PLC-Based Parallel Operation Central Controller for Diesel Generator Sets in Data Centers

The PLC-based parallel operation central controller for diesel generator sets in data centers is an automated system designed to manage and control the parallel operation of multiple diesel generator sets, ensuring continuous and stable power supply during grid failures.

Key Functions

1. Automatic Parallel Operation Control:
   • Synchronization detection and adjustment
   • Automatic load sharing
   • Parallel connection/isolation logic control
2. System Monitoring:
   • Real-time monitoring of generator parameters (voltage, frequency, power, etc.)
   • Fault detection and alarm
   • Operation data logging and analysis
3. Load Management:
   • Automatic start/stop of generator sets based on load demand
   • Balanced load distribution
   • Priority control
4. Protection Functions:
   • Overload protection
   • Reverse power protection
   • Short-circuit protection
   • Other abnormal condition protections

System Components

1. PLC Controller: Core control unit for executing control algorithms
