主 题：High‐temperature superconducting bulk Ocean energy Wave energy converter Linear power generator Dual translator
摘 要：We show a conceptual structure for a wave energy converter,which features a direct‐drive linear power generator with REBaCuO high‐temperature superconducting(HTS)bulk field poles and driven by a heaving buoy.A dual translator power generation system of the proposed concept structure is a linear generator in which both the HTS bulks and armature copper coils move in opposite directions simultaneously.A performance analysis of our linear generator was conducted using a finite‐element electromagnetic field analysis *** results of the analysis were compared between the HTS dual translator linear power generator and the HTS single translator linear power *** maximum electromagnetic force and the average output power of the HTS dual translator are around 5%and 11%higher than that of the HTS single *** further present the results of the analysis regarding the influence of reducing the stroke length of the linear generator translator on the output power,where the output power for the HTS dual translator system increased up to a factor of two,in comparison to the HTS single translator counterpart,for the same reduction of stroke length.
