Hi folks,
Dyntools in PSSE V34.6 does not have function "outextractdata". I am trying to replace it with "CHNF" but after using function "get_data", chandata only brings the first variable (time) . How I can fix it.
Thanks
Thanks Everyone, I fixed it. The problem was the Out file name in get_data() function:
class ChannelData:
def __init__(self, fileName):
self.timeChannelName = 'time'
temp0 = dyntools.CHNF(fileName , outvrsn = 1)
(short_title, chanid, chandata) = temp0.get_data()
temp = [short_title, dict(), dict()]
temp[1] = dict(chanid).copy()
temp[2] = dict(chandata).copy()
self.fileName = os.path.abspath(fileName)
self.titles = short_title.split("\n")
self.channelNameRef = dict(chanid).copy()
del self.channelNameRef[self.timeChannelName]
self.channelByName = dict([(self.channelNameRef[name], name) for name in self.channelNameRef.keys()])
self.channelData = dict()
self.n = len(temp[2][self.timeChannelName])
for cn in self.channelNameRef.keys():
values = temp[2][cn]
assert(self.n == len(values))
x = numpy.array(values)
if (numpy.isnan(x).any()):
raise Exception('NaN in channel %s' % cn)
self.channelData[cn] = x
self.time = numpy.array(temp[2][self.timeChannelName])
def getTime(self):
return self.time
def readChannel(self, channelName):
k = self.channelByName[channelName]
return self.channelData[k]
The follows are docstrings of the dyntools module in v34.6.1 (PY27 version). Read it and see what you can use.
CLASSES
CHNF
OUTDATA
class CHNF
| This class reads PSSE dynamics simulation studies channel output binary (.out) files, and
| provides methods to access and post process the data from those files.
|
| Methods defined here:
|
| __init__(self, *outfiles, **kwds)
| Create CHNF object as below and apply various methods defined here.
|
| Syntax:
| chnfobj = dyntools.CHNF(*outfiles, **kwds)
|
| Arguments:
| outfiles = Provide one or more PSSE dynamics channel output file names separated by comma.
| At least one file name must be provided.
| Allowed Keywords:
| outvrsn = 0, for no Extended Channel output file type (.out)
| = 1, for Extended Channel output file type (.outx) (default)
|
| csvout(self, channels='', csvfile='', outfile='', ntimestep=1)
| Write PSSE Dynamic Simulation Channel Output File Data to ASCII text file.
| chnfobj.csvout(outfile, channels, csvfile, ntimestep)
| channels = Channel numbers to extract, specified as a channel number or
| list of channel numbers to extract.
| If not specified, all channels are extracted, default.
| csvfile = Data saved to this Text File
| Default extension - .csv
| Default name - outfile name with .csv extension
| outfile = PSSE Dynamic Simulation Channel Output File Name (.out), when not
| provided, used 1st file from the files provided during object creation.
| ntimestep= Number of timesteps per data export, i.e., for every 'ntimestep' data
| is exported. Default=1, i.e., export data for every time step.
|
| get_data(self, channels='', outfile='')
| Return short_title, chanid and chandata for outfile.
| short_title, chanid, chandata = chnfobj.get_data(channels,outfile)
| channels = Channel numbers to extract, specified as a channel number or
| list of channel numbers to extract.
| If not specified, all channels are extracted, default.
| outfile = PSSE Dynamic Simulation Channel Output File Name (.out), when not
| provided, used 1st file from the files provided during object creation.
| Returns
| short_title = String of Short title of the PSSE case
| chanid = Dictionary of Channel IDs, {'time':'Time(s)',1:id1,2:id2,...,n:idn}
| chandata = Dictionary of Channel Data, {'time':[v],1:[v1],2:[v2],...,n:[vn]}
| where 1, 2, ..n are channel numbers available in the input file
| id1, id2, ...idn are the channel identifiers.
| v, v1, v2, ...vn are data values.
|
| get_id(self, outfile='')
| Return short_title and chanid for outfile.
| short_title, chanid = chnfobj.get_id(outfile)
| outfile = PSSE Dynamic Simulation Channel Output File Name (.out), when not
| provided, used 1st file from the files provided during object creation.
| Returns
| short_title = String of Short title of the PSSE case
| chanid = Dictionary of Channel IDs, {'time':'Time(s)',1:id1,2:id2,...,n:idn}
|
| get_range(self, outfile='')
| Return actual minimum and maximum channel values (range) for outfile.
| chanrange = chnfobj.get_range(outfile)
| outfile = PSSE Dynamic Simulation Channel Output File Name (.out), when not
| provided, used 1st file from the files provided during object creation.
| Returns
| chanrange = Dictionary of Channel range values
| = {'time':{'min':v,'max':v},
| 1 :{'min':v,'max':v},......
| n :{'min':v,'max':v} }
| where 1, 2, ..n are channel numbers available in the outfile
| 'min':v are minumum values, and ...can you show a few lines of the code? If it is able to extract 'time', it should be able to extract any other channels.
