Dr. Zimerman at al.,
I beleive more clarification needs to be added. The MATPOWER uses a
single phase model (in sequence domain) that specifically is "positive
sequence model" of the three phase symmetrical and balanced power
system model.
As many people on this Forum ask questions about "distribution system,
radial system, unbalance system etc.) the single phase model could be a
there phase model with single phase loads (there phase domain; model
that MATPOWER does not model) that could have single phase losses
calcualtions per each of the phases.
As there is clerlly defined method fo calulating losses for "sequence
domain" losses, there is no set criteria for calculation of losses in
"three phase domani" per phase losses (issue with mutual coupling of
resistive componnets and inclusion in summation).

This is a question of what you are modeling. MATPOWER only deals
with a single phase model. If you are using it to model a balanced
3-phase system, then it is up to you to handle the mapping of
parameters and results between the single-phase representation and the
actual 3-phase model. I suggest you consult a good power systems
analysis textbook to understand the correspondence between the two
(which is what I’d need to do to refresh my memory).

Hi all,
I want to know if the value of total power losses in the results of
power flow is the three phase loss value, or is the single phase loss
value and to obtain the three phase value i have to multiply it by 3
