WOODWARD 9907-1730: Load Sharing Module

 

The WOODWARD 9907-1730 is an isochronous and droop load sharing unit. It’s designed to integrate with existing engine control systems, particularly Caterpillar model engines equipped with digital speed components that process Pulse-Width Modulated (PWM) inputs.

 

Product Overview

 

This module facilitates load sharing between multiple prime movers (like engines or turbines) or between a prime mover and other electronic control systems. It’s a crucial component in power generation or industrial applications where multiple units need to operate in parallel and distribute the load evenly.

  • Product Type: Load Sharing Module
  • Manufacturer: Woodward
  • Part Number: 9907-173 (Note: The search result indicates “9907-173” as the core part number for the Load Sharing Module, while “9907-1730” might be a specific configuration or an extended part number used in certain contexts, but the core functionality points to the 9907-173 Load Sharing Module).
  • Function: Provides isochronous and droop load sharing capabilities.
  • Application: Designed for integration with prime mover systems, particularly Caterpillar engines with digital speed components.
  • Inputs: Features 3-phase CT (Current Transformer) and PT (Potential Transformer) inputs.
  • Power Supply: Requires 18 to 32 VDC.
  • Protection: Protected against reverse voltage, undervoltage, and overvoltage.
  • Certifications: Intended for use with prime mover systems that meet relevant directives and carry the CE mark.

 

Detailed Product Description

 

The WOODWARD 9907-1730 (referring to the 9907-173 Load Sharing Module) is designed to enhance the control capabilities of prime movers, enabling them to work together efficiently in a multi-unit setup.

Here’s a breakdown of its features and how it functions:

  • Load Sharing Capability: This module allows multiple engines or turbines to share a common load. It can operate in both isochronous and droop modes.
    • Isochronous Load Sharing: In this mode, the module works to maintain a constant system frequency (or speed) across all connected units while ensuring they share the load equally. This is critical for stable power generation.
    • Droop Load Sharing: In droop mode, the module allows for a slight, proportional decrease in speed as the load increases. This provides inherent stability in parallel operations, preventing hunting between units. The module can provide a 0-10% speed reduction for droop.
  • Integration with Digital Speed Components: The module is specifically designed to interface with modern engine control systems that use digital speed components and process Pulse-Width Modulated (PWM) inputs. This allows for seamless integration into sophisticated control architectures.
  • Robust Electrical Specifications:
    • Power Supply: The unit operates on a DC power supply ranging from 18 to 32 VDC, with a typical consumption of 5 Watts. It features built-in protection against various voltage irregularities.
    • Inputs: It has 3-phase inputs for both PT (100 to 240 VAC line to line) and CT (3 to 7 Arms at full load), allowing it to monitor the electrical parameters of the system accurately.
  • Enhanced System Control: By integrating this module, operators can achieve:
    • Improved Efficiency: By ensuring optimal load distribution among prime movers.
    • Increased Reliability: By allowing units to back each other up and prevent overload on a single unit.
    • Flexibility: Enabling the integration of other Woodward electronic controls into the system.

In essence, the 9907-1730 (or 9907-173) is a specialized electronic module that plays a vital role in coordinating the operation and load distribution of multiple prime movers, particularly in power generation or heavy industrial applications.
