WOODWARD 8290-185 Electrically Powered Governor (EPG) System
1. Product Description
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.

3. Advantages and Features
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.
4. Application Areas and Case Studies
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.
5. Competitor Comparison
Simpler Installation: No hydraulic lines or mechanical linkages required.
Energy Efficiency: Lower power consumption (95 W) than legacy hydraulic systems.
6. Selection Recommendations
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.
7. Precautions
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.
