摘要
本文针对新型高压发电机Powerformer的参数计算问题,运用有限元法计算了Powerformer槽漏抗、端部漏抗和电枢反应电抗,并与传统电机设计方法的计算结果进行了比较。结果表明Powerformer的电枢反应电抗可以采用传统电机设计方法计算,半圆形槽漏抗可以根据传统圆形槽和矩形槽漏抗的计算方法来确定,端部漏抗适宜采用有限元方法计算。
To calculate the parameters of eowertormer, a new type of high voltage generator, the finite element method is proposed in, this paper. The slot leakage reactance, end region leakage reactance and armature reaction reactance of Powerformer are calculated with FEM and compared with the results calculated by traditional electrical machine design method. The result shows that armature reaction reactance can be calculated by traditional electrical machine design method; leakage reactance of semicircular slot can be determined by round-shape slot and rectangle slot leakage reactance; and FEM is more suitable for end region leakage reactance calculation.
