5 MW WTG

[vicemora]

Hello @bjonkman and everyone...
I'm trying to build a more detailed generator model in Simulink to connect it with OpenFAST. I already know how to connect and do the configuration because I review the document "Simulation for Wind Turbine Generators—With FAST and MATLAB-Simulink Modules". The problem is that I cannot find any information about the parameters of a 5 MW electrical generator (because I'm using the 5MW Reference WT). I have barely an "electrical background". Can you help me out with some advice or links, that will guide me to obtain a decent model for a 5MW generator :)?

HI Victor,
You might find the attached file helpful in terms of detailed design parameters for the doubly fed induction generator (DFIG) that is closely representative of the one used in the REPower 5MW turbine (page 348 lists the specifications that you could use for your Simulink model ).

I also found another paper that had used this information to model the generator in Simulink(https://john-klein.github.io/assets/files/journal_papers/journal6.pdf).

NREL also has a generator design tool that we have used to optimize designs at different power levels. It is called GeneratorSE (A link to the report is available here: https://www.nrel.gov/docs/fy17osti/66462.pdf). Page 87 of the report contains a table for DFIG designs at different power ratings including 5-MW . These designs just assumed that the machines were rated for 1200 rpm. Hope you can use these as starting points..

Best,
