Type-4 Wind Generator Model

I am looking for a model of a Type-4 Wind Generator Model, more specifically a 2 MW example. The closest example I have found is "Wind Farm - Synchronous Generator and Full-Scale Converter (Type 4) Detailed Model". I was wondering if there was every a single Type-4 Wind Generator Model as this is for an important project in which the project supervisor has referred to a single 2 MW example. The opjective of this project is to upscale the model to a more modern 10-15 MW model.

Hi @Callum, I looked into your question about finding a single 2 MW Type-4 Wind Generator model in Simulink, and I think I can help clear things up. So here's the deal - you're actually on the right track with the "Wind Farm - Synchronous Generator and Full-Scale Converter (Type 4) Detailed Model" example you found. The thing is, MathWorks doesn't seem to have published a standalone single turbine example, but the wind farm model you found contains exactly what you need. That wind farm is made up of five individual 2 MW turbines, and each one is a complete, fully detailed Type-4 model. The good news is you can extract a single turbine pretty easily. If you open the model and find the "Wind Turbine Type 4" block, just right-click on it and select "Look Under Mask". You'll see the complete internal structure of one 2 MW turbine with all the components - the synchronous generator, the full-scale converter (diode rectifier, DC-DC boost converter, DC/AC inverter), and all the control systems. You can copy that entire subsystem into a new model and connect it to a simplified grid setup. There are actually two versions you can work with: * The detailed model (power_wind_type_4_det) which uses detailed IGBT models and runs at 2 microsecond time steps - great if you need to look at harmonics and fast dynamics * The average model (power_wind_type_4_avg) which uses averaged converters and runs at 50 microsecond steps - better for longer simulations Your supervisor was probably referring to these individual 2 MW turbine blocks within the farm model, since they're complete standalone units that work perfectly as a starting point. For upscaling to 10-15 MW, you'll need to think about several things. The aerodynamic parameters will change - rotor diameter scales with the square root of power if you keep similar tip speeds. Generator and converter ratings obviously go up, and DC link voltages are typically higher in larger turbines. Control system gains will need adjustment because of the different inertias and structural dynamics. The drivetrain inertia increases quite a bit when you scale up. For reference data on modern large turbines, I'd suggest looking at the DTU 10 MW Reference Wind Turbine, which has open-source parameters, or checking out manufacturer specs for turbines like the Vestas V236-15MW or Siemens Gamesa SG 14-222 DD. The IEC 61400-27-1 standard also has good guidance on Type 4 modeling. Here are some helpful links: MathWorks Wind Turbine Type 4 documentation: https://www.mathworks.com/help/sps/powersys/ref/windturbinetype4.html Wind Farm Type 4 Detailed Model page: https://www.mathworks.com/help/sps/ug/wind-farm-type4-detailed-model.html General Simulink wind power examples: https://www.mathworks.com/help/sps/wind-power.html If you want more detailed component-level guidance, there's also documentation from ESIG (Energy Systems Integration Group) on Type 4 modeling that's based on the Enercon E82 2 MW turbine. My suggestion would be to start by extracting one turbine block, set it up in a simple test model to make sure you understand how it works, and then begin systematically scaling the parameters. You might also want to reach out to MathWorks support - they can be really helpful with specific questions about wind turbine modeling best practices for larger scales. Hope this helps with your project. The upscaling from 2 MW to 10-15 MW is definitely doable, you've just got to be methodical about which parameters need to change and how they relate to each other.
