Product Description

Woodward 5441-693I. Functions

The Woodward 5441-693 is an electronic speed governor or controller, primarily used for speed and load control of power equipment such as diesel engines and gas turbines. Its core function is to receive sensor signals (e.g., speed, load) and external control commands to adjust fuel supply in real time, ensuring stable operation under set conditions. It is widely applied in industrial scenarios requiring high-precision speed regulation.

II. Technical Parameters

Parameter Type	Detailed Description
Power Requirements	- Typically supports DC 24V or AC 110/220V with ±10% voltage fluctuation. - Power consumption: ≤30W, designed for low-power long-term operation.
Input Signals	- Speed feedback: Receives frequency signals (e.g., 0-10kHz) from magnetoelectric sensors or speed encoders. - Control commands: Supports 4-20mA/0-10V DC analog inputs or digital communication (MODBUS, CANopen).
Output Signals	- Fuel regulation signals: Outputs 4-20mA or PWM signals to drive actuators (e.g., Woodward 8273 series). - Status feedback: Provides real-time feedback on parameters like speed and load.
Control Accuracy	- Speed regulation accuracy: ±0.25% of rated speed, meeting high-precision requirements for generator sets. - Response time: ≤50ms for quick adaptation to load changes.
Operating Temperature	-40°C to +85°C, with wide-temperature design for harsh industrial environments (e.g., outdoor, engine rooms).
Protection Level	Typically IP54 for dust and water splash resistance; higher levels customizable for specific models.
Communication Interfaces	Supports RS485/RS232 and Ethernet (e.g., Modbus RTU/TCP) for easy integration into DCS or SCADA systems.
Mechanical Features	- Housing material: Aluminum alloy or engineering plastic, resistant to vibration (10-500Hz, ≤5g) and electromagnetic interference. - Installation: Panel or rail mounting, compact size (approx. 100×100×50mm).

III. Working Principle

The Woodward 5441-693 employs PID closed-loop control logic for speed regulation, operating as follows:

1. Signal Acquisition and Processing

Real-time collection of engine speed sensor signals (e.g., frequency signals from reluctance sensors), compared with set values to generate deviations.
Receives external load commands (e.g., grid dispatch signals) or manual setpoints as control targets.

2. Control Algorithm Operation

Built-in PID controller calculates deviations, combining feedforward control to compensate for sudden load changes and output regulation signals.
Supports parameter customization (e.g., proportional gain, integral time, derivative time) to adapt to different engine characteristics.

3. Execution and Feedback

Outputs electrical signals (e.g., 4-20mA) to drive fuel actuators (e.g., Woodward 8273) for adjusting fuel valve openings.
Feedback actuator status via position sensors (e.g., LVDT) to form a closed loop, ensuring regulation accuracy.

4. Protection Functions

Built-in overspeed protection (triggers shutdown at ≥110% rated speed), undervoltage protection, and sensor fault diagnosis.
Supports fault code display for convenient maintenance and troubleshooting.

IV. Application Scenarios1. Power Generation

Speed control for diesel and gas turbine generator sets to maintain grid frequency stability (e.g., 50Hz/60Hz).
Load distribution regulation during parallel operation to ensure collaborative performance of multiple units.

2. Oil & Gas

Speed control for engines driving oil pumps and compressors, adapting to pipeline pressure fluctuations and process load changes.
Stable control of emergency power generation equipment in oil fields.

3. Marine & Offshore

Speed control systems for main and auxiliary marine engines, resisting wave impacts and propeller load variations.
Frequency stability control for offshore platform generators.

4. Industrial Drives

Speed regulation for engine-driven equipment (fans, pumps, compressors) based on process requirements (e.g., constant pressure water supply, flow control).

V. Comparative Advantages

High-precision control: PID algorithm + dynamic compensation ensures speed fluctuation <±0.5%, outperforming traditional mechanical governors.
Intelligent integration: Supports digital communication and remote monitoring for IIoT system integration.
Flexibility: Parameters customizable via software (e.g., Woodward ProAct) to adapt to different engine models.
Reliability: Industrial-grade components with MTBF ≥50,000 hours, suitable for continuous operation.
Convenient maintenance: Enables online parameter modification and self-diagnosis, reducing downtime.
