Description

The Woodward 9907-838 is a specialized load sharing module designed to manage proportional real power distribution between multiple generator sets operating in parallel. By monitoring the output of individual units and adjusting the speed control bias, the module ensures that load is balanced across the entire power system. This synchronization is critical for preventing frequency instability and circulating currents, which helps extend the operational lifespan of prime movers by reducing mechanical load imbalances.

Features

Supports both isochronous and droop load-sharing modes for versatile grid integration.
High-speed analog circuitry provides rapid response times to load transients.
Optical isolation is integrated into the signal path to maintain signal integrity against industrial EMI.
Designed for high-vibration environments, ensuring reliable performance in rugged applications.
Minimal thermal footprint allows for dense mounting in standard control enclosures.

Applications

This module is frequently deployed in mission-critical power generation environments, including offshore oil and gas platforms, decentralized power plants, and emergency backup systems for mining and industrial facilities where synchronized load management is required for system stability.

Installation Guidelines

Ensure the module is mounted in a location free from excessive moisture and corrosive gases.
Use shielded cabling for all signal connections to minimize the impact of electromagnetic interference.
Verify that the control power supply is within specified limits before energizing the module.
Always disconnect power before performing wiring changes or removing the module from the mounting rack.
Ensure proper grounding of the module chassis to a common earth point to maintain noise immunity.

FAQ

Q: Does the 9907-838 support isochronous load sharing?
A: Yes, this module is designed to support both isochronous and droop load-sharing configurations to meet various grid requirements.

Q: What is the primary function of this module in a multi-generator system?
A: It ensures that real power (kW) is distributed proportionally among prime movers, preventing imbalances that could lead to frequency fluctuations or engine stress.
