1. SCADA for Power Station Substation Monitoring
and Automation
This project designed using the Embedded system aids in
the measurement of Various Power station Parameters and
provides a serial interface to the PC.
The SCADA (Supervisory Control And Data
Acquisition System) is achieved by transferring the
parameters to a remote terminal and getting the feed back from
the remote computer and abide by the same.
This Project also supports Automatic Prediction and Self
Protection.
For Example, if a Transformer gets Over Heated, then
automatically the Loads will get Tripped Off.
The transfer rate of this system is 9600 Baud rate. This
enables us to view and track the online changes encountered in
the Particular parameter or of all the parameters. One of the
main advantage of this project is, it allows us to view all the
parameter readings simultaneously on the screen. The Graph
drawn on the screen keeps on tracking the changes on the
parameter. It also supports Background Processing of the
Parameters. The parameters are classified into Analog and
Logic Parameters
