WIND_TURBINE_LINK
Wind turbine controller adapter: ramped curtailment setpoint, cube-law available-power estimate, high-wind shutdown with a sustained-restart hysteresis, and curtailed-energy accounting.
When to use it
Use WIND_TURBINE_LINK when a wind turbine or small farm is curtailed by a microgrid or grid-constraint dispatch signal, the orchestrator needs an honest figure for the power the wind could have made, and the high-wind shutdown and restart must not cycle the machine at the cut-out speed.

Create a free Ri Tech account to download the block. You get the Structured Text body, the Rockwell Add-On Instruction (.L5X), the Schneider Control Expert DFB (.XDB), PLCopen XML, the IEC 61499 function block type (.fbt) and the datasheet.
Every block in the catalogue is free to download, in every format, with no purchase and no card. Browsing needs no account at all; downloading needs a signed-in one, so the block lands in your library and re-downloads whenever you need it.
Source is never published on this page. The implementation is released to a signed-in Ri Tech account — free of charge, but never anonymously.
