Title: Optimal Design of a Fully Superconducting Machine for 10- MW Offshore Wind Turbines
{Fully superconducting (SC)machines hold immense promise for high-power-density and higher efficiency machine solutions for offshore wind turbine applications. In this paper, a 10MW air-core fully SC machine is designed for offshore wind turbine applications. This machine design is considered with inside armature coils and outside rotating field coils. In this topology, shield iron can be eliminated or reduced by replacing it with shield coils which contain the magnetic flux inside the machine. This machine is attractive for off-shore wind turbine application due to its high-power density and high efficiency compared to a conventional shield iron design. However, due to the introduction of additional shield coils, this topology uses relatively more amount of SC material than a conventional shield iron design. Therefore, a tradeoff between the shield coils and the shield iron is explored in this paper. In addition, machine designs with different pole-counts are investigated to identify the optimal pole-count design for a low-speed application. A detailed ac loss calculation is evaluated for the machine and required cryocooler power is evaluated to obtain the machine efficiency.  more » « less

    A significant challenge in the design of fully superconducting (SC) machines is managing ac losses in the SC armature. Recent developments in MgB2 superconducting conductors promise low ac loss conductors suitable for fully SC machines. This paper presents an optimized design targeting low losses and low weight for a 10-MW fully SC generator suitable for offshore wind turbine applications. An outer rotor air-core machine topology is investigated to optimize the design with low weight and low losses. An active shielding concept is used to minimize the pole count without adding excessive weight. This enables a reduction in the electrical frequency for a practical design by a factor of 4 to 5 over current designs, driving ac losses and active components weight lower by an order of magnitude. In this study, armature current is varied to control electrical and magnetic loading in order to minimize losses. A pole count study is conducted to identify the design space suitable for MW scale machines. A comparison is made between active shield, passive shield and a hybrid topology to address the benefits of an active shield for weight reduction. Results suggest that low-pole-count designs with MgB2 conductors will enable machines with less than 1 kW of ac losses.

    This paper demonstrates the concept of adaptive repurposing of a portion of a decommissioned Clipper C96 wind turbine blade as a pole in a power transmission line application. The current research program is aimed at creating a path towards sustainable repurposing of wind turbine blades after they are removed from service. The present work includes modelling and analysis of expected load cases as prescribed in ASCE 74 and NESC using simplified boundary conditions for tangent pole applications. Load cases involving extreme wind, concurrent ice and wind, extreme ice, differential ice, broken conductor, and broken shield have been analyzed and governing load cases for bending, shear, and torsion have been examined. Relative stiffnesses of different parts forming the wind blade’s cross section (i.e., shell, web, and spar cap) are determined. The corresponding stresses associated with each part under the governing loads are compared to allowable strength values which are determined from composite laminate theory and modelling of the known laminate structure of the E-Glass FRP material. Stresses and deflections obtained are compared with governing reliability-based design criteria and code requirements. The results of the structural analysis indicate that the wind blade can resist the expected loads with reasonable safety factors and that the expected deflections are within permissible limits. Recommendations are provided for detailing and modification of the wind blade for a power pole application in which crossarm and davit connections are highlighted, and foundation details are emphasized.

    Millions of tons of GFRP composites are expected to stockpile in the next 20-30 years from decommissioning wind turbine blades, which are made primarily of these materials. Responsible and attractive solutions are currently being studied by several research teams across Europe and the United States. The Re-Wind Network is one of these research teams that focuses on developing strategies and methodologies to transform the decommissioned wind blades into ready-to-use civil infrastructure (e.g., pedestrian bridge girders and power transmission poles). This paper reports on testing of a part of a full-sized power transmission pole prototype, made from a decommissioned GE37 wind turbine blade, and loaded in the gravity direction mimicking expected loads during its “new” lifetime. Full-scale connection testing is summarized and combined with the results of the test on the 5.5 m high full-size section of the prototype to obtain safety factors for various structural components under different expected load cases (these include gravity, wind, and ice loads). Structural Integrity of the various components of the power pole is studied to prove efficacy of the proposed second-life application of the decommissioned wind blade as a power transmission pole. Recommendations to improve the design for the planned future field full-blade prototyping are emphasized.

    Abstract As the effects of climate change become a greater threat, the need for a viable source of sustainable energy grows daily. Iron powder has been proposed as a potential alternative to conventional fossil fuels. Pulverized iron can be burned similarly to coal. Unlike coal, however, iron combustion does not create CO2 as a by-product. It also produces a negligible amount of NOx. Iron is also abundant in the Earth's crust, has a low explosion range, possesses a competitive energy density to hydrocarbons, and reacts well with oxygen. Finally, the iron oxide produced during combustion can be collected and reduced back to iron, creating a fully sustainable process. In this analysis, different power generation cycles were analyzed to maximize the energy and exergy efficiencies as well as the work output per unit mass of iron. It was found that the power cycle that maximized both the energy and exergy efficiencies as well as the work output per unit mass of input iron was a combined power cycle, where the topping cycle was a gas turbine cycle with one-stage compression and expansion and the bottoming cycle was a steam turbine cycle with two-stage expansion and reheat. This brought the theoretical energy efficiency to 59.87%, the theoretical exergy efficiency to 65.37%, and the theoretical work output per unit mass of iron to 4422 kJ/kg. The energy efficiency decreased to 56.81% when auxiliary devices were considered.

    A wind farm can provide reactive power at sub-transmission and transmission buses in order to support and improve voltage profiles. It is common for the reactive power capability of a wind farm to be evaluated as the sum of the individual turbine ratings. However, such an assessment does not take into account losses over the collector network, nor the voltage constraints imposed by the turbines and network. In contrast, the paper presents a method for determining the range of reactive power support that each turbine can provide whilst guaranteeing satisfaction of voltage constraints. This is achieved by constructing convex inner approximations of the non-convex set of admissible reactive power injections. We present theoretical analysis that supports the constraint satisfaction guarantees. An example illustrates the effectiveness of the algorithm and provides a comparison with a fully decentralized approach to controlling wind farm reactive power. Such approaches have the potential to improve the design and operation of wind farm collector networks, reducing the need for additional costly reactive power resources.
