Application of Woodward 505E Digital Governer

Header pressure control

It can also regulate inlet, extraction, or exhaust header pressures in various steam turbine configurations.


Generator applications

The 505E can be used in turbine generator setups, including automatic synchronizing and generator power limiting.

Industrial steam turbines

The 505E can control industrial steam turbines of various sizes, including those driving generators, compressors, or other mechanical loads.

Turbine speed control

The governor senses turbine speed and adjusts steam flow through actuators to maintain desired speed.

Load control

The 505E can be configured to control turbine load, particularly in applications where multiple steam plant parameters need to be regulated simultaneously.

 

Components of Woodward 505E Digital Governer
 
 
 

Printed Circuit Boards (PCBs)

These are the electronic components that enable the 505E to function and process commands.

 
 

Enclosure

The 505E is typically packaged in an industrial-hardened enclosure designed for mounting in a control panel. An optional NEMA 4X protective frame can provide additional protection.

 
 

Operator Control Panel

This includes a two-line display and 30 keys for operator interaction, such as starting/stopping the turbine and enabling/disabling control modes.

 
 

Input/Output (I/O) Terminals

These provide access for interfacing with various sensors and actuators on the turbine, such as speed probes, steam valves, and other peripherals. The 505E includes discrete (16 contact inputs) and analog (6 programmable current inputs) inputs.

FAQ

 

 

Q: What is the purpose of the Woodward governor?

A: The Woodward PSG governor is a speed-droop governor for controlling speed of small diesel, gas, and gasoline engines, or small steam or industrial gas turbines, isochronously or with droop. The governor is used to control engines or turbines driving alternators, dc generators, pumps, or compressors.

Q: What is Woodward 505?

A: The 505 and 505E are microprocessor-based controls designed to operate steam turbines of all sizes.

Q: What is the purpose of a speed governor on a steam turbine controller?

A: A steam turbine governor is a component of the turbine control system that regulates rotational speed in response to changing load conditions.

Q: What is the Woodward governor in a turbine?

A: Woodward's universal governors (UG) are mechanical-hydraulic governors for controlling diesel, gas or dual-fuel engines, or steam turbines. This proven design has been an industry standard for many years and worldwide acceptance ensures easy servicing in most engine and governor shops.

Q: How do you adjust a Woodward governor?

A: The best way to achieve this is by moving the throttle to full open and noting how the governor shaft moves. If it's clockwise direction, lose the clamp screw and turn the shaft in a clockwise direction with the throttle wide open.
