Description
WOODWARD 8290-185 Electrically Powered Governor (EPG) System
The
WOODWARD 8290-185 is a high-efficiency digital speed controller designed for gas engines, gasoline engines, and gas turbines in industrial power generation, oil & gas, and mobile equipment applications. As part of Woodward’s Electrically Powered Governor (EPG) series, the
8290-185 eliminates the need for mechanical drives or hydraulic oil systems, offering a compact, cost-effective solution for precise speed regulation. It supports isochronous control, load sharing, and start-fuel limiting, making it ideal for prime movers with low-mass, low-friction fuel linkages.

- Hydraulic-Free Design: Reduces maintenance costs and eliminates oil-related failures.
- High Torque Output: Up to 2.3 J (1.7 ft-lb) for robust fuel control.
- Isochronous Control: Maintains constant speed under varying loads.
- Dual Dynamics: Switch-selectable for optimized response to transient conditions.
- Start-Fuel Limiting: Minimizes smoke during engine startups.
- Wide Temperature Range: Operates reliably in extreme environments.
- Power Generation: Used in backup generators and microgrids for stable frequency control.
- Oil & Gas: Deployed in remote compressor stations to manage gas engine-driven pumps.
- Marine: Controls auxiliary engines on vessels for consistent power supply.
Case Study:
A North American natural gas plant reduced downtime by 15% using the 8290-185 with a 1724 actuator to stabilize turbine speeds during load fluctuations.
- Simpler Installation: No hydraulic lines or mechanical linkages required.
- Flexible Actuator Options: Supports multiple torque outputs (524/1724) compared to single-output alternatives.
- Energy Efficiency: Lower power consumption (95 W) than legacy hydraulic systems.
- Voltage Compatibility: Ensure a 24 VDC power supply is available.
- Actuator Choice: Select the 524 (1.0 J) for lighter loads or the 1724 (2.3 J) for heavy-duty applications.
- Accessories: Add a ramp generator for smoother acceleration/deceleration in generator setups.
- Actuator Alignment: Ensure the actuator’s rotation direction matches the fuel control mechanism.
- Battery Charger: Use a minimum 5 A charger to maintain system reliability.
- Linkage Linearity: Calibrate fuel linkages according to Woodward’s manual 82493 to avoid control errors.
- Environmental Protection: Install in dry, vibration-free enclosures to prevent component damage.
