Python Plant Extract Document processor

Project description

Plant Extract Document processor
================================
A package for interacting with and creating [SunSpec](http://sunspec.org)
Plant Extract Documents and the standard blocks contained therein.

Installation
------------
Using pip::

pip install plantextract

Usage
-------
Typical `parse` usage looks like this::

#!/usr/bin/env python

from pedparser import ModelIDValues, PointIDValues
import plantextract.pedparser
...

this_dir, this_filename = os.path.split(__file__)
ped_file = os.path.join(this_dir, 'examples', 'ped-kitchen-sink.xml')
parser = pedparser.PlantExtractParser()
parser.parse(ped_file=ped_file)
parser.ped.plant # the Plant block
parser.ped.plant.name # the Plant's name attribute
parser.ped.plant.location.city # the Plant's location city attribute

# get ENERGY Points that are from an INVERTER_SINGLE_PHASE Model
points = parser.match_model_points(
model_id=ModelIDValues.INVERTER_SINGLE_PHASE,
point_ids=[PointIDValues.ENERGY]
)
print('Retrieved point:', points[0].id, points[0].value())
print('Point scale factor:', points[0].sf)
print('Point value:', points[0].value()) # another way to get Point value

# get ENERGY Points that are from an INVERTER_SINGLE_PHASE Model, but only
# if the Device containing the Model has a logger ID of '11:22:33:44:55:66'
points = parser.match_model_points(
model_id=ModelIDValues.INVERTER_SINGLE_PHASE,
logger_id='11:22:33:44:55:66',
point_ids=[PointIDValues.ENERGY, PointIDValues.POWER]
)
print('Retrieved point:', points[0].id, points[0].value())
# ...etc...

# ...or one can directly interact with the sunSpecData block
print parser.ped.sunSpecData.d # the DeviceRecords list in the sunSpecData
print parser.ped.sunSpecData.d[0].m # the Models list in the Zero'th Device
print parser.ped.sunSpecData.d[0].m[0].p[0].id # the ID of the Zero'th Point
# ...etc...


Typical `create` usage looks like this:

#!/usr/bin/env python

from plantextract.ped import PlantExtract, Plant, Location
from plantextract.ped import NamePlate, Array, Equipment

ped = PlantExtract(
Plant(
uuid4(),
activation_date="2013-03-02",
location=Location(latitude=1.1, longitude=2.2,
city="Redwood City",
state_province="CA"),
name_plate=NamePlate(props=[
Property('installedDCCapacity', 'float', '6.5'),
Property('installedACCapacity', 'float', '6.4')
]),
design_elements=DesignElements(props=[
Property('plantType', 'string', 'commercial')
]),
array=Array(props=[
Property('description','string','Carport')
], array_id=1),
equipment=Equipment(props=[
Property('Mn', 'string', 'MeterManuf'),
Property('Md', 'string', 'MeterModel'),
Property('uncertainty', 'float', '0.5')
], equipment_type='meter')
)
)

Requires [PyXB](http://pyxb.sourceforge.net) 1.2.3
