GT_CTRL_LINK
Gas-turbine OEM controller adapter with capability clamping, ramp limiting, exhaust-temperature derate and setpoint-deviation supervision.
When to use it
Use GT_CTRL_LINK when a microgrid orchestrator dispatches kW to a gas turbine through its OEM controller (Mark VIe, Woodward, Siemens T3000) over OPC UA or Modbus, and the dispatch must respect the machine's minimum stable load, its ramp capability and its exhaust-temperature derate.
