摘要
针对一种新兴高压发电机电力发生器定子端部磁场与漏抗计算问题,利用有限元分析软件ANSYS,建立了简化的电力发生器定子端部三维模型,进行了端部磁场和漏抗在有铁心与无铁心两种情况下的计算,并对两组计算结果与设计值进行了对比分析。结果表明,传统算法所计算的漏抗值波动大,而采用有限元分析法所得计算结果更为确定。
In this paper,against the stator end region of Powerformer, a new kind of high-voltage generator, simplified three dimension stator end region is established with the help of ANSYS. The end region magnetic field and leakage reactance is calculated respectively under two situations. Then two results are compared with design value and analyzed. The results prove that the reactance value solved by traditional method is not certain. The reactance value solved by FEM is more certain and reliable.
