Abstract: A power integrated system includes a gas storage unit, a gas driven generator, a power bus, a drilling rig, oil/gas production equipment, and a gas reformer. The gas storage unit is used for storing natural gas. The gas driven generator is used for generating electric power based on the stored natural gas. The power bus is used for receiving the electric power generated by the gas driven generator. The drilling rig is used for being driven by the electric power from the power bus. The oil/gas production equipment is used for being driven by the electric power from the power bus and for generating associated gas. The gas reformer is used for reforming the associated gas and supplying the reformed gas to the gas storage unit.

Abstract: The system includes at least one blade, a pitch command generator, a blade pitch system, a model store unit and a monitor unit. The pitch command generator is for generating at least one pitch command. The blade pitch system is for adjusting a pitch angle of the blade according to the pitch command and outputting an actual response representing an actual pitch condition of the blade in response to the pitch command. The model store unit is for receiving the pitch command and generating a desired response representing a desired pitch condition in response to the pitch command based on a nonlinear blade model. The monitor unit is for comparing a difference between the actual response and the desired response with a predetermined threshold and determining an operation status of the blade based at least in part on the difference. A method and a wind turbine are also provided.

Abstract translation: 该系统包括至少一个叶片，俯仰指令发生器，叶片俯仰系统，模型存储单元和监视器单元。 音调指令发生器用于产生至少一个音调命令。 叶片桨距系统用于根据桨距指令调节叶片的俯仰角，并响应于俯仰指令输出表示叶片的实际俯仰条件的实际响应。 模型存储单元用于接收音调命令并响应于基于非线性叶片模型的音调命令产生表示期望音调条件的期望响应。 监视器单元用于将实际响应和期望响应之间的差异与预定阈值进行比较，并且至少部分地基于差异来确定刀片的操作状态。 还提供了一种方法和风力涡轮机。
