Definitions

  • the electric network transmits electrical power to consumer devices that are usually called loads.
  • the electric power is generated in one or several generators that prime movers run.
  • the combination of one generator and one prime mover is usually called a generator set.
  • the prime mover can, for example, be a diesel engine or another type of a combustion engine.
  • the network has been protected in a normal way according to the IEC standards, for example.
  • the circuit breakers 9, 10, 23, 15, 16A, 16B, 16C, 16D, 16E etc. have been arranged to open selectively in fault situations to restrict the faulted part from the rest of the network in order that the rest of the network could operate at least satisfactorily.
  • the segment protection unit may comprise a delay function to adjust a moment or moments for transmitting the control signals.
  • the delay function can be utilized by using a delay unit, for example a delay circuit.
  • the delay function makes it possible to adjust the segment protection unit 19 for different electric networks, so it does not need to be manufactured for a certain network specifically.

Abstract

La présente invention concerne le système de protection d'un réseau électrique. Un court-circuit ou une surintensité dans une barre omnibus (5, 6, 7, 8) peut être détecté(e) si des courants sont mesurés à travers les interfaces de la barre omnibus et les données de mesure sont transmises à une unité de protection de segment (19). L'unité additionne les valeurs de courant mesurées. Si la somme dépasse une valeur de seuil, cela signifie qu'un court-circuit, ou qu'une surintensité existe dans le segment, et les disjoncteurs (9, 15, 23) dans les interfaces sont déclenchés.
