'Line' object has no attribute 'get_field' and System' object has no attribute 'Breaker'

[TheASingh]

Hi All,

I was searching for a way to break/disable a Line dynamically while the TDS is running. I found that in Streaming.py, there is a function handle_event(self, Event).

I tried to call it within the Streaming file. I got an error in following line of code (line number 345 in Streaming.py):

bus = self.system.Line.get_field(
                    'bus1', ['Line_' + str(int(idx - 1))])[0]

AttributeError: 'Line' object has no attribute 'get_field'

Then to bypass it, I somehow used a static value for bus variable. Then I got the error in following line of code (line number 355 in Streaming.py)

self.system.Breaker.insert(**param)

AttributeError: 'System' object has no attribute 'Breaker'

Please help me understand why I'm facing these errors? Or is this function still a part of testing/RND?

@TheASingh and @rana253, are you from the same research group? The recent questions seem closely related.

It looks like streaming.py is not up to date. We don't yet support inserting a new device after the system has been set up.

Today, I updated ANDES to version 1.7.3. But still Line object doesn't have attribute 'get_field' and System has no attribute 'Breaker'.

Please guide why I'm not able to successfully invoke the handle_event(self, Event) function.

The functions in streaming.py do not work now. Please see a recent addition to the documentation in Getting Started - Input formats - Disturbances.
