Method Detail

setCacheSensitivity

void setCacheSensitivity(boolean b)

Turn on/off sensitivity cache. The cache is on by default.

Parameters:

b - boolean for cache sensitivity

calBusSensitivity

double calBusSensitivity(SenAnalysisType type,
                         java.lang.String injectBusId,
                         java.lang.String busId)
                  throws ReferenceBusException

get bus sensitivity from the cached results. If no existing, calculate the sensitivity. Sensitivity is defined as dAngle(busId)/dP(injectBus).

Parameters:

type - sensitivity type

injectBusId - injection bus id

busId - bus id

Throws:

ReferenceBusException

calBusSensitivity

double calBusSensitivity(SenAnalysisType type,
                         java.lang.String injectBusId,
                         int busSortNumber)
                  throws InterpssException,
                         ReferenceBusException,
                         IpssNumericException

get bus sensitivity from the cached results

Parameters:

type - sensitivity type

injectBusId - injection bus id

busSortNumber - bus sort number

Throws:

InterpssException

ReferenceBusException

IpssNumericException

calGenShiftFactor

double calGenShiftFactor(java.lang.String injectBusId,
                         AclfBranch branch)
                  throws ReferenceBusException

get gen shift factor for the monitoring branch regarding to the injBus and the slack bus as the withdraw bus.

Parameters:

injectBusId - injection bus id

branch - the monitoring branch object

Throws:

ReferenceBusException

getBranchClosurePTDFactor

double getBranchClosurePTDFactor(AclfBranch branch)
                          throws InterpssException,
                                 ReferenceBusException,
                                 IpssNumericException

for an open branch, calculate TPDF for branch closure event analysis

Parameters:

branch - the branch object

Throws:

InterpssException

ReferenceBusException

IpssNumericException

getBranchClosureEquivPreFlow

double getBranchClosureEquivPreFlow(AclfBranch branch)
                             throws InterpssException

for an open branch, calculate equiv pre-contingency flow for branch closure event analysis

Parameters:

branch - the branch object

Throws:

InterpssException
