9905-068 2301A Woodward Generator Load Sharing Module

Product Details

Product Overview

The Woodward 9905-068 operates as a core component of the 2301A series, delivering specialized electronic speed regulation and automatic load sharing for prime movers. This module controls diesel engines, gas turbines, and steam turbines with high dynamic precision. It ensures synchronized frequency stability across multiple parallel-connected generators, directly preventing system instability and power fluctuations. By integrating the 9905-068, operators achieve optimized fuel efficiency and balanced thermal stress across all power units in the network.

Technical Specifications

Engineering Advantages

The 9905-068 solves critical synchronization challenges in isolated and grid-tied power plants. The module utilizes an analog logic architecture that provides near-instantaneous response to load changes, outperforming many digital counterparts in high-vibration environments.

• Dual-Mode Flexibility: The hardware allows seamless switching between Isochronous mode for constant frequency and Droop mode for load-sharing applications with other governors.

• EMI Resilience: The 2301A circuitry incorporates heavy-duty shielding and filtering, allowing reliable installation near high-output alternators and power switchgear without signal corruption.

• Extreme Durability: Designed for marine and industrial engine rooms, the unit operates reliably at 85 deg C, eliminating the need for specialized cooling enclosures in hot turbine decks.

• Precise Load Distribution: The automatic load-sharing logic ensures each generator carries its proportional share of the total demand, preventing "motorizing" of units during low-load periods.

FAQs

• Is the 9905-068 compatible with older 2301 series modules?

  The 2301A (9905-068) serves as a functional upgrade for many legacy 2301 systems; however, you must verify pin-out compatibility and voltage ranges before installation, as the "A" series typically offers enhanced signal conditioning.

• What type of actuators can this module drive?

  The 9905-068 drives standard Woodward proportional actuators. Ensure the actuator current requirements fall within the 9905-068 output specifications to maintain thermal stability.

• How do I calibrate the load sharing in a parallel system?

  Calibration involves adjusting the "Load Gain" and "Speed Trim" potentiometers. We recommend performing these adjustments while the unit is connected to the load sharing lines (L-S lines) to ensure all parallel units communicate correctly.

• Does this unit come with a factory box?

  This specific unit (9905-068 Rev.N) is supplied as Brand New surplus without the original manufacturer's box, though we provide professional industrial-grade packaging to ensure safe transit.
