New type of direct drive permanent magnet wind turbine generator of electromagnetic field numerical analysis
摘要
Abstract
The new type of direct drive permanent magnet wind turbine generator as the research object , in the com-pletion of the XLPE high voltage cable which is used as stator windings of the 1.5 MW/10.5 kV 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 , the 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 , and permanent magnet in the outlet end of sudden three-phase short circuit current affected by impact will occur par-tial demagnetization analysis , which validate the feasibility of design scheme of new type of permanent magnetic wind power generator .The results show that , the electromagnetic field distribution of the traditional model of wind generator is in.accordance with the new permanent magnet wind generator , and the high rated voltage , current density , and the single phase short circuit rated load under the condition of the magnetic field , the permanent magnet armature magnet-ic field by the impact is small , and the copper loss and iron loss is smaller , at the same time , in the extreme case of a short circuit , the partial permanent magnet will not occur the permanent magnetic demagnetization .The result shows that the design scheme is feasible .关键词
