Woodward 9905-708 DSLC Digital Synchronizer and Load Control
The Woodward 9905-708 delivers precision synchronization and intelligent load management for three-phase AC generators operating in parallel configurations. Engineered for mission-critical power generation facilities, this digital controller ensures seamless grid connection and optimal load distribution across multiple generator sets.
Technical Specifications
- Model Number: 9905-708
- Control Type: Digital Synchronizer and Load Control (DSLC)
- Voltage Range: 100-690 VAC, 3-phase
- Frequency: 50/60 Hz auto-sensing
- Load Sharing Accuracy: ±2% of rated load
- Synchronization Window: Adjustable ±5° to ±30°
- Operating Temperature: -40°C to +70°C
- Power Supply: 18-32 VDC or 88-132 VAC
- Communication: RS-485 Modbus RTU protocol
- Display: Multi-function LCD with status indicators
Key Applications
Industrial Power Plants: Coordinate multiple diesel or gas generators to maintain stable power output during peak demand cycles or grid outages.
Data Center Backup Systems: Ensure uninterrupted power by synchronizing standby generators with utility feeds and managing seamless transfer operations.
Marine Propulsion: Control shipboard generator sets for propulsion and auxiliary power distribution with precise load balancing.
Oil & Gas Facilities: Manage remote power generation systems in offshore platforms and pipeline compression stations where reliability is non-negotiable.
Advanced Control Solutions
The 9905-708 employs microprocessor-based algorithms to monitor voltage magnitude, phase angle, and frequency differential between incoming generator and bus systems. When synchronization parameters fall within preset tolerances, the controller issues a close command to the generator breaker, achieving smooth paralleling without mechanical stress or electrical transients.
Active load sharing distributes kW and kVAR demand proportionally across paralleled units based on droop characteristics or isochronous control modes. Real-time adjustment compensates for fuel quality variations, ambient conditions, and aging equipment to maintain balanced operation.
Common Questions
Q: Can the 9905-708 synchronize generators with different ratings?
A: Yes, the controller supports mixed-capacity generator sets. Load sharing is proportional to each unit's rated output, ensuring no single generator is overloaded.
Q: What happens if communication is lost during parallel operation?
A: The module includes fail-safe logic that maintains last known load setpoints and can operate in standalone mode until communication is restored.
Q: Is this compatible with renewable energy integration?
A: The 9905-708 can coordinate with solar inverters and wind turbines when configured with appropriate interface modules for hybrid power systems.
Q: How do I update control parameters?
A: Configuration is performed via front-panel keypad or through Modbus communication using Woodward's GAP software suite for remote programming.
Warranty & Support
Every Woodward 9905-708 module includes a comprehensive 12-month manufacturer warranty covering defects in materials and workmanship. Technical support includes installation guidance, parameter optimization, and troubleshooting assistance from certified engineers.
