Definitions

  • a fault current is an abnormal current in an electrical system resulting from a fault in the system, such as a short circuit.
  • a fault current may arise in a system due to any number of events or failures, such as power lines or other system components being damaged by severe weather (e.g. lightning strikes).
  • severe weather e.g. lightning strikes.
  • a large current a fault current
  • This surge of current is undesirable because of potential damage to the load, including the network itself, or equipment connected to the network.
  • FIG. 2 depicts an exemplary fault current limiter according to embodiments of the disclosure
  • FIG. 3 depicts an exemplary fault current limiter module of the fault current limiter of FIG. 2 according to embodiments of the disclosure
  • FIG. 4 depicts the exemplary fault current limiter of FIG. 2 with closed ends according to embodiments of the disclosure.
  • the power system 100 including a fault current limiter (FCL) 101, is implemented to include generation, transmission, and distribution networks generating and delivering power to various industrial, commercial, and/or residential electrical loads.
  • the FCL 101 may include a first current splitting device (CSD) 102 electrically coupled with a first fault current limiter module (FCLM) 104, and a second current spitting device (CSD) 106 electrically coupled with the CSD 102.
  • the FCL 101 may include a third CSD 107 in some embodiments.
  • one drawback with conventional fault current limiters built as a combined reactor is the build-up of inter-winding voltage.
  • an exemplary FCL includes a 33kV limiter (19.0kV to earth) with 75% limiting and 5: 1 transformer ratio to control the secondary current
  • the primary winding will see 19.0kV to earth and drop 14.3kV when limiting.
  • the secondary winding will also see 19kV to earth when the FCL switching modules are closed, yet 71.5kV (14.3kVx5) when the switching modules open.
  • FCLMs 260, 262 are electrically connected in series between the secondary winding 222 of the second CSD 206 and the secondary winding 238 of the third CSD 207.
  • FCLMs 256, 258, 260, and 262 are electrically connected in series along a path 226.
  • the primary winding 220 of the second CSD 206 is electrically connected in series with the primary winding 214 of the first CSD 206 and the primary winding 236 of the third CSD 207, for example, along the path 224.
