Description
The Woodward 9907-029 is a SPM-A Synchronizer used to automatically match generator frequency and phase before paralleling with other power systems. It is commonly used with Woodward 2301, 2301A, and Electrically Powered Governor (EPG) load sharing control systems to ensure stable and precise grid connection.
Applications
Power Plants: Control generator voltage, frequency, and phase for fast grid synchronization.
Diesel Power Plants: Manage multi-unit speed bias and parallel operation.
Thermal Power Plants: Control turbine speed and phase to reduce breaker closing impact.
Petrochemical Plants: Coordinate gas turbine generator networks for compressors.
Substations: Control synchronization for multi-source power switching.
Troubleshooting
Voltage Sync Timeout: Verify that the incoming high voltage is within the 115 to 230 V AC range and check if the 1 percent voltage matching threshold requires manual governor bias adjustments.
Phase Breaker Not Closing: Inspect the phase angle limit loop; ensure the generator frequency is close enough to the bus frequency to let the module pull the phase angle within plus or minus 10 degrees.
