Transformer Load sharing system with SMS Altering
Power travels from the power plant to house through an amazing system called the power distribution grid. For power to be useful in a home or business, it comes off the transmission grid and is stepped-down to the distribution grid. This may happen in several phases. The place where the conversion from "transmission" to "distribution" occurs is in a power substation. It has transformers that step transmission voltages (in the tens or hundreds of thousands of volts range) down to distribution voltages (typically less than 10,000 volts). It has a "bus" that can split the distribution power off in multiple directions. It often has circuit breakers and switches so that the substation can be disconnected from the transmission grid or separate distribution lines can be disconnected from the substation when necessary.
The main aim of this project is transformers sharing whenever the load increased for certain value and also sending these changes information to the respective authority via SMS by using GSM modem. The transformer load sharing will be done by micro controller with the help of electro-magnetic relay. And the load will be monitored on LCD with help of current transformers.
A GSM (global system for mobile communication) modem is connected with the interfacing of the RS 232 (Recommended standard) protocol wireless data transmission. The controlling device of the whole project is a Microcontroller, GSM modem and LCD displays are interfaced to the Microcontroller. The micro controller will supervise all these devices.
The controlling device of the project is a Microcontroller to which input and output modules are interfaced. The Microcontroller is programmed using Embedded C language which provides effective environment for performing the task of the project. Express PCB software is extracted to design the circuit boards.
