8915-024 WOODWARD Debugger unit

The 8915-024 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 8915-024
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:
- 8915-024 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 difference between PWM controller and MPPT controller
In off grid photovoltaic systems, solar charge and discharge controllers are essential for protecting batteries from overcharging and discharging, and extending battery life.

After years of development, the technology of pulse width modulation (PWM) type charging controllers has become very mature. However, we have found that in practical cases,

the power generation of photovoltaic power plants after operation is often lower than the original design value, which not only causes system waste but also brings a lot of inconvenience to application.

How to solve this problem reasonably has brought a challenge to everyone. Some may increase power generation by designing larger solar panels, but this result will inevitably

increase system costs even more. Is there a way to increase power generation without increasing system costs?

MPPT controller is undoubtedly a good choice. The so-called MPPT (Maximum Power Point Tracking) refers to maximum power point tracking.

The maximum power point tracking controller is a device designed in the controller that can perform intelligent calculations and implement real-time tracking to

achieve real-time monitoring of the power generation voltage of the solar panel, and track the highest voltage and current value (VI). By outputting the highest point of electrical energy,

the system charges the battery with the highest efficiency.
