#808 Powerflow doesn't properly handle faults on already faulted devices,

[nikhilgupta10]

Under the current implementation, if a faulting event occurs on an already faulted item, it is ignored (e.g., phase A is out of service because a fuse blew, then another phase A fault occurs downstream while this is out of service -- no actual fault occurs, but he tree is still leaning on the line).

This is likely more of a \how powerflow handles eventgen calls\ than an explicit reliability fix.

nikhilgupta10 imported these comments from Sourceforge: "ftuffner":Potential approaches to the fix may be making eventgen less \check at end and beginning of events\ and more hese events are in progress.\ An alternative is to expand the object and phase tracking capability already in powerflow to support this. All of these items may become moot if anticipated functionality of the NEV solver and protective devices are implemented, since they may change the fundamental nature of how reliability and powerflow interact.
