Woodward 8200-1302 505D Digital Governor Turbine Control

Key Features

  • Integrated Graphical HMI: The 8.4 – inch LCD screen supports multi – language display, real – time parameter trending, and configurable tag names for easy navigation and troubleshooting. It can record RTC – time – stamped trip/alarm events.
  • Comprehensive Turbine Control: It has automatic start sequencing for hot/cold starts (with temperature input support), critical speed avoidance across 3 speed bands, dual speed/load dynamics tuning, zero – speed detection, and overspeed trip peak – speed indication. It also features frequency dead – band and remote droop adjustment.
  • Safety & Monitoring: It is equipped with 10 external alarm inputs and 10 external DI trip inputs, and has a dedicated trip indication with time – stamping for post – event analysis. It also has built – in overspeed protection and a fault – tolerant architecture.
  • Flexible I/O Configuration: 8 analog inputs (configurable for 27 functions), 20 contact inputs, 2 analog outputs, and 8 Form – C relays allow for customized integration with sensors, actuators, and safety systems.
  • Communication & Diagnostics: It supports Modbus for PLC/DCS integration, and has data logging and RemoteView remote monitoring capabilities. It offers 3 operating modes: configuration, operation, and calibration.
  • Hazardous Area & Marine Ready: It meets ATEX Zone 2 and IACS UR E10 marine compliance standards, making it suitable for harsh and classified environments.

Application Scenarios

  • Marine Steam Turbines: Used for main propulsion and auxiliary power generation systems on commercial ships, meeting IACS marine certification requirements.
  • Industrial Steam Turbines: Applied in power plants, refineries, chemical plants, and pulp/paper mills for process steam and on – site power generation.
  • Hazardous Area Installations: Suitable for ATEX Zone 2 facilities like offshore platforms and petrochemical plants where explosive atmospheres may exist.
  • Cogeneration Systems: Utilized in combined heat and power (CHP) plants to control turbine speed and load for efficient energy utilization.
  • Retrofit Projects: Serves as a drop – in replacement for legacy 505 governors, upgrading control capabilities while maintaining compatibility with existing turbine hardware.

Configuration & Maintenance

  • Configuration Tool: Configurable via the front – panel HMI or Woodward ToolKit software with USB connectivity.
  • Security: Password – protected access prevents unauthorized changes to critical control parameters.
  • Data Management: It can log trip events, performance trends, and operational data for predictive maintenance and compliance reporting.
  • Redundancy: Dual redundant speed inputs ensure reliable operation even if one sensor fails.
