Description
The 9905-003 is a SPM-A Synchronizer part of the WoodWard SPM-A synchronizer series family. These synchronizer modules are designed with a series of user-adjustable dynamics to match those of the engine. The 9905-003 operates by biasing the speed of the offline generator it is attached to, to allow the frequency and phase to match those of another generator in the system. After that, it issues a contact closure signal to close the circuit breaker when they’re matched within the limits before the specified time of match-up.
Applications
Power Plants: Automatically regulate generator frequency and phase for grid synchronization.
Substations: Manage multi-source power transfer and phase synchronization for grid interconnection.
Hydroelectric Power Plants: Control turbine-generator speed and match system voltage requirements.
Thermal Power Plants: Ensure precise synchronization and breaker closing between turbine generators and the main grid.
Internal Combustion Engine Power Plants: Coordinate the parallel operation of multiple diesel or gas generator sets.
Key Features
Debugging and Configuration: Password-protected front panel settings and PC connection via the rear serial port for parameter copying and offline programming.
Engine Management: Supports diesel engine start/stop control, pre-glow operation, and D+ generator fault monitoring.
Control and Switch Combinations: Supports single or dual circuit breaker control with built-in interlocks, eliminating the need for external intermediate relays.
Troubleshooting and Handling
Switch tripping or current surge during grid connection: Usually caused by phase or voltage mismatch. Check 5% voltage matching and ensure phase angle stays within ±10°. Adjust output gain if actuator lag occurs.
Slow synchronization or no breaker closure: Verify stable speed sensor input. EMI from nearby drives may distort frequency signals, preventing locking and closing pulse output.
Unable to read status via debugging software: Check RS-232 wiring. In harsh environments, ensure IP65 seals are intact to prevent moisture or dust affecting communication contacts.
