Woodward 9907-029 SPM-A Synchroniseur

FAQ

1. What is the primary role of the 9907-029 SPM-A Synchroniseur?
It ensures safe and precise synchronization of generators to the grid or bus by matching phase, voltage, and frequency before connection.

2. How does the device detect phase or voltage mismatches?
It continuously measures incoming generator signals and compares them to the bus parameters, triggering alarms or control actions when mismatches occur.

3. What protections are included to prevent equipment damage?
It includes overvoltage, undervoltage, overfrequency, and phase mismatch detection to safeguard both the generator and the grid.

4. Can it operate automatically without manual intervention?
Yes. The SPM-A performs automatic synchronization once configured, reducing operator workload and minimizing human error.

5. How is synchronization status monitored?
Real-time voltage, frequency, and phase difference are displayed, often via LEDs or connected plant monitoring systems, allowing operators to verify readiness.

6. What should be checked if synchronization fails?
Inspect generator output, confirm correct connection of voltage and frequency signals, and ensure breaker and control interfaces are functional.

7. Is the synchronizer suitable for high-vibration environments like turbine rooms?
Yes. It is designed to withstand vibration and temperature ranges typical in industrial and power generation environments.

8. How is installation typically performed?
The unit is mounted in a control panel or rack, wired to generator outputs, bus connections, and optionally integrated with the plant control system.

9. Can it synchronize multiple types of generators?
Yes. It is compatible with various synchronous generators, provided the input voltage and frequency range fall within specification.

10. What maintenance is recommended for reliable long-term operation?
Regular inspection of wiring, verification of input signal integrity, and functional checks of LEDs and alarms ensure the synchronizer operates correctly over time.
