摘　　要：为研究发电机单相短路时非故障相电压的谐波特性,以一台核电机组为例,采用场-路耦合法,建立了核电机组二维有限元模型以及单相短路外电路模型.通过对机组单相短路仿真,得到了故障后励磁电流及非故障相定子电压的谐波变化特征.In order to study the harmonic characteristics of the non-fault-phase voltage in a single phase short circuit generator,taking a nuclear power generator as an example,the two-dimensional finite element model and the single phase short circuit external circuit model are established by field circuit coupling method.Through the single phase short circuit simulation,the harmonic characteristics of excitation current and the non-fault-phase stator voltage after fault are obtained.
