The 8262-1143’s triple-redundant, fault-tolerant design allows it to continue operating the turbine safety under any single point of failure. Modular design and hot-swapping capability allow maximum uptime and minimize maintenance shutdowns required for the control.  The 8262-1143 control’s unique PID structure makes it ideal for applications requiring accurate control of parameters such as turbine speed, load, extraction header pressure, inlet header pressure, and exhaust header pressure or tie-line power.

This field programmable controller allows users to easily make system configuration changes without the need of an OEM expert. The system can be controlled, configured, calibrated and tuned using the optional 17” touchscreen display or any workstation running Woodward’s RemoteView software. RemoteView can also function as an HMI for the system, allowing operators to monitor the system, start/stop the turbine, enable/disable all control modes, and view/reset system alarms.

Applications:
Speed/frequency control
Turbine or generator load control/limiting
Extraction and/or admission header pressure control
Turbine inlet header pressure control/limiting
Turbine exhaust header pressure control/limiting
Plant import/export power control/limiting
Isochronous load sharing between units
Any process directly related to unit load
Proportional or integrating Servo Position Control with LVDT/RVDT excitation (with optional modules)
