Function DoSteppedEvent

 

Function DoSteppedEvent (ByVal nDevHnd&, ByRef vdFltOpt() as Double, _

               ByRef vnOpt() As Long, ByVal nTiers as Long ) As Long

Purpose: Simulate one or more faults.

Works in:      OneLiner only.

Parameters:     

nDevHnd       [in] handle of a bus or a relay group.

vdFltOpt    [in] fault simulation options
vdFltOpt (1) – Fault connection code
                   1=3LG
                        2=2LG_BC,3=2LG_CA,4=2LG_AB
                        5=1LG_A,6=1LG_B,7=1LG_C
                   8=LL_BC,9=LL_CA,10=LL_AB

vdFltOpt (2) – Intermediate percent between 0.01-99.99. 0 for a close-in fault. This parameter is ignored if nDevHnd is a bus handle.

vdFltOpt (3) – Fault resistance, ohm

vdFltOpt (4) – Fault reactance, ohm

vdFltOpt (4+1) – Zero or Fault connection code for additional user event

vdFltOpt (4+2) – Time  of additional user event, seconds.

vdFltOpt (4+3) – Fault resistance in additional user event, ohm

vdFltOpt (4+4) – Fault reactance in additional user event, ohm

vdFltOpt (4+5) – Zero or Fault connection code for additional user event

vnOpt       [in] Study options flags. 1 – set; 0 - reset
vnOpt (1)  - Consider OCGnd operations
vnOpt (2)  -
Consider OCPh operations
vnOpt (3)  -
Consider DSGnd operations
vnOpt (4)  -
Consider DSPh operations
vnOpt (5)  -
Consider Protection scheme operations

nTiers      [in] Study extent

Return value:

1               success

0               failure

Remarks: After successful completin of DoSteppedEvent()you must call function GetSteppedEvent() to retrieve detailed result of each step in the simulation.

Example:

 

  vdFltOpt(1) = 5    '1LG phase A

  vdFltOpt(2) = 10   'Intermediate percent between 0.01-99.99

  vdFltOpt(3) = 0    'Fault resistance

  vdFltOpt(4) = 0    'Fault reactance

  vdFltOpt(5) = 0    'Zero or nFltconn of additional event

  vnDevOpt(1) = 1    'Consider OCGnd

  vnDevOpt(2) = 1    'Consider OCPh

  vnDevOpt(3) = 1    'Consider DSGnd

  vnDevOpt(4) = 1    'Consider DSPh

  nTiers& = 5

  If 0 = DoSteppedEvent( nBusHnd, vdFltOpt, vnDevOpt, nTiers ) Then GoTo HasError

  ' Call GetSteppedEvent with 0 to get total number of events simulated

  nSteps = GetSteppedEvent( 0, dTime#, dCurrent#, nUserEvwent&, sEventDesc$, sFaultDest$ )

 

  Print "Stepped-event simulation completed successfully with ", nSteps-1, " events"

  For ii = 1 to nSteps

  Call GetSteppedEvent( ii, dTime#, dCurrent#, nUserEvwent&, sEventDesc$, sFaultDest$ )

    Print "Fault: ", sFaultDest$

    Print sEventDesc$

    Print "Time = ", dTime, " Current= ", dCurrent

  Next

  Stop

  HasError:

  Print "Error: ", ErrorString( )

  Stop
