Purpose:
To perform security-one-failure calculation optionally on a single node, in a cable or in a link or in an element.
General notation:
Protection ( Node( NodeName ), Distance, Closure, Rf, Xf, [Generation], [Load], [PV], [Wind], [Solar Time] )
Protection ( Cable( CableName ) , Distance, Closure, Rf, Xf, [Generation], [Load], [PV], [Wind], [Solar Time] )
Protection ( Line( CableName ) , Distance, Closure, Rf, Xf, [Generation], [Load], [PV], [Wind], [Solar Time] )
Distance in percent. Not applicable at node.
At the location of Closure, a text value should be entered or a text variable. The possibilities are:
| 'abc' | : symmetric closure |
| 'abc0' | : symmetrical closure with earth contact |
| 'a0' | : phase-to-earth closure |
| 'b0' | : phase-to-earth closure |
| 'c0' | : phase-to-earth closure |
| 'ab' | : phase-earth connection |
| 'ac' | : phase-terminal closure |
| 'bc' | : phase-terminal closure |
| 'ab0' | : phase-ground closure |
| 'ac0' | : phase-phase ground closure |
| 'bc0' | : phase-phase-earth closure |
After successful execution, the default Network.Result and Object.Result objects are equal to 'PROT' and 'NO' otherwise .
Examples:
Execute symmetric single-error calculation:
Protection ( Node ('MyNode') ,0 , 'abc', 0, 0 )
