Hi. I was wondering if you have the ABB Unitrol F AVR in your library. If not can you recommend a similar alternative?
Thanks.

It is highly possible that either we have it or something similar can be used. Can you forward to us the control diagram, then, we would be definite in our recommendation.

You can email it to me at adib@edsa.com or fax it to (858) 675-9724

The model of Unitrol in edsa library is "ST5B-AVR", Please note the following:

1) We will send you a revised model later today

2) Please make sure that you enter the manufacturer parameters, otherwise the model will not work.

It is not possible to use the deafult values. One set of values we used which work fine are:
Tr=0.05,
TC1=TB1=TB2=TC2=1.0
VRMAX=10,
VRMIN=-10.0,
KC=0.1,
T1=0.05,
KR=1.0

3) In the modified model we will send you, VRMIN for this model can be negative, we are changing the limits of VRMIN to -100 to 100
