effectively monitor solar parameters using this system.
