摘要

为研究发电机单相短路时电磁转矩的变化特征，以一台核电机组为例，采用场-路耦合法，建立了仿真模型。通过对机组单机带额定负载运行时单相短路仿真，得到了故障前后气隙磁场以及电磁转矩的变化特征，指出故障后电磁转矩直流分量减小，同时产生了偶数次谐波分量。

Abstract:

In order to study the variation characteristics of electromagnetic torque of generator under single phase short circuit, taking a nuclear power generator as an example, The simulation model is established by field-circuit coupled method. Through the single phase short circuit simulation of generator with rated load, the variation characteristics of air gap magnetic field and electromagnetic torque before and after the fault are obtained, the harmonic components of electromagnetic torque before and after the fault is analyzed. The results show that the DC component of the electromagnetic torque decreases after the fault, and even harmonic components are generated.

Key words: Generator single phase short circuit field circuit coupling electromagnetic torque
