Short Circuit (SC) Siemens PSS SINCAL Core Modules

Description

Short Circuit (SC) Siemens PSS SINCAL Core Modules

Short Circuit (SC)

Requirements and Use Cases

The calculation of short-circuits in networks during planning and operation to assess the load on the equipment must be carried out according to standardized procedures. The results obtained in this way are also required as a basis for further analysis (e.g. protection concept, arc flash evaluation).

  • Dimensioning of the equipment according to the expected thermal and mechanical stress in case of short circuits (maximum short circuit currents)
  • Determination of the protection setting based on the results (minimum short-circuit currents)
  • Arc flash evaluation based on the calculation results
  • Calculation of short circuits under initial load

Solution

The short circuit calculation (SC) module in PSS?SINCAL allows the calculation of short circuits according to standardized procedures and standards. The calculation and its results are then available to be used by other modules.

  • Modeling of the network elements for the short circuit calculation according to the listed standardized procedures and standards
  • Short circuit calculation for asymmetrical networks with simulation of individual phases (instead of symmetrical components) and fault impedance
  • Calculation of short-circuit currents for 3-, 2- and 1-phase faults with and without earth connection
  • Calculation methods:?IEC 60909/VDE 0102 (2016, 2001, 1990),?IEC 61363 (1998),?IEEE C37 (2016, 1990),?G74,?GOST R 52735 (2007), 28249 (1993)
  • Calculation of short-circuit currents with initial load based on the load flow results
  • Determination of the maximum switch off time up to thermal destruction of lines and transformers
  • Visualization of the exceeding of permissible short circuit currents of equipment in the network graphic
