Abstract: A system and method are provided for manufacturing a tower structure. Accordingly, one or more layers of a wall element are deposited with a printhead assembly. At least one recess is defined in the wall element. The recess(es) has a single, circumferential opening positioned along an inner reference curve or an outer reference curve of the wall element. The recess(es) also has a depth which extends in a radial direction and intersects a midline reference curve. A reinforcing element is placed entirely within the recess(es) at the midline reference curve.

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 rotor blade for a wind turbine includes an internal support structure extending span-wise from a blade root to a blade tip. A plurality of ribs are fixed to and spaced along the internal support structure, with each rib extending in a generally chord-wise direction and having a generally aerodynamic blade contour. A plurality of chord-wise oriented fabric strips are affixed to the ribs in a tensioned state, wherein the fabric strips define an aerodynamic outer skin of the rotor blade.

Abstract: A tower structure particularly suited for a wind turbine includes a lower tower section formed of concrete and an upper tower section formed of steel. A transition system connects the upper tower section to the lower tower section, the transition system including a concrete component having a tubular wall with a base portion fixed on the lower tower section and a head portion connected to the upper tower section. The head portion extends radially outward beyond the upper tower section. A plurality of first tensioning tendons extend longitudinally at least partially through the tubular wall and are anchored to the concrete component at a top face of the head portion at locations radially outward of the upper tower section.

Abstract: A method and system of additively-manufacturing a structure having a reinforced access opening includes printing, via an additive printing device having at least one printer head, a portion of the structure adjacent to a support surface. The portion of the structure is printed of a cementitious material, and the printed portion of the structure defines an access opening for the structure. Moreover, the method includes providing a void of the cementitious material at a top boundary of the access opening, placing one or more reinforcement members in the void such that the one or more reinforcement members extend across the void, and continuing to print the printed portion of the structure around the void to build up the structure. Thus, the method also includes backfilling the void with a backfill material to incorporate the one or more reinforcement members within the void into the printed portion of the 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.
