Multiple Faults (MF) Siemens PSS SINCAL Extended Analysis Modules

Multiple Faults (MF)

Requirements and Use Cases

The individual placement of faults is required for simultaneous fault observations at several points in the network (e.g. to analyze the voltage rise in the event of two separate simultaneous line-to-earth short circuits) as well as faults or interruptions along lines.

• Calculation of faults and line interruptions occurring simultaneously or in short succession at several locations
• Placement of fault observations at nodes or at different positions (fault locations) along a line
• Individual simulation of occurring faults (e.g. two separate simultaneous line-to-earth short circuits as well as 3- and 1-phase auto-reclosure)
• Repeated calculation of identical fault configurations
• Using the results as a basis for setting protection

Solution

The multiple fault calculation (MF) module in PSS®SINCAL allows you to combine individually defined fault observations into multiple faults, calculate them simultaneously and observe their effects.

• Any user-definable fault locations on busbars and lines for short circuit with or without line-to-earth connection and line interruptions
• Any combination of the individual fault observations (and fault types) as fault packages and simultaneous calculation of the occurring fault events
• Switch between the results of the calculation of different fault combinations (fault events)
