2014-02-04 18:49:53 -0500 asked a question Parallel-multicore module - load flow

Hi,

Does anyone have the experience of using PSSE parallel-multicore module for loadflow simulation. Is there a difference in using the module as compared to the old single-core module? When I try running some of my python scripts (works on the single-core module), errors such as PSSE not properly initialised.

Thanks

Regards, michael

From within PSSE, my python code has import pssexcel. There seem to be an issue with PSSEv33.4 where the GUI excel icon does not appear. I reverted to PSSE33.3, no issues with importing pssexcel

Hi JervisW,

You may increase the maximum number of iterations to something like 100 or more: Power Flow > Solution > Parameters > ITMXN

2012-01-11 04:35:47 -0500 asked a question Does reactive power of a machine impact on fault levels?

Hi,

My understanding is fault levels are calculated based on the pre-fault voltage & impedances of machine,transformers,lines & shunts. But my question is why when I try to increase the MVAR output of a machine, the fault level changes?

You may try TREE activity

It disconnects all buses that are not syncronously connected to a swing bus and solves the load flow, give it a try, that may do the trick. cheers
