Grid Frequency Controller using Microcontroller 89V51.

Abstract

This paper contains the problems related with frequency. It is one of the effective tools to maintain the reliability by controlling the grid frequency of the power system. The Grid frequency controller is used with microcontroller for individual load shedding purpose. Because of this, the nearby areas can not be affected. As the demand of electricity increases; at the generating stations there will be increase in the load and hence the decrease in the generating frequency can occur .To maintain the frequency in the decided range i.e. 49 to 51Hz lot of additional resources like coil, water etc are being used currently. If this goes out of control then MSEB will switch off the supply to the Grid and thus the Load Shading for whole area occurs commonly. Therefore no one will be able to have the electricity until the load demand reaches to its nominal value. By the time in generating stations the generation of electricity will not stop and it is only wastage. To avoid this lot of work is going on .Our present concept is a part of that. Its approach is at individuals instead of some particular area. Keywords: Grid frequency; Microcontrol
