Levelized Cost of Energy Comparison Between Permanent Magnet and Superconducting Wind Generators for Various Nominal Power

Optimization and comparison of modern offshore wind turbine generators using GeneratorSE 2.0

“…The armature phase resistance is then computed from the total length of armature coils per phase L cus = S mNcla and conductor cross section using equation (3). In computing the lengths for the field coil, the wire length for one racetrack is determined and multiplied by the number of turns, l sc = N sc (2l s + π(a m + w sc )).…”

“…To address this problem, wind turbine manufacturers are investing in advanced generator technologies, including the use of high-field reduced rare earth or rareearth-free permanent magnet synchronous generators (PMSG) enabled by unique flux-enhancing topologies and superconductors [2]. Prior studies of these technologies have been restricted to conceptual designs or designs based on rareearth-rich permanent magnets, or have precluded the economic feasibility of superconducting technology due to its high costs to commercialization [3], [4]. These comparative studies have also largely focused on high-temperature superconducting generators, ignoring low-temperature options.…”
