pandapower

import from pandapower

The plugin can automatically detect if you are importing a pandapower or pandapipes network, it will show only relevant settings.

• crs - coordinate reference system

Selecting the appropriate crs is required as pandapower does not store this information by default.

The crs for the resulting GeoJSON is taken from the QGIS Project. GeoJSON has deprecated support for crs, WGS-84 is highly recommended. If a specific crs is preferred it is recommended to create a Project with that crs first and then import the network.

• run pandapower

If this option is selected pandapower.runpp() is executed before exporting any data.

• color lines by load

If this option is selected the network is coloured by load for each line individually. If not the different voltage levels are colored in different colors.

• Select save folder

If no folder is selected the network will be loaded into QGIS from memory. The network then can not be edited directly. If a folder is selected each layer will be saved there as a GeoJSON file and then loaded into QGIS. The network can then be edited directly from within QGIS. It is recommended to select a save folder.

type	string	b
zone	string	None
in_service	boolean	True
max_vm_pu	float	NAN
min_vm_pu	float	NAN

export to pandapower

• Name

This is optional. The name is set when creating the pandapower network

• Frequency

Default value: 50
The Frequency of the network in Hz.

• Reference apparent power p.U.

Default value: 1
The Reference apparent power per Unit.

• add standard types

If selected the pandapower standard types are added to the network.

• Select layers to export

The plugin attempts to export all selected layers. It will export all features of vector layers that have pp_type set to bus or line.

pandapipes

import from pandapipes

The plugin can automatically detect if you are importing a pandapower or pandapipes network, it will show only relevant settings.

• crs - coordinate reference system

Selecting the appropriate crs is required as pandapipes does not store this information by default.

• run pandapipes

If this option is selected pandapipes.runpp() is executed before exporting any data.

• color pipes by pressure

If this option is selected the network is coloured by pressure for each line individually. If not the different pressure levels are colored in different colors.

• Select save folder

If no folder is selected the network will be loaded into QGIS from memory. The network then can not be edited directly. If a folder is selected each layer will be saved there as a GeoJSON file and then loaded into QGIS. The network can then be edited directly from within QGIS.

export to pandapipes

• Name

This is optional. The name is set when creating the pandapower network

• Fluid

If the fluid is in the standard library this is used to create the pipes. If not the pipes are created using the properties from the attributes table.

• add standard types

If selected the pandapipes standard types are added to the network.

• Select layers to export

The plugin attempts to export all selected layers. It will export all features of vector layers that have pp_type set to junction or pipe.

pandapower-qgis's Issues

[feature] value constraints for known fields

It is possible to set value constraints for attributes on QGis layers.

---

For bus layers

name	type	values	features
pp_type	QString	"bus" or "line"
pp_index	int		enforce unique (for bus layers only if possible)
in_service	double	1 or 0

---

for line layers

name	type	values	features
pp_type	QString	"bus" or "line"
pp_index	int		enforce unique (for line layers only if possible)
in_service	double	1 or 0

possibly limit std_type to a known string if metadata can be added to qgis

fluid field shown

when first opening the export dialog it should be in power export mode, but the fluid field is visible.
After switching it works correctly.

Make all layers de-/selectable with one click

Hi,

if there are many layers and you only want one or two selected, its quite annoying to deselect all of them.
So I would suggest a button for selecting / deselecting all layers.

BR

No or partial geodata leads to crash.

If the network only contains a subset of geodata (not every bus and line has geodata) QGIS might crash or return a Stacktrace.

This should be fixed with a Warningmessage and continued by loading available data.

Need of example files to import and export

I couldn't import any of the examples from pandapowers, e.g. mv_oberrhein
It always gives errors.

Is it possible top have one or two working examples on both import and export?

One JSON file and one SHP or gpkg file

Thanks

typo in apparent

there is a typo in the word apparent in the export dialog.

Set SN_MVA = 1

Hi,

pandapower normally expects an sn_mva = 1, currently it is configurable and set to 1000.
Just remove the box and set it straight to one.
