5466-1047 Woodward ProTech 203

The 5466-1047 is a microprocessor-based digital governor controller produced by Woodward, belonging to its classic 505 series.
It is primarily designed for speed control and protection of steam turbines. Below is a detailed introduction to this product:

I. Product Overview

Brand and Model: Woodward 5466-1047
Series: 505 Series Digital Governor
Type: Microprocessor-based controller
Purpose: Specifically designed for steam turbines to control their speed and provide overspeed protection.

II. Core Functions

Speed Control:
- 5466-1047 Precisely controls the speed of steam turbines by adjusting steam inlet flow.
- Supports single-range or split-range actuators to accommodate turbines of different sizes.
Overspeed Protection:
- Incorporates triple independent overspeed protection logic to ensure rapid shutdown in case of overspeed, preventing equipment damage.
- Provides an overspeed test button for convenient on-site testing of protection functions.
Emergency Shutdown:
- Equipped with an emergency stop button for immediate shutdown in emergency situations.
System Protection:
- - Automatically switches control modes upon sensor failure to ensure uninterrupted system operation.
  - Offers local/remote control priority selection to adapt to different operational scenarios.

3. Fully closed-loop control motion controller

By using detection elements such as gratings to detect the position of the controlled unit, transmission errors in the entire

mechanical transmission chain from the motor to the controlled unit can be eliminated, resulting in high static positioning

accuracy. However, due to the nonlinear friction characteristics, rigidity, and clearance of many mechanical transmission links within the

entire control loop, and the large dynamic response time (compared to electrical response time) of the entire mechanical transmission chain,

it is difficult to calibrate the stability of the entire closed-loop system, and the design and adjustment of the motion controller are also quite complex.

Motion controllers are classified based on the nature of the controlled variable and the motion control method:

1. Position control

The position control of the motion controller can be divided into point-to-point motion control and continuous trajectory motion control according to the control principle.

Point position control is a point-to-point positioning control that does not control the motion trajectory between points, nor does it perform processing or

measurement during this process.

Continuous trajectory control is divided into linear control and contour control. Linear control refers to the linear motion of the controlled object in a certain

direction at a certain speed (single axis or multi axis linkage), during which processing or measurement is required; Contour control is the process of

controlling the instantaneous position and velocity of two or more coordinate axes to form a contour curve or surface in a plane or space through linkage.
