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.

Abstract: A rotor blade for a wind turbine includes an internal support structure including a plurality of fixed, spaced support members extending in a chord-wise and span-wise direction and defining a generally aerodynamic contour of the rotor blade. A plurality of the support members have an outer surface with a longitudinally extending slot defined therein. A plurality of fabric strips are attached over the internal support structure in a tensioned state and define an aerodynamic outer skin. The fabric strips extend over and are attached to the support members with a longitudinally extending insert member that presses the fabric strips into the slot and lockingly engages within the slot.

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.
