Woodward 9907-164 505 Digital Governor

Woodward 9907-164 505 Digital Governor

General Description

The 505 microprocessor-based control is designed to control single or dual (split

range) actuator steam turbines (extraction steam turbines require the 505E

version). The 505 is field programmable which allows a single design to be used

in many different control applications and reduces both cost and delivery time. It

uses menu driven software to instruct site engineers on programming the control

to a specific generator or mechanical drive application. The 505 can be

configured to operate as a stand-alone unit or in conjunction with a plant’s

Distributed Control System. 

Additional Features

• First-Out Trip Indication (5 total trip inputs)
• Critical Speed Avoidance (2 speed bands)
• Auto Start Sequence (hot &cold starts)
• Dual Speed/Load Dynamics
• Zero Speed Detection
• Peak Speed
• Indication for Overspeed trip,
• Isochronous Loadsharing between units (with a DSLC™ control)
