摘要： Support structures (100) for attaching superconducting conductors (106) to a rotor (50) of an electrical machine (10). The support structures (100) are mechanically configured to transfer loads exerted on the superconducting conductors (106) during both normal and transient operation of the rotor (50). The mechanical configuration and material of the support structures (100) further present a thermal path that is longer than the physical distance between the superconducting conductors (106) and the rotor (50) thereby minimizing heat flow from the warm rotor (50) to the cold superconducting conductors (106).

摘要： A wind farm (10) may include a plurality of variable speed wind turbines (12, 14, 16). A centralized controller (50) may be configured to selectively adjust a respective electrical output power from each of the wind turbines at least during an underfrequency condition. The controller may include a monitor (52) configured to monitor a grid frequency value relative to at least a first threshold value. A deviation of the grid frequency value beyond the first threshold value is indicative of the underfrequency condition. The controller further includes a control unit (54) configured to effect a step response to the electrical output power of the wind turbine in a direction selected to counteract the underfrequency condition.
