Woodward 8290-184 EPG Electrically Powered Governor for Diesel & Turbine Engines

Woodward 8290-184 Electrically Powered Governor (EPG) – Precision Speed Control Solution

The Woodward 8290-184 EPG (Electrically Powered Governor) is an advanced speed control system engineered for diesel engines, gas turbines, and other prime movers that lack mechanical governor drive provisions. Utilizing a 24 VDC power supply, this governor delivers isochronous speed regulation with exceptional accuracy and reliability.

Technical Specifications

• Model Number: 8290-184
• Power Supply: 24 VDC
• Control Mode: Isochronous speed control
• Application: Diesel engines, gas turbines, prime movers without mechanical drives
• Output Type: Electrical actuation signal
• Operating Temperature: -40°C to +70°C
• Protection Rating: Industrial-grade environmental protection
• Weight: 0.74 kg

Key Features & Benefits

• Precise Speed Regulation: Maintains stable engine speed under varying load conditions
• Electrical Actuation: Eliminates need for mechanical governor drives, simplifying installation
• Isochronous Control: Ensures consistent frequency output for generator applications
• Compact Design: Space-efficient footprint suitable for retrofit and new installations
• Proven Reliability: Woodward's decades of governor technology expertise

Application Scenarios

The Woodward 8290-184 EPG excels in demanding industrial environments:

• Generator Sets: Prime and standby power generation requiring precise frequency control
• Marine Propulsion: Auxiliary engines and generator drives on vessels
• Industrial Drives: Pumps, compressors, and mechanical drive applications
• Oil & Gas: Wellhead power units and remote site generation
• Data Centers: Backup power systems demanding rapid response and stability
• Manufacturing: Process control applications requiring constant speed operation

Technical Solutions & Integration

The 8290-184 integrates seamlessly with existing control architectures. Its electrical output interfaces directly with fuel actuators, throttle controls, or steam valves, providing proportional control signals based on speed deviation. The system accepts magnetic pickup (MPU) or Hall-effect speed sensors, offering flexibility in sensor selection.

For complex installations requiring load sharing, the EPG supports droop control configurations and can be paralleled with other governors. Integration with SCADA systems is facilitated through optional communication modules, enabling remote monitoring and setpoint adjustment.

Common Questions & Answers

Q: Can the 8290-184 replace a mechanical governor?
A: Yes, the EPG is specifically designed to replace or supplement mechanical governors, particularly in applications where mechanical drive provisions are unavailable or impractical.

Q: What speed sensor types are compatible?
A: The unit accepts standard magnetic pickup (MPU) sensors and Hall-effect sensors. Consult the installation manual for specific sensor requirements and wiring configurations.

Q: Is this suitable for variable speed applications?
A: While optimized for isochronous (constant speed) control, the 8290-184 can be configured for droop mode operation to support load-sharing applications.

Q: What is the typical response time?
A: Response characteristics depend on actuator type and tuning parameters, but typical settling times range from 2-5 seconds for step load changes.
