FAQ
1. What is the main function of the Woodward 9907-029 SPM-A Synchronizer?
The Woodward 9907-029 SPM-A Synchronizer automatically adjusts the speed of an offline generator so that its frequency and phase are matched with the bus before paralleling. The unit can also provide voltage matching and automatically issue a breaker-close signal when the synchronization conditions meet the configured limits.
2. What are the synchronization specifications of the 9907-029?
The 9907-029 is designed for 50/60 Hz applications with a selectable phase matching window. This specific model provides a ±10° phase-angle window and 1% voltage matching, allowing the generator voltage, frequency, and phase relationship to be brought within the required synchronization conditions.
3. What input voltage does the SPM-A 9907-029 require?
The synchronizer accepts 115 or 230 VAC RMS inputs from the bus and generator circuits, with a voltage tolerance of ±10%. Correct voltage selection and wiring are important because the unit measures the bus and generator voltage signals to determine their relative frequency and phase conditions.
4. What operating modes are available on the Woodward SPM-A Synchronizer?
The SPM-A provides RUN, CHECK, PERMISSIVE, and OFF operating modes. RUN permits normal synchronization and breaker closure, while CHECK allows synchronization and voltage matching without issuing a breaker-close signal. PERMISSIVE and OFF are used for controlled system operation and disabling synchronization functions as required by the installation.
5. How does the 9907-029 control generator speed during synchronization?
The SPM-A generates a speed-bias signal for the compatible governor or load-sharing control. It compares the generator and bus conditions and adjusts the prime mover speed so that generator frequency and phase approach the required synchronization window before breaker closure.
6. What is the purpose of the voltage matching function?
The voltage matching function adjusts the generator voltage toward the bus voltage before paralleling. For the 9907-029, the specified voltage matching capability is 1%. This helps reduce voltage differences between the generator and bus at the moment the circuit breaker is closed.
7. What should be checked if the 9907-029 does not issue a breaker-close signal?
Check that the unit is in the correct operating mode, the bus and generator voltage inputs are present and correctly wired, and the frequency and phase difference are within the configured synchronization window. The match-up time, permissive circuit, breaker circuit, relay wiring, and governor control output should also be checked. A CHECK-mode setting should be verified because this mode does not permit a breaker-close command.
8. Which control systems can be connected to the Woodward 9907-029?
The SPM-A provides selectable output configurations for Woodward 2301, 2301A, EPG, and 2500 load-sharing controls. It also supports EGA and EGM controls when the appropriate external resistor is used. The correct output type should be selected according to the governor or load-sharing control installed in the generator system.
