Abstract: A method for monitoring at least one rotor blade of a wind turbine includes implementing, via a controller, a control scheme for monitoring blade damage of the at least one rotor blade. The control scheme includes monitoring at least one electrical condition of a pitch system of the wind turbine. The method also includes converting the electrical condition(s) of the pitch system into a frequency domain. Further, the method includes determining one or more peaks of the frequency domain around a frequency component related to a natural frequency of the rotor blade. Moreover, the method includes determining a frequency deviation between the one or more peaks of the frequency domain and the frequency component related to the natural frequency of the rotor blade. As such, a frequency deviation outside of a predetermined frequency range is indicative of a rotor blade anomaly. Thus, the method includes implementing a control action when the frequency deviation is outside of the predetermined frequency range.

Abstract: A method of manufacturing a tower structure includes providing an additive printing device having at least one printer head atop a support surface. The method also includes positioning a pre-fabricated component adjacent to the support surface. The pre-fabricated component is constructed of a composite material reinforced with a plurality of reinforcement members. Further, portions of the plurality of reinforcement members protrude from the composite material. Moreover, the method includes printing and depositing, via the at least one printer head, a cementitious material onto the support surface to build up the tower structure layer by layer around the pre-fabricated component. Thus, the portions of the plurality of reinforcement members that protrude from the composite material reinforce the cementitious material around the pre-fabricated component.

Abstract: A method for manufacturing a tower structure of a wind turbine includes printing, via an additive printing device, the tower structure of the wind turbine of a cementitious material. During printing, the method includes embedding one or more reinforcement sensing elements at least partially within the cementitious material at one or more locations. Thus, the reinforcement sensing element(s) are configured for sensing structural health of the tower structure, sensing temperature of the cementitious material, heating to control cure time of the cementitious material, and/or reinforcing the cementitious material. In addition, the method includes curing the cementitious material so as to form the tower structure.

Abstract: A method for manufacturing a tower structure of a wind turbine includes printing, via an additive printing device, a plurality of concentric sections of the tower structure of the wind turbine. The concentric sections may be printed simultaneously from concrete, may include tensioning cables or other structural supports, and may define other support flanges or overhangs. After curing, the method may include raising an inner section of the plurality of concentric sections to a top of an adjacent outer section and joining the two sections. This process may be repeated to telescope the concentric sections and raise the tower structure.

Abstract: Systems and methods of wind power generation in electrical power systems are described. According to one aspect, a wind turbine system can include a down tower portion having a main transformer configured to transform medium voltage power to another voltage power, a tower portion having one or more medium voltage cables configured to transmit medium voltage power, and, a nacelle portion. The nacelle portion can include a generator comprising a stator and a rotor. The stator may be connected to one or more medium voltage cables via a stator power path. The nacelle portion also includes a power converter coupled to the rotor of the generator, and, a step-up transformer coupled to the power converter and the one or more medium voltage cables. The step-up transformer can be configured to step-up low voltage power to medium voltage power.
