Electrical Station Variables Reader/Controller With True Graph And SCADA

This project “Electrical Station Variable Reader/Controller with True Graph” designed using the PIC Micro controller 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 feedback from the remote computer and abide by the same.

This Project also supports Automatic Prediction and Self Protection.
For eg if a Transformer gets Over Heated, then automatically the Loads will get Tripped Off.

The transfer rate of this micro controller is 19400 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

Analog Parameters:

1. Incoming Voltage
2. Bus Voltage
3. 3 - Feeder Current
4. Max Bus Current
5. Incoming Current
6. Power
7. Active Power
8. Power Factor
9. Frequency

Logic Parameter:

1. Over Heat Protection
2. Flame Identification
3. Trespassing Identification

Software:

Software Compatibility with ‘C’ and Visual Basic.
