When trying to run RMS simulation with DFIG in Digsilent, the following error pops: output xspeed not initialized. Does anyone know how to address this issue?
Have you defined this signal? If not you need to right click on the synchronous generator and click on define results for rms simulation, then select this signal.
Actually I am not using user defined DSL model. I am using the built-in model given on right side bar of the software window. Do you think this is the flaw?
It can be due to PI controller parameters. Can you just put number of parallel generators as 1 and try to run?
The details of this DFIG modeling is given in chapter 9 of the book, "Power factory applications for power systems". You can refer it for further reference.
