“…However, the usage amount of the SC coil for IRAST is nearly two times of the IRIST. The cryogenic power is proportional to the AC loss, as deduced from (6), which means the cryogenic power for IRIST is also smaller. In this paper, SCPM generators with two different topologies are designed, optimized and compared.…”

This paper mainly focuses on the comparison of electromagnetic performance of the superconducting permanent magnet (SCPM) generators with two different topologies. The torque capabilities of the two generators are first investigated. The peak torque is largely restricted by the material characteristics of the SC and the permanent magnet (PM). It turns out that the SCPM generators with iron-cored rotor and iron-cored stator topology (IRIST) is superior to the one with iron-cored rotor and air-cored stator topology (IRAST) in terms of torque capability. Furthermore, the flux density, line electromotive force (EMF), torque and its torque ripple, and the efficiency of the designed generators are evaluated by using numerical model. The simulation results confirm that IRIST has higher output torque and efficiency with the penalty of higher harmonics and torque ripples.  Index Terms-Finite element method (FEM); superconducting permanent magnet wind power generator; topology; comparison

In order to meet the higher requirements (i.e. large scale, high reliability and direct drive) of generators used for offshore wind turbine, a novel direct drive module dual stator brushless doubly-fed generator (DSBDFG) with cage-barrier rotor having many outstanding merits is proposed in this paper. The fundamental structure, operation principle and power flow are presented. The electromagnetic design methods of the proposed generator including power distribution of inner and outer machines, the relationship of pole number, slot number and module number, and winding design are thoroughly investigated. In order to solve the problems in structure brought by module design and reduce the weight as much as possible, a mechanical construction applied for module DSBDFG is proposed. Finally, the correctness of the proposed electromagnetic design method and the stability of the proposed mechanical construction are verified based on finite element analysis respectively.

“…Luckily, the use of superconducting (SC) materials in low speed wind generators named as superconducting direct-drive synchronous generator (SCDDG), emerges as a promising solution for achieving reliable, lightweight, and higher power level (10 MW or beyond) wind turbine [15,16]. At present, lots of research on SCDDGs are being actively carried out [17][18][19][20][21][22][23][24][25][26][27]. In [18], various topologies of SCDDGs were reviewed.…”

Bu çalışmada, sırasıyla tek kutuplu uyarma ve çift kutuplu uyarma olarak belirlenmek olan, HTS bobininin iki çeşit yerleştirme stratejisi önerilmektedir. Üstelik, HTS bobininin uyarma çalışma noktalarını belirlemek için bu çalışmada HTS kablolarının tüketimi ile tek/çift kutuplu HTS-DSDDG'lerin hacmi arasındaki ilişki kantitatif olarak araştırılmaktadır. HTS bobinlerinin farklı yerleştirme stratejileri, uyarma çalışma noktalarının, jeneratör boyutlarının ve HTS kabloları tüketiminin farklarına neden olacağından dolayı tek ile çift kutuplu HTS-DSDDG elektromanyetik verimi, ağırlığı ve malzeme masrafı açısından karşılaştırılmaktadır. Sonuç olarak, çift kutuplu HTS-DSDDG'nin tek kutuplu HTS-DSDDG'den daha hafif ve daha düşük maliyetli olduğu çıkarılmaktadır.Anahtar Kelimeler: Büyük ölçekli rüzgar jeneratörü, HTS, çift stator, Çift statorlu, uyarma çalışma noktası. ABSTRACTThe high temperature superconducting (HTS) exciting double stator direct-drive wind generator (HTS-DSDDG) is a promising approach for offshore wind generation, due to the fact that double-stator structure is employed to simultaneously realize stationary seal of the cooling system and brushless of current transfer. In this paper, two kinds of placement strategies of HTS coils are proposed, denoted as single-polarity excitation and double-polarity excitation, respectively. Furthermore, the relationship between the consumption of HTS wires and the volume of the single-/double-polarity HTS-DSDDGs is quantitatively investigated to determine the excitation operating points of HTS coils. Since the different placement strategies of HTS coils will lead to differences of the excitation operating points, as well as differences of generator size and HTS wires consumption, the single-/double-polarity HTS-DSDDGs are compared in terms of the electromagnetic performance, the weight and the material cost. Finally, the conclusion is drawn that the 10 MW double-polarity HTS-DSDDG is lighter and lower cost than the single-polarity one.
