I’m a new gridlabd user and going to the introduction texts and presentations as we speak. I’m really starting to see the possibilities and power of gridlabd but It still not clear for me if there is a possibility to model the low voltage networks connection the houses.
I want to connect serveral houses via a low voltage network (230V or 110V) and measure the parameters in different points of the cable. Is this possible?
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
GridLAB-D does support low voltage systems (only topologically radial, not networked).
To connect to the primary system, you have to use a SINGLE_PHASE_CENTER_TAPPED transformer to step down to 240/120 - descriptions of these can be found on the power flow wiki, or in some of our example files ( http://gridlab-d.svn.sourceforge.net/viewvc/gridlab-d/Taxonomy_Feeders/ ). For connecting to the meter/residence, we typically use a triplex line object. Examples can be found in the same location. Some of these questions are also addressed in the residential course work ( recommend you use: http://gridlab-d.svn.sourceforge.net/viewvc/gridlab-d/course/FourDayCourse/ , as this is the most up-to-date course).
If you want to measure parameters at different points along the line, then you will have to model the lines as a number of separate lines (e.g. you want the voltage 25 ft down a 50 ft line, then break the line into two 25 ft lines).
Hope this helps!
