| 摘 要： | 为了对汽轮发电机定子绕组内部故障进行快速保护以减轻造成的损害 ,必须对各种内部故障瞬态有全面的分析。论文用气隙磁导的概念和谐波分析的方法计算了汽轮发电机内部故障时的实际回路参数 ,并简化考虑了实心转子的涡流效应。用多回路方法仿真研究了定子绕组的各种内部故障瞬态。通过对一台模拟发电机的内部短路试验与仿真结果的对比 ,证明了该文提出的多回路模型和方法的正确 ,为研究汽轮发电机内部故障瞬态及其保护方案提供了理论基础。

| Abstract: | All transients should be analyzed to protect rapidly turbogenerators from damage due to inner faults in stator windings. The air gap permeance concept and harmonic analysis method were used to calculate the parameters for turbogenerators with armature asymmetries and the eddy current effect in the turbogenerator solid rotor was considered. The transients are simulated using the multi loop method. The method was verified experimentally. A theoretical basis for studying the transients due to inner faults in turbogenerators and its protection schemes were given. |
