Superconducting support for the grid

Comparison of efficiency



  • SuperVAR_fig4_OUT_
  • SuperVAR superconducting field winding and conventional stator
  • The major components of a rotating machine employing an HTS field winding
  • Comparison of efficiency
  • Damping of low frequency oscillations
  • Load angle swing owing to a 25 cycle fault
  • SuperVar contributes 6 pu current during the fault
  • Recovery of terminal voltage in about one second
