AN EFFICIENT MONITORING OF SUBSTATIONS USING MICROCONTROLLER BASED MONITORING SYSTEM
INTRODUCTION
Electricity is an extremely handy and useful form of energy. It plays an ever growing role in our modern industrialized society. The electrical power systems are highly non-linear extremely huge and complex networks . Such electric power systems are unified for economical benefits, increased reliability and operational advantages . They are one of the most significant elements of both national and global infrastructure, and when these systems collapse it leads to major direct and indirect impacts on the economy and national security .
RELATED WORKS
The process of rebuilding in the field of electricity industry results in a need of innovative techniques for representing a huge quantity of system data. Overbye and Weber [9] have presented a summary on various visualization techniques that might fairly be helpful for the representation of the data. The techniques such as: 1.) contouring, 2.) animation, 3.) data aggregation and, 4.) virtual environments must prove to be quite useful. Yet, important challenges remain. The major challenges are: 1.) the problem of visualizing not just the state of a existing system but also the potentially huge number of incident states, and, 2.) the problem of visualizing not just the impact of a solitary proposed power transfer but of a great number of such transactions.
MONITORING AND CONTROLLING BY THE PROPOSED SYSTEM
The values of voltage, current and temperature of the transformer is directly applied to Port A (one of the input ports of the AVR micro controller). Along with this, a display is connected in the Port B (another input port of the micro controller). The RF transmitting section and the load variation control are connected to the Port C (one of the output ports in the micro controller). The monitoring PC is connected to the main station.
