Woodward 9907-162 | 505 Digital Governor Steam Turbine Controller

Description

1. Product Overview

The Woodward 9907-162 is a field-programmable, microprocessor-based 505 Digital Governor Controller designed for the precise speed and load regulation of industrial steam turbines. Acting as the dedicated autonomous automation block for turbomachinery, this hardware executes complex dual-dynamic PID control loops. It samples high-frequency inputs from Magnetic Pickups (MPUs) or proximity probes to accurately modulate admission valves via integrated electro-hydraulic actuator loops.

Engineered with severe-duty operational protection protocols, the 9907-162 incorporates critical machine-safeguarding routines. It features fully configurable automated start-up curves tailored to monitor turbine casing temperatures (hot, warm, and cold thermal conditions). Furthermore, it manages critical speed avoidance bands (3 discrete zones capability), driving the turbine through mechanical resonance windows at maximum acceleration to eliminate structural blade stress and shaft deflection.

Key Applications:

• Industrial Co-generation Plants: Governing extraction steam lines while running parallel generator load-sharing loops.
• Petrochemical Turbo-Compressors: Managing continuous variable-speed processing loops for ethylene, ammonia, or refining gas trains.
• District Heating Stations: Controlling localized back-pressure steam turbines to balance power and thermal grids.
• Marine Propulsion & Auxiliary Drives: Managing emergency backup turbo-generators on commercial marine vessels.

7. FAQ

Q: What is the purpose of the “First-Out” indication feature built into the 9907-162?

The “First-Out” function is an essential troubleshooting tool. When a sudden safety trip occurs and multiple interlocks (e.g., low oil pressure, high vibration, overspeed) open sequentially, the 9907-162 captures the exact event that occurred first down to the millisecond. It displays this primary cause on the screen, cutting down on-site analysis time and preventing guessing during restart procedures.

Q: Can the 9907-162 be programmed directly through the front panel, or does it require an external PC tool?

The unit features full front-panel programmability. Using the integrated 30-key membrane keypad and the text display, engineers can navigate through structured configuration menus, enter tuning parameters, and set scale limits without connecting a computer. For backup and advanced archiving, Woodward’s specialized configuration software can be linked via the serial port.

Q: My existing turbine setup utilizes 20-160 mA hydraulic actuators. Does this model support them directly?

Yes. The 9907-162 features configurable internal current drivers on its actuator output ports. It can be set via the software menus to output standard low-power 4-20 mA signals or high-power 20-160 mA signals, allowing it to interface directly with common Woodward EG, TM, or VariStroke actuators without requiring an external driver amplifier.
