  • Publication number: 20180335022
    Abstract: The present disclosure is directed to a tower assembly for a wind turbine having a tower flange that can accommodate foundations and/or nacelles of varying sizes. The tower assembly includes one or more tower sections having an integral tower flange that can be secured to a foundation, atop the tower section(s), and/or at a mid-height tower location. Further, the tower flange includes a substantially cylindrical wall defining an outer diameter and an inner diameter separated by an increased radial thickness. Thus, a radial offset is defined between the outer diameter of the tower flange and the corresponding tower component, i.e. the foundation, another tower section, or a yaw bearing. Accordingly, the larger radial thickness of the tower flange allows the flange to accommodate foundations or turbines of varying sizes with one common tower.

  • Patent number: 7845236
    Abstract: A fluid dynamic polymer-based contact sensor measures ambient pressure based on the resistivity changes across the sensor under different ambient pressures. The pressure sensor may applied to airfoil structures such as wind turbine blades without impacting the blade structure and fluid dynamic characteristics. The sensor may also be applied to fluid measurements. The pressure measurements are used to measure blade performance with high fidelity. The pressure measurements are transmitted to processing to determine blade characteristics and environment including flow separation, stagnation point, angle of attack, lift and drag and wind speed. Further processing of the pressure distribution may identify wind shear, up-flow and yaw error.

  • Patent number: 6408625
    Abstract: An electric power generation system is disclosed, which includes a back-up electric power generator driven by a four-cycle internal combustion engine. The engine includes a plurality of reciprocating cylinders each rotatably coupled to a crankshaft, which drives the electric power generator. The engine also includes a compressor along an intake pathway to deliver pressurized air to the cylinders and a turbine along an exhaust pathway to power the compressor when driven by exhaust discharged from the cylinders. The engine is prepared to accept a generator load by increasing boost pressure provided by the compressor. This increase is accomplished by skip-firing the cylinders in a selected pattern, retarding ignition timing for the cylinders, or a combination of these techniques. A unique skip-fueling control pattern is also disclosed.
