| 摘 要： | 本文运用电机和电磁场理论建立了发电机运行特性的数学模型,给出了有限元求解二维电磁场的方法。为满足运行特性的计算要求,将电机内电磁场的有限元计算与外部电路相结合,计算出了不同工况下超高压发电机的特性曲线,包括短路特性、空载特性、调整特性和外特性。通过和实验结果的对比,证明了数值仿真的正确性,从而为超高压发电机的实际应用提供了参考依据。

| Abstract: | In this paper, operational characteristics mathematical model of generator is built based on electric machines and electromagnetic field theory, and the method of solving the two-dimension electromagnetic field with FEM is given. To satisfy the calculation demand of operation characteristic, the method for the electromagnetic field and external circuit are combined. And by calculating, the operation curves for Powerformer under different conditions are obtained, including short-circuit characteristic, open-circuit characteristic, regulation characteristic and external characteristic. |
