Grid frequency based load control using pic microcontroller

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 PIC 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. If this goes out of control then MTPS will switch off the supply to the Grid and thus the Load shedding will be avoided for the total area.
