摘　　要：回顾了发电机内部短路研究的发展状况，阐述了大型汽轮和水轮发电机内部故障研究的最新进展和新问题。认为在电机内部故障分析中必须突破理想电机的限制；多回路分析可以较好地考虑气隙磁场空间谐波的影响，成为分析电机内部故障的有效手段。最后，从实际应用出发，探讨了内部故障计算的简化方法，强调简化时必须注意物理概念的合理性，并应得到实验验证。The development of research on internal short circuit of generator is reviewed.New approach for research on internal faults of large turbogenerator and hydra generator is expounded .In the analysis of internal faults of electric machine, the limits on the ideal electric machine have to be broken. The multiloop analysis has became efficient method of research on internal faults of electric machine, because this method may consider better the effect of the space harmonics of air gap magnetic field in the analysis of internal faults. Finally, from the point of practical use, the simplified methods for calculation of internal faults are studied. In the simplification, the reasonableness of physical concept has to be emphasized, and the experimental tests have to be given.
