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 |
2014-02-04 18:35:38 -0500 | commented answer | import pssexcel 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 |

2012-01-11 04:45:42 -0500 | answered a question | reattempt solve if iteration limit is reached Hi JervisW, You may increase the maximum number of iterations to something like 100 or more: Power Flow > Solution > Parameters > ITMXN regards, chiangm |
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? |

2012-01-08 02:40:42 -0500 | answered a question | Crash when in service line to out of service bus ASCC 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 regards, michael |
