WOODWARD 505-8200-1302｜505D Series Digital Governor Turbine Controller ｜
Function
1. Control mode
Speed control: equal time/droop/base load, PID adaptive adjustment
Load control: active power closed-loop, supporting parallel load distribution
Process control: pressure/flow/temperature cascade regulation
Three operating modes: configuration/operation/calibration
2. Key control functions
Automatic start stop sequence: hot start/cold start, with temperature input adaptation
Critical speed avoidance: 3-speed automatic skipping to avoid resonance
Dual dynamic characteristics: speed/load dual PID, fast response to sudden load changes
Remote droop: Remote adjustable droop rate, suitable for parallel connection of multiple machines
Frequency dead zone: Suppress small fluctuations and ensure stable operation
3. Protection and Diagnosis
Overspeed protection: dual redundancy of hardware and software, peak speed recording
Zero speed detection: monitoring of shutdown status
Trip/alarm events: with RTC timestamp for easy traceability
Comprehensive self diagnosis: real-time monitoring of I/O, sensors, actuators, and communication status
4. Operation interface
Graphic LCD: Backlight with high contrast, displaying parameters, trends, and alarms
Buttons: emergency trip, navigation, soft keys, mode switching ESC/Home
Status LED: Running/Fault/Communication/Trip Status Indication
Application
Steam turbines: industrial turbines, power plant small units, cogeneration
Gas turbine: distributed power generation, mechanical drive (compressor/pump)
Ship Power: Main Propulsion Control of Marine Steam/Gas Turbines
Chemical/Refining: Turbine driven compressors, pump group control
Metallurgy/Cement: Waste Heat Recovery Turbine, Fan Drive Control
