Woodward 9907-165 505E Digital Governor

Woodward 9907-165 505E Digital Governor is a 32-bit microprocessor-based control system designed for single extraction, extraction/inlet, or inlet steam turbines. It supports field programming, with menu-driven software guiding engineers through configuration for specific generator or mechanical drive applications. The device has turbine control functions and an operator control panel (OCP) that enables configuration, online program adjustments, and turbine/system operation through a two-line display (24 characters per line) and a 30-key keypad on the front panel.

Function & Features

• The 9907-165 controls a variety of turbine parameters including speed (or load), extraction/inlet pressure (or flow), and can control or limit other related process parameters such as turbine inlet pressure/flow, exhaust pressure/flow, generator power output, etc.

• The 9907-165 has a comprehensive operator control panel with a two-line display in English providing instructions for operation, allowing the operator to view actual and setpoint values ​​on the same screen.

• The 9907-165 includes features such as first-out trip indication (5 trip inputs total), critical speed avoidance (2 speed bands), automatic start sequence (hot and cold), dual speed/load dynamics, zero speed detection, overspeed trip peak speed indication, and inter-unit synchronous load sharing.
