SCADA Project – External Battery Management

📘 A academic example from the course Fundamentals of Safety-Critical Software in Power Systems. The project demonstrates a SCADA system for monitoring and controlling an external battery used for device charging, with charge/discharge simulation and command control via a dCom application.

⚙️ Configuration File (RtuCfg.txt)

The configuration file has been extended with the following parameters:

• A – scaling factor (default 1)
• B – offset (default 0)
• LowAlarm – lower capacity threshold (default 20)
• EguMax – maximum battery capacity (default 100)
• AbnormalValue – value for abnormal state (default = opposite of normal state)

👉 Normal states:

• T1, T2, T3, T4, I2 → OFF
• I1 → ON

🔄 Simulation Rules

1. If T1–T3 is active → capacity decreases by -1%/s.
2. If T4 is active → capacity decreases by -3%/s.
3. If I1 is active → capacity increases by +2%/s.
4. If I2 is active → capacity increases by +3%/s.
5. LowAlarm logic:
   • If K < LowAlarm → trigger alarm, deactivate T4 and activate I2.
6. EguMax logic:
   • If K = EguMax → deactivate the currently active charging source (I1 or I2).
7. The user may activate T1–T4 only if K > LowAlarm.
