Woodward 9907-029 SPM-A Synchronizer Module

The Woodward 9907-029 SPM-A Synchronizer is an electronic synchronization controller developed for generator paralleling applications.

The module monitors generator voltage and bus voltage, compares frequency and phase differences, and provides correction signals to the engine governor or speed control system. This allows the generator to reach synchronization conditions before connecting to the power bus.

The SPM-A series is widely applied in systems where automatic synchronization, stable generator connection, and reduced mechanical/electrical stress are required. It can work with Woodward 2301A speed control systems and other compatible generator control equipment. 

Automatic Generator Synchronization

The 9907-029 automatically controls synchronization conditions by monitoring:

• Generator frequency

• Bus frequency

• Voltage difference

• Phase angle difference

This allows generators to connect safely to the power system.

Accurate Frequency Matching

The synchronizer provides speed correction signals to the governor system to achieve stable frequency matching before breaker operation.

Advantages include:

• Reduced synchronization time

• Improved generator stability

• Lower mechanical stress

Voltage and Phase Control

The module supports voltage matching and phase adjustment functions to improve generator paralleling reliability.

Adjustable Synchronization Parameters

Engineers can configure operating parameters according to different generator sizes and prime mover characteristics.

Suitable for:

• Diesel generators

• Gas engines

• Turbine generator systems

Reliable Power Connection
