ElmZone attributesPowerFactory Zone

Every attribute of the PowerFactory Zone (ElmZone): 16 input parameters and 314 result variables, with units and meaning. Copy a name into GetAttribute or SetAttribute.

What ElmZone is

A zone: a group of elements for summary results and for scaling loads and generation of one part of the network together.

Class: ElmZone, element class
PowerFactory name: Zone
Attributes: 16 input parameters and 314 result variables, in 6 calculations

Read and write ElmZone in Python

import powerfactory

app = powerfactory.GetApplication()          # GetApplicationExt() from outside PowerFactory

for obj in app.GetCalcRelevantObjects("*.ElmZone"):
    print(obj.loc_name, obj.GetAttribute("loc_name")) # Name

obj = app.GetCalcRelevantObjects("*.ElmZone")[0]
obj.SetAttribute("loc_name", "Zone 1")        # rename the zone

An input parameter is read and written with or without its e: prefix: GetAttribute("outserv") and GetAttribute("e:outserv") give the same value.
RMS and EMT variables change over time: record them in a results object (ElmRes) to read the whole curve. GetAttribute after a run gives the value at the last time step.

ElmZone input parameters

The element data, as typed in GetAttribute and SetAttribute (the e: prefix is optional). Setting one changes the model.
