Advanced Steam Turbine Control with Woodward 8200-1302
The Woodward 8200-1302 505D digital governor provides precise control for industrial steam turbines. It integrates a graphical HMI panel and keypad, enabling operators to configure turbine speed, load, and safety parameters. Engineers rely on this module for real-time performance monitoring and predictive maintenance.
Intelligent Control Features and Operating Modes
The 8200-1302 offers three primary operating modes: configuration, operation, and calibration. It supports auto-start sequencing for hot and cold starts, critical speed avoidance in three bands, dual speed and load dynamics, and peak speed detection for overspeed protection. Remote droop adjustment and frequency dead-band control improve turbine efficiency. Additionally, the module includes ten external alarm inputs and ten digital trip inputs for flexible system integration.
Comprehensive Input and Output Interfaces
This digital governor features two redundant speed inputs compatible with magnetic pickups, eddy current probes, or proximity probes. It also provides eight analog inputs configurable for 27 functions, twenty additional contact inputs, two 4–20 mA control outputs, and eight Form-C relay contact outputs. These interfaces allow precise control and monitoring of turbine performance.

Integrated HMI and Graphical User Interface
The Woodward 8200-1302 includes a large 8.4-inch LCD screen with multilingual support, including Chinese, for intuitive operator control. Real-time trending, configurable tag names, and an internal turbine simulator allow engineers to test and optimize performance before live operation. Navigation keys, soft commands, and LED indicators provide clear feedback on system status.
Advanced Communications and Adaptive Algorithms
This module supports Ethernet for connectivity to plant DCS, RemoteView operator panels, and CANOpen for Woodward VariStroke actuators. OptiTune adaptive PID algorithms and acceleration PID controls optimize turbine startup, minimize overshoot, and enhance load rejection performance. High-speed data logging monitors runtime, trip events, and turbine vibrations for proactive maintenance.
