摘　　要：本文采用差分法建立了转子瞬变电磁场及瞬变温度场计算机仿真的数学模型，并将其用于５０ＭＷ蒸发冷却汽轮发电机瞬态负序能力分析．对部分仿真结果与试验结果进行了比较．此外，通过仿真还获得了该发电机的最大瞬态负序能力．The computer-simulated mathematical model for rotor transient electromagnetic and temperature fields are found by finite difference method, and used for analyzing transient negative sequence capability of the 50 MW turbogenerator with evaporation cooling in this paper. The part of simulated results are compared with the experimental results. In addition, the maximum transient negative sequence capability is obtained by means of the simulation.
