Application Solutions
Power Generation: Manages steam turbine governors in combined-cycle plants, ensuring grid synchronization and load-following capability during peak demand cycles.
Oil & Gas Processing: Controls mechanical drive turbines for compressors and pumps in offshore platforms and refinery operations where reliability is mission-critical.
Industrial Cogeneration: Optimizes heat recovery steam turbines (HRST) in manufacturing facilities, balancing thermal and electrical output for maximum efficiency.
Key Benefits
Integrated overspeed protection with triple-redundant shutdown logic ensures safe operation even during sensor failures. The controller's self-diagnostic system continuously monitors valve position, speed deviation, and system health, alerting operators before minor issues escalate into costly downtime.
Common Questions Answered
Q: Is this compatible with legacy Woodward systems?
A: Yes, the 9905-864 offers backward compatibility with 505 series installations and can interface with older analog actuators through optional I/O modules.
Q: What's included in the warranty?
A: Every unit includes a comprehensive 12-month warranty covering manufacturing defects and component failures under normal operating conditions.
Q: Can it handle dual-fuel turbine applications?
A: Absolutely. The controller supports fuel switching logic and can manage gas/oil transitions without interrupting turbine operation.
