Pietro,
· PV pumping systems requires two kind of power
conditioning systems when connected to battery and AC pump,
charge regulator and DC-AC inverter with MPPT. What I
understood is that the power conditioning system that can be
found in the Trnsys library models both. Is it right? Which
is the connections scheme between Type 48c and a battery? I
had problems in running the software and displaying the
energy stored in the battery and the SOC of the battery.
Your understanding is correct. I am not sure why you had problems
getting the battery and charge controller to work properly and would
recommend that you send your project to your distributor for
assistance.
· In the case I want to simulate a DC-DC
controller, how can I do?
there is a fairly generic power conditioning model in the standard
Electrical library; look at Type175. Depending on what your
controller does, it may be necessary to write your own component. I
have had to do this in a number of situations where I had a complex
master controller that was dealing with a bunch of different input
sources and loads.
· Both DC and AC motor-pumps have a flow-speed
that depends on the power input, how can I simulate it in
trnsys?
there are a number of pump models in the TESS Hydronics Library that
take power as an input and determine flow. Look at Types745, 746,
and 749.
Kind regards,
David
