Distribution, Switching & Control Assembly.
I completed this project as summer internship after my 4th Sem got finished.
I've used PIC 16F877a Microcontroller, and C as programming language. This project is presently being used in IPS (Integrated Power Supply) in Railways.
Hardware Description
1. Microcontroller – PIC 16F877A.
2. 16X2 LCD.
3. 4 Keys Keypad.
4. Serial to parallel IC
5. DAC
6. -12,+5 and +12 volts output SMPS
7. Operational Amplifiers.
Key Features
1. The system has 8 Analog input channels, through which it reads various voltages and currents, such as mains voltage, battery voltages, load current, etc.
2. It checks for a no of faults which can occur such as:
· AC Over voltage
· AC Under Voltage
· DC Over Voltage
· DC Under Voltage
· Battery Discharge and Depth of discharge
· System Overload
· Mains on battery Discharge
· Mains Current Overshoot
· Battery Current Overshoot
3. Displays the current status of :
· Mains Voltage
· Battery Voltage
· Battery current
· Total current
· Float/Boost status of battery.
· Mains Current
4. Separate setting for Users and Administrator, Factory Settings with Password Protection.
5. 23 settable options for both user and factory.
6. Separate warning tones for emergency warnings, such as emergency shut down, etc.
7. Trips off System automatically when overloads and Mains on battery discharge.
8. Automatic Compensations and regulations of currents, voltages and temperature.
9. Keeps track of battery’s charging automatically.
10. Features for types of battery used.
