Abstract

There are several power generation units connected to the grid such as hydel, thermal, solar etc to supply power to the load. These generating units need to supply power according to the rules of the grid. These rules involve maintaining a voltage variation within limits and also the frequency. If any deviation from the acceptable limit of the grid it is compulsory that the same feeder should automatically get disconnected from the grid which by effect is termed as islanding. This prevents in large scale brown out or black out of the grid power. So it is preferable to have a system which can warn the grid in advance so that alternate arrangements are kept on standby to avoid complete grid failure. This paper is presented and designed to develop a system to forecasting before the synchronization failure and give alertness if any external supply source to the power grid on sensing the abnormalities in frequency and voltage.[1] This system is based on a microcontroller Arduino uno hardware and Matlab software. Arduino monitors the under/over voltage as well frequency being derived from a set of comparators. As the frequency of the mains supply cannot be changed, the project uses a function generator for changing the frequency, while a potentiometer is used to vary the input voltage to test the functioning of the project. A lamp load which indicates a predictable blackout, being driven from the Arduino in case of voltage/frequency going out of acceptable range. MATLAB can also support to make the database of all standard preset values.[2]
