  • Patent number: 11334834
    Abstract: The system and method described herein relate to production of power from the wind farm that incorporate tunable power production forecasts for optimal wind farm performance, where the wind farm power production is controlled at least in part by the power production forecasts. The system and method use a tunable power forecasting model to generate tunable coefficients based on asymmetric loss function applied on actual power production data, along with tuning factor(s) that tune forecast towards under forecasting or over forecasting. The power production forecasts are generated using the tunable coefficients 34 and power characteristic features that are derived from actual power production data. The power production forecasts are monitored for any degradation, and a control action to regenerate the coefficients or retune the model is undertaken if degradation is observed.

  • Patent number: 8456048
    Abstract: A stator assembly includes a segmented stator having stator portions. Each stator portion includes stator laminations having stator windings, spacer plates having a portion embedded within the stator laminations, and structural plates having a portion embedded within the stator laminations. The portion of each of the spacer plates and each of the structural plates has notch-like structures that create openings to allow a cooling medium to flow between the notch-like structures to provide radial cooling of the stator windings. Connectors are provided to connect the stator portions of the segmented stator together.

  • Patent number: 8319389
    Abstract: An electric machine and stator assembly includes a segmented stator having stator portions. Each stator portion includes stator laminations, end plates arranged axially on opposing sides of the stator portion, and structural plates arranged interior to the end plates. Each of the support plates has a portion with notch-like structures that is embedded within the stator laminations. Stabilizing couple the end plates and the structural plates together. Connectors are provided to connect the stator portions together.
