Product Description

I. Basic InformationSeries Affiliation

It belongs to Woodward's electronic speed governor series or engine control system components, used for precise control of the rotational speed or load of power equipment such as engines and steam turbines.

Core Functions

Speed Regulation Control: Supports constant speed control (isochronous regulation) or load distribution (droop regulation) modes.
Signal Processing: Receives signals from speed sensors (e.g., magnetoelectric, Hall types) and outputs proportional control signals to actuators (e.g., fuel valves, servo motors).
Protection Functions: Equipped with safety mechanisms such as overspeed protection, low-frequency protection, and emergency shutdown.

Technical Parameters (Refer to Similar Products)

Input Power: Typically 24VDC or 110/220VAC (specific specifications need to be confirmed).
Operating Temperature: -20°C to +70°C (industrial-grade standard).
Communication Interfaces: May support protocols such as RS-232/485, Modbus, and Ethernet.
Output Signals: Analog (e.g., 4-20mA, 0-10V) or digital (relay outputs).

II. Working PrincipleSpeed Feedback Mechanism

The rotational speed of equipment is monitored in real time via speed sensors (as described in Woodward 9907-147), converting mechanical signals into electrical signals (e.g., frequency or voltage signals).
The controller compares the actual rotational speed with the set value, calculates the deviation through a PID algorithm, and adjusts the output signal to drive actuators (e.g., fuel pumps) to regulate power input.

Regulation Modes

Isochronous Regulation:
Maintains a constant rotational speed (e.g., during single-unit operation of generator sets), suitable for scenarios requiring high frequency stability.
Droop Regulation:
Automatically adjusts the rotational speed based on load changes (e.g., proportionally distributing loads when multiple units are paralleled) to avoid system oscillations caused by load grabbing.

III. Application Scenarios

Power Generation Systems: Speed and load control for diesel/gas generator sets.
Marine Propulsion: Main engine speed regulation and propeller load matching.
Industrial Power: Stable operation control for compressors, pumps, and other equipment.
Emergency Power Supplies: Quick start and grid connection of emergency generators.

IV. Common Faults and SolutionsNo Output or Speed Fluctuation

Possible Causes: Sensor failure, PID parameter mismatch, power supply issues.
Troubleshooting Steps:

Check if sensor wiring is loose and use a multimeter to measure signal normality (e.g., magnetoelectric sensors should generate AC voltage varying with rotational speed).
Reset PID parameters to default values and fine-tune proportional (P), integral (I), and derivative (D) coefficients step by step.
Measure whether the input voltage is within the rated range (e.g., 24VDC ±10%).

Overspeed Alarm

Possible Causes: Speed governor failure, actuator jamming, incorrect setting values.
Troubleshooting Steps:

Manually test actuator movement (e.g., closing the fuel valve) and check smooth mechanical connections.
Reset the overspeed threshold via the control panel (typically 110%-115% of the rated speed).
Check if the speed sensor has signal drift (e.g., the actual speed does not exceed the limit, but the sensor gives a false alarm).

Communication Interruption

Possible Causes: Loose wiring, protocol mismatch, module failure.
Troubleshooting Steps:

Check if the shield layer of the communication cable is grounded and replace the cable for testing.
Confirm that parameters such as baud rate and parity bit match the host computer.
Try restarting the controller or restoring factory settings.
