3005-517 Woodward turbine controller

The 3005-517 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 3005-517
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:
- 3005-517 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.

Most loads, whether inductive or capacitive, require a modulation frequency higher than 10Hz. Imagine if a light bulb were to be turned on for 5 seconds,

then turned off for 5 seconds, and then turned on and off again. The duty cycle is still 50%, but the bulb will light up in the first 5 seconds

and turn off in the next 5 seconds. To achieve a power supply effect of 4.5V voltage for the light bulb, the on-off cycle period must be sufficiently short compared to the response time of the load to switch state changes. To achieve the effect of

dimming the light (but keep it on), it is necessary to increase the modulation frequency. The same requirements also apply in other PWM applications. The usual modulation frequency is between 1kHz and 200kHz.
hardware controller
Many microcontrollers contain PWM controllers internally. For example, Microchip”s PIC16C67 contains two PWM controllers, each of which can choose

the on-time and cycle. Duty cycle is the ratio of on-time to cycle; The modulation frequency is the reciprocal of the period. Before performing PWM operations, this microprocessor requires the following tasks to be completed in software:
