Functional Description

5448-906 is a Control SPM-D10 developed by Woodward. The SPM-D10 is a microprocessor-based synchronizer specifically designed for three-phase AC generators. It is compatible with Woodward speed controls and automatic voltage regulators, as well as other compatible systems. The primary purpose of the SPM-D10 synchronizer is to facilitate the automatic matching of frequency, phase, and voltage during the synchronization process. When synchronizing generators, it is crucial to ensure that the incoming generator is properly synchronized with the grid or other connected generators. The SPM-D10 synchronizer employs advanced technology and algorithms to automatically adjust the generator's frequency, phase, and voltage to match the desired parameters. This ensures smooth and seamless synchronization, minimizing the risk of voltage or frequency disturbances.


  • The SPM-D10 synchronizer offers the flexibility of utilizing either analog or discrete output bias signals for frequency, phase, and voltage matching. Analog output bias signals provide a continuous range of adjustments, while discrete output bias signals allow for incremental adjustments. This flexibility allows the synchronizer to adapt to different control systems and generator configurations.
  • As a microprocessor-based device, the SPM-D10 synchronizer benefits from the computational power and intelligence of a dedicated processor. It can perform complex calculations and monitoring functions in real-time, ensuring accurate and precise synchronization. The microprocessor also enables the synchronizer to incorporate advanced features such as fault detection, diagnostics, and self-adjustment capabilities.
  • By using the SPM-D10 synchronizer, operators can automate and streamline the synchronization process, reducing the risk of human error and enhancing overall system reliability. The synchronizer continuously monitors and adjusts the generator's output to maintain optimal synchronization, even in dynamic conditions or during load changes.
  • SPM ensuries accurate synchronization of multiple power sources, such as generators or other power generation equipment. It facilitates the coordination of these sources, enabling them to operate in harmony and provide a stable and reliable power supply.
  • The module incorporates advanced algorithms and control logic to accurately detect and adjust the voltage, frequency, and phase relationships of multiple power sources. It ensures proper synchronization and avoids potential issues such as phase mismatches or voltage imbalances. This component include a user-friendly interface, allowing operators or engineers to monitor and configure the synchronization parameters according to specific requirements. It provides real-time information and feedback on the status of the power sources and synchronization process, enabling efficient monitoring and control.

System Features

  • MicroNet TMR systems are designed to operate at 3-2-0. As a result, in order to start a system, at least two CPUs must be started with the same application. If the CPUs are started individually, the first CPU will wait indefinitely for the second CPU, and the second and third CPUs will wait up to ten seconds for the third CPU. If the third CPU does not join the two within 10 seconds, the two CPUs will continue with only two.
  • To synchronize, CPUs that start at the same time must use the same application and have the same EE values (stored tunables). If two CPUs are synchronized, a third CPU must run the same application as the first two, but it will copy EE values from the running CPUs. The TMR5200 and Remote RTN modules can be inserted and removed live in a MicroNet TMR or Plus chassis. Before removing these modules from the chassis, they must be reset. This informs the module that it will be removed and, if available, provides a graceful CPU shutdown or failover to another healthy Remote RTN module.

  • Enhanced Display and Visualization: Equipped with a two-line liquid crystal text display, the module provides a clear interface for operation, alarm indication, and the visualization of measurement values. This visual feedback empowers operators to make informed decisions and quickly identify any potential issues.
  • Synchronoscope with LEDs: The presence of a synchronoscope with LEDs enhances visual monitoring and assessment of synchronization status, contributing to smooth and precise synchronization processes.
  • Multiple Power Supply Options: The module offers a variety of power supply options, catering to diverse power infrastructure requirements. This adaptability ensures seamless integration into different systems.
  • Configurability for User Convenience: Both PC and front panel configurability options are available, enabling users to tailor the module's settings to their specific needs and preferences. This customization enhances ease of use and aligns the module's performance with operational requirements.

Versatile Application in Diverse Settings

  • The SPM-D2-10 synchronizers are purpose-built for three-phase AC generators, and they seamlessly interface with Woodward or compatible speed controls and automatic voltage regulators.
  • These synchronizers excel at automatic frequency, phase, and voltage matching, thanks to their ability to utilize both analog and discrete output bias signals. This versatility makes them a valuable addition to a wide range of prime movers and generators.
  • Whether it's fast-reacting diesel engines or soft-reacting gas turbines, these synchronizers adapt to the unique control signals required for optimal performance.

Security and Configuration Flexibility

  • Security is paramount in today's interconnected world. That's why all SPM-D2 synchronizers come with password protection, ensuring the integrity and safety of your power generation systems. Configurability is also a key aspect of the SPM-D2 series.
  • Set your parameters either through a user-friendly HMI interface, as with the previous SPM-D units, or through the ToolKit configuration tool, which offers USB connectivity for ease of use.

Frequently Asked Questions

What is 5448-906?
It is a Field Terminal Module developed by Woodward.

What is the minimum number of CPUs required to start a MicroNet TMR system?
To start a MicroNet TMR system, at least two CPUs must be started with the same application. This configuration ensures the system operates in a 3-2-0 setup, which provides redundancy and fault tolerance.

What happens if the CPUs are started individually?
If the CPUs are started individually, the first CPU will wait indefinitely for the second CPU to join. Similarly, the second and third CPUs will wait for the third CPU to join for up to ten seconds. If the third CPU does not join within this time frame, the two CPUs will continue operating as a pair without the third CPU.

What is required for synchronization between CPUs that start at the same time?
CPUs that start at the same time must use the same application and have the same EE values (stored tunables) for proper synchronization. This ensures consistent behavior and functionality across all synchronized CPUs.
