摘　　要：用额定电流时的主电抗和额定电压(突然短路饱和)时的电枢、励磁和阻尼绕组漏电抗、阻尼绕组谐波漏抗、励磁绕组对直轴阻尼绕组的漏抗,计算出隐极同步电机的超瞬变和瞬变电抗、时间常数以及突然短路电枢和励磁电流,与西门子(Siemens)公司提供的发电机超瞬变和瞬变电抗参数、时间常数、突然短路电流的计算机计算结果完全一致。The subtransient and transient reactance, time constants and sudden short-circuit armature and exciting current were calculated by means of the main reactance at the rated current and the leakage reactance of armature and exciting and damping winding, the harmonic leakage reactance of damping winding, the leakage reactance of the exciting winding to direct-axis damping winding at the rated voltage （at sudden short-circuit saturation）. They were as same as the computer calculation results of the subtransient and transient reactance, time constants and sudden short-circuit current of the generator supplied by Siemens company.
