9907-186 Woodward GS10 Multi-Generator Synchronizer

Product Overview

The Woodward 9907-186 GS10 is a precision-engineered analog load-sharing module designed to manage and balance power distribution across multiple parallel generators. This module ensures system stability by coordinating the output of turbines or engines, preventing any single unit from carrying a disproportionate load. We supply this unit as 100% brand new and original, featuring high-integrity algorithms for both isochronous and droop load-sharing modes. Whether utilized in marine propulsion systems, industrial power plants, or emergency backup networks, the 9907-186 provides the deterministic control necessary for smooth synchronization and transition under varying load conditions.

Technical Specifications

The 9907-186 GS10 delivers robust performance across diverse electrical architectures:

Engineering Advantages

• Precision Distribution Accuracy: The 9907-186 coordinates load sharing with high resolution, utilizing a ±3 VDC speed setting input for ultra-fine frequency and load adjustments. This eliminates "hunting" between parallel units and reduces mechanical stress on the prime movers.

• Dual-Mode Versatility: Operators can toggle between isochronous mode (maintaining constant frequency regardless of load) and droop mode (allowing frequency to drop slightly as load increases). This flexibility allows for seamless integration into either isolated microgrids or parallel connections with a utility utility.

• Extreme Thermal Tolerance: Unlike standard commercial controllers, the 9907-186 operates reliably in temperatures ranging from –40 °C to +85 °C. This makes it an ideal choice for unconditioned engine rooms on marine vessels or remote oil and gas pumping stations.

• Robust Signal Integration: The GS10 architecture accepts a wide range of input signals, including 0.5–4.5 VDC analog and PWM (Pulse Width Modulation). This ensures compatibility with a broad variety of electronic governors and engine control units (ECUs).

FAQs

• Does the Woodward 9907-186 support 50 Hz and 60 Hz systems?

  Yes. The internal circuitry handles both standard industrial frequencies, providing a universal solution for global power generation and marine applications.

• Can I use the 9907-186 for both engines and turbines?

  The module is designed for any prime mover utilized in parallel generation, including diesel engines, gas engines, and steam or gas turbines, provided the governor interface matches the module's input requirements.

• What mounting precautions should I take?

  Woodward recommends installing the module in a ventilated control cabinet. While it features natural convection cooling, maintaining clear airflow around the module ensures it remains within its specified operating temperature range during high-load periods.

• How does the ±3 VDC input improve system performance?

  The ±3 VDC speed setting input allows for very granular adjustments to the governor's speed setting. This high-resolution control is essential for achieving a perfect balance in multi-generator synchronization.
