RE: [TRNSYS-users] Problem with TYPE190 (HYDROGEMS wind turbine)

[Todd Houstein <toddh@postoffice.utas.edu.au>]

I am using TRNSYS 15 with IISiBat 3 to build a model of a Remote Area Power 
System with two different types of wind turbine. I have previously written 
in about this. Michael Kummert was correct in his reply... I had not given 
the two components unique Logical Unit numbers (thanks Michael!)... Since I 
have corrected this the simulation runs without error. However I now have a 
different problem...

Both wind turbines end up being simulated with the same parameters.

The two components have different external files specified for them. The 
external files have different power vs wind speed relationships defined 
within them. I have tested them individually in a simulation and have 
verified that they are being simulated as desired. But when I put them both 
in the same project together they both take on the parameters from only one 
of the external files. Interestingly, they both take on the parameters from 
the external file of the one that is last in the specified component order!

It looks like you did not change the logical unit number (par(7)) in
Type 190. All logical unit numbers must be given a unique value.

I hope this helps,
