Why is the current from the wind farm not uniform when using multiple wind turbines.

25 views (last 30 days)
Good Day, I have been using the type 4 wind farm from the example " Wind Farm - Synchronous Genenerator and Full Scale Converter(Type 4) Detailed Model" but when I use multiple wind turbines I find the output is unstable and I am not sure what could be causing this.
I have included screen shots below.
Figure1 showing the circuit and parramiters used
figure2 showing the results when using 1 turbine
figure3 sowing the circuit and paramiters using 33 wind tirbines
figure 4 showing the results of using 33 wind turbines
figure5 showing zoomed version of what takes place in figure4
Figure 5 showing a zoomed version of the results using 33 wind turbines

Hi Joseph The individual turbines might get wind speed that is not equal but follow a given distribution with a mean value of 30m/s. The results of currents shown reflect this reality. Regards Juan

Thank you, I will keep that in mind. Do you have any sugestions that may help me to reduce the fluctuations.

Hi there, I have not looked into the example in detail. But maybe you can try to add more load (power consumers) into the grid, see if this damps current fluctuations. Br Juan
