中文摘要:

以新型直驱永磁风力发电机为研究对象,在完成采用XLPE高压电缆作为定子绕组的1.5MW/10.5kV内转子新型直驱永磁风力发电机电磁设计的基础上,在Ansoft Maxwell环境下建立发电机二维模型,对发电机各个工况下的电磁场进行有限元仿真与分析,包括静态空载、额定负载、不对称短路故障情况,对发电机永磁体在出线端突然三相短路时受冲击电流影响是否会发生局部失磁进行分析,验证新型永磁风力发电机电磁设计的可行性。结果表明,新型风力发电机与传统永磁风力发电机电磁场分布规律一致,且其额定电压高,绕组电流密度较小,额定负载与单相短路情况下永磁体磁场受电枢磁场影响较小,铜耗和铁耗也较小,同时在极端短路情况下永磁体局部不会出现永久性退磁,设计方案可行。

英文摘要:

The new type of direct drive permanent magnet wind turbine generator as the research object, in the completion of the XLPE high voltage cable is used as stator windings of the 1.5MW/10.5kV new type of direct drive permanent magnet rotor based on the electromagnetic design of wind turbine generator, a two-dimensional model in Ansoft under the environment of Maxwell, finite element simulation and analysis of electromagnetic field of the generator under various conditions, including static no load, rated load, asymmetric short circuit fault of generator, permanent magnet in the outlet end of sudden three-phase short circuit current affected by impact will occur partial demagnetization analysis, validate the feasibility of design scheme of new type of permanent magnetic wind power generator. The results show that, the traditional model of wind generator and permanent magnet wind generator electromagnetic field distribution, and the high rated voltage, current density, and the single phase short circuit rated load under the condition of the magnetic field of the permanent magnet armature magnetic field by the impact is small, the copper loss and iron loss is smaller, at the same time, in the extreme case of a short circuit will not be permanent magnet part also, the design scheme is feasible.
