摘　　要：利用ANSYS软件对汽轮发电机额定负载运行及谐波扰动时进行电磁场分析,并对二维有限元模型类型及原理进行了总结。最后以600MVA汽轮发电机为例,得出磁力线分布图和磁密分布图,证明仿真结果与理论相吻合,可为汽轮发电机的设计提供理论依据。The electromagnetic field of turbogenerator at load and disturbed harmonic is analyzed by use of the ANSYS software, the type and principle of two-dimensional finite-element model are summarized, and at last, taking the 600 MVA turbogenerator as the example, the magnetic figure and flux density distribution figure are drawn up. It is verified that the simulation result coincides with the theory, which can provide the theoretical basis for design of turbogenerator.
