Woodward 8440-1706 Measuring input SPM-D11 Series Load Share Synchronizer
In grid-connected multi-generator units, accurate measurement of electrical parameters such as voltage, current, and power is crucial for achieving stable load sharing and synchronization. The Woodward 8440-1706 module is designed for this core task. It receives signals from voltage and current transformers and converts them into high-precision digital data for processing by the SPM-D11 main controller.
“Accurate measurement is the foundation of intelligent control,” said a Woodward product manager. “The addition of the 8440-1706 module enables our SPM-D11 series to support a wider range of power generation applications, especially in scenarios with extremely high requirements for power management and system efficiency, such as data center backup power, critical hospital facilities, and industrial manufacturing.”
Core Functions and Advantages:
• High-Precision Measurement: Provides high-precision voltage and current signal measurement, ensuring accurate and rapid response in load distribution and synchronization control.
• Strong Compatibility: As an optional module in the SPM-D11 series, it can be seamlessly integrated into existing systems, easily upgrading system performance.
• Enhanced System Reliability: By providing reliable real-time data, it helps the system prevent overload, reverse power, and other faults, ensuring the stable operation of the entire power generation system.
• Simplified Installation and Maintenance: Modular design facilitates installation, commissioning, and subsequent maintenance, effectively reducing the system's total lifecycle cost.
• Suitable for Harsh Environments: Adhering to Woodward's consistent industrial-grade quality, it can operate stably in harsh environments with vibration, high temperature, and high electromagnetic interference.
Application Scenarios:
The Woodward SPM-D11 series load-sharing synchronizers and their new 8440-1706 measurement input module are ideal for the following applications:
• Parallel operation of multiple diesel/gas generators
• Marine power systems (shore switching, diesel-electric propulsion)
• Isolated microgrids
• Critical facility backup power systems
