  • Bang-Bang Controller and Control Method For Variable Speed Wind Turbines During Abnormal Frequency Conditions
    Publication number: 20110012352
    Abstract: 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.

  • Frequency-Responsive Wind Turbine Output Control
    Publication number: 20110001318
    Abstract: 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. The controller may include a monitor (52) configured to monitor a correlation between a deviation from a grid frequency and a wind power change. The controller may be configured to adjust a response of the electrical output power based on the monitored correlation. The electrical output power response may be configured to meet a grid frequency regulation notwithstanding of random occurrences of wind power changes.

  • Superconducting coil support structures
    Patent number: 7825551
    Abstract: 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).
