mp.dme_xfmr3p

class mp.dme_xfmr3p

Bases: mp.dm_element

mp.dme_xfmr3p - Data model element for 3-phase transformer.

Implements the data element model for 3-phase transformer elements.

Adds the following columns in the main data table, found in the tab property:

Name	Type	Description
bus_fr	integer	bus ID (uid) of “from” 3-phase bus
bus_to	integer	bus ID (uid) of “to” 3-phase bus
r	double	series resistance (p.u.)
x	double	series reactance (p.u.)
base_kva	double	transformer kVA base (kVA)
base_kv	double	transformer kV base (kV)
tm	double	transformer off-nominal turns ratio
pl1_fr	double	phase 1 active power injection at “from” end (kW)
ql1_fr	double	phase 1 reactive power injection at “from” end (kVAr)
pl2_fr	double	phase 2 active power injection at “from” end (kW)
ql2_fr	double	phase 2 reactive power injection at “from” end (kVAr)
pl3_fr	double	phase 3 active power injection at “from” end (kW)
ql3_fr	double	phase 3 reactive power injection at “from” end (kVAr)
pl1_to	double	phase 1 active power injection at “to” end (kW)
ql1_to	double	phase 1 reactive power injection at “to” end (kVAr)
pl2_to	double	phase 2 active power injection at “to” end (kW)
ql2_to	double	phase 2 reactive power injection at “to” end (kVAr)
pl3_to	double	phase 3 active power injection at “to” end (kW)
ql3_to	double	phase 3 reactive power injection at “to” end (kVAr)
