Woodward 9907-028

Woodward 9907-028 is an important model in the SPM-A Synchronizer series manufactured by Woodward. It is primarily used for grid connection and synchronization of generator sets or large electrical equipment, and serves as a critical component for ensuring power system stability and operational safety.

1. Core Functions

This model is commonly referred to as a Load Sharing Module or a Non-Voltage Matching Synchronizer. Its main responsibilities include:

Phase and Frequency Detection:
Accurately detects the phase angle (±10°) and frequency of the utility grid through internal signal-conditioning circuitry, ensuring the generator is connected to the grid at the correct moment.
Automatic Synchronization Control:
Once grid signals are detected, the module automatically triggers the synchronizing breaker (typically used in conjunction with the 9907-014 relay) to achieve safe and reliable grid connection.
Load Sharing:
When multiple generator sets operate in parallel, the module coordinates load distribution so that each unit shares the electrical load according to preset ratios, ensuring smooth and stable operation.

2. Key Technical Specifications

Voltage Rating:
Typically compatible with 115/230 VAC power supply inputs.
Input Signals:
Equipped with interfaces for current transformers (CTs) and potential transformers (PTs), making it suitable for a wide range of industrial environments.
Communication Interfaces:
Supports RS-485, Modbus, or CANbus protocols (depending on the hardware version), allowing easy integration with PLC or DCS systems.
Control Method:
Utilizes digital control algorithms, offering fast response times and strong resistance to electrical interference.

3. Typical Applications

This device is widely used in the following areas:

Industrial Power Plants:
For generator synchronization, parallel operation, and load sharing.
Marine Power Systems:
Ensures stable generator operation on vessels under varying load conditions.
Microgrids and Distributed Generation:
Suitable for small power stations and distributed energy management systems.
