Abstract: A superconducting magnet apparatus includes a plurality of superconducting magnet coil sections connected in series and housed within a cryogenically cooled, vacuum container. A power source generates a current. A first lead is electrically connected to the superconducting magnet coil sections. A second lead is enclosed entirely within the vacuum container. The second lead has a first section and a second section, and the first section is electrically connected to the power source. The second section is electrically connected to the first lead, and rigidly connected to a linear displacement device enclosed entirely within the vacuum container. The linear displacement device linearly displaces the second section relative to the first section, so that the first section contacts the second section thereby electrically connecting the first and second sections, or by creating a gap between the first section and second section thereby electrically disconnecting the first section from the second section.

Abstract: A wind turbine power generating system and method includes a tower, a hub, a plurality of blades connected to the hub, and a rotor connected to the hub. A superconducting generator is coupled to the rotor and includes a plurality of superconductive coils. A nacelle is mounted atop the tower, with the superconducting generator housed within the nacelle. An automatic ramp-down system is configured with the superconducting coils and includes an automatically activated energy dump circuit for current withdrawn from the superconductive coils in a ramp-down process prior to a quench. The energy dump circuit includes one or more heat dissipating loads, wherein each of the heat dissipating loads is mounted in thermal communication with one of the tower or the nacelle that act a thermal heat sink for dispersing heat from the loads.
