WOODWARD 8200-1300｜Digital Governor System｜
Hardware and Interface
HMI: 8.4-inch color screen, 34 key operation panel, supporting real-time trend, event recording, and first fault display.
Processor and Storage: Embedded CPU, standard program and data storage, supports configuration upload/download.
I/O: speed input (passive/active probe), analog I/O, digital I/O, relay output (to meet the requirements of single/dual actuators).
Communication: Modbus RTU (RS-485/232), supporting integration with DCS/SCADA; Some versions include Ethernet and web servers.
Function
Control capability: 5 sets of PID loops (speed/load, cascade, Aux1/Aux2), supporting automatic crossing of critical speed, load limitation, and grid control.
Start mode: manual/semi-automatic/automatic/remote start, can be triggered by local buttons, external contacts, or communication.
Protection and diagnosis: overspeed protection, first fault indication, sequence of events (SOE) recording, peak speed capture for easy fault location Woodward.
Applicable boundary: Professional extraction/replenishment decoupling control is not supported, and this type of scenario needs to be upgraded to 505XT (such as 8200-1310).
Application
Industrial steam turbines (drive generators, compressors, pumps, fans).
Non extraction/make-up steam units with single valve or double range actuators.
Conventional power systems in industries such as electricity, petrochemicals, metallurgy, and papermaking.
