9907-005 is a Master Synchronizer and Load Control Module manufactured and designed by Woodward as part of the 9900 Series used in Turbine Control Systems. A Master Synchronizer and Load Control Module, often referred to as a synchronization and load control system, is a crucial component in electrical power systems and generators. It plays a vital role in ensuring the safe and efficient operation of multiple generators that are connected in parallel to supply power to a common electrical grid or load. Here's an overview of its functions and importance:


  • One of the primary functions of the Master Synchronizer is to synchronize multiple generators that are intended to operate in parallel. This involves matching the voltage, frequency, and phase of each generator with the grid or another generator.
  • Synchronization is essential to avoid electrical disturbances, such as voltage spikes or frequency fluctuations, which can damage equipment and disrupt power supply.

Load Sharing:

  • The Load Control Module part of the system is responsible for managing the distribution of electrical load among the synchronized generators.
  • It ensures that each generator shares the load proportionally based on its capacity and ensures that no generator is overloaded or underloaded. This optimizes the efficiency and longevity of the generators.


  • The system provides protection features to prevent overloading, overvoltage, and other electrical faults that could damage the generators or the connected electrical grid.
  • It can disconnect a generator from the parallel operation in case of an emergency or fault to protect the system.

Automatic Control:

  • Modern Master Synchronizers and Load Control Modules often feature automatic control capabilities. They can automatically start or stop generators based on the load demand.
  • This automation helps maintain a stable and reliable power supply without the need for constant manual intervention.

Data Monitoring and Analysis:

  • These systems often include monitoring and data logging functions to keep track of critical parameters like voltage, frequency, and load conditions.
  • Data analysis can help identify trends, anticipate potential issues, and optimize the performance of the generators and the electrical grid.

 Human-Machine Interface (HMI):

  • Users and operators can interact with the system through a user-friendly interface. This HMI provides real-time information, control options, and alarms in case of deviations from normal operating conditions.

Synchronization Standards:

  • These systems adhere to international synchronization standards, such as IEEE 1547, to ensure compatibility and safe operation when connecting generators to the grid.
