10502-000-0-24 Woodward ProTech 203

The 10502-000-0-24 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 10502-000-0-24
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:
- 10502-000-0-24 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.

The testing system adopts two testing methods, online or offline. The software implements intelligent processing module functions,

and the expert system provides solutions for testing problems.

3. Hardware circuit implementation of driver testing system

The testing system mainly includes a measurement and control platform with a computer as the core, as well as a testing platform for installing test drivers, analog loads,

specialized measuring instruments, and other equipment. The circuit design adopts pulse diagnosis anti-interference and redundancy design to ensure accurate and reliable hardware design. The specific connection diagram is as follows:

3.1 Startup Circuit

The startup circuit provides working voltage for the tested driver, and three current limiting resistors are connected in series to prevent surge current. At the same time,

contactors, thermal relays, and filters ensure stable and reliable voltage quality. During the power on process, simply control the computer to issue a power on command,

activate the contactor, complete the power on process, and achieve a safe and reliable “soft start”. The schematic diagram of the startup circuit is shown below.
