8200-1300 Woodward turbine controller

The 8200-1300 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 8200-1300
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:
- 8200-1300 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. Target signal and feedback signal

To stabilize a physical quantity in the frequency conversion system at the expected target value, the PID function circuit of the frequency converter

continuously compares the feedback signal with the target signal, and adjusts the output frequency and motor speed in real time based on the

comparison results. So, PID control of frequency converters requires at least two control signals: target signal and feedback signal. The target signal referred

to here is the electrical signal corresponding to the expected stable value of a certain physical quantity, also known as the target value or given value;

The actual value of the physical quantity measured by the sensor is referred to as the feedback signal, also known as the feedback quantity or current value.

The functional diagram of PID control is shown in Figure 2. There is a PID switch in the picture. The PID function can be activated or deactivated by setting the

functional parameters of the frequency converter. When the PID function is effective, the operating frequency is determined by the PID circuit; When the PID function is invalid,

the operating frequency is determined by the frequency setting signal. The working status of PID switches, action selection switches, and feedback signal switching switches is determined by the setting of functional parameters.

4. Target value given

How to transmit the command information of the target value (target signal) to the frequency converter? Various frequency converters have chosen different methods, and there

are generally two solutions: one is the automatic conversion method, which means that when the preset PID function of the frequency converter is effective, the frequency

setting function during open-loop operation is automatically converted to the target value setting.
