Setting up pitch control , how?
Hello,
I am fairly new to QBlade and want to set up pitch control for the 5 MW NREL Turbine. What options do I have and wich pitch control would you recommend? How do I set it up?
Thanks in advance!
Hello,
there are several way in QBlade to simulate pitch control:
1. Fixed pitch in steady state BEM analysis, or BEM turbine analysis: You can define a fixed pitch in any BEM simulation. Simulating across several windspeeds allows you to generate the steady state power curve for a turbine, influenced by the blade pitch.
2. Prescribed pitch: You can prscribe the blade pitch over time in a time domain simulation. This can be done by including a “Simulation Input File” with a simulation. https://docs.qblade.org/src/user/simulation/simulation.html#turbine-events-and-operation.
3. Including a turbine controller: If you have an aeroelastic definition of your turbine you can include a turbine controller with a time domain simulation. In this case the turbine controller will take over the blade pitch control to regulate power, and/or to reduce loads (individual pitch control, IPC).
4. Running QBlade in the Simulation in Loop Interface (SIL): Running QBlade in the SIL allows you to set the blade pitch based on a user defined function during the simulation.
I recommend checking out the documentation for detailed information on each of these approaches.
BR,
David
