摘要：

In order to truly and effectively reflect the stator current and harmonic electromagnetic torque variation laws of grid connected synchronous generator with stator winding inter-turn short circuit fault, the field-circuit-network coupling finite element method was adopted to analyze this problem in detail. Taking a 1 407 MVA nuclear power half speed turbine generator as an example, the model of field-circuit-network coupling is established, when the grid-connected generator runs at rated load and stable state. Then, the stator winding inter-turn short circuit fault of generator is simulated in same fault degree and different fault position. The influences of generator stator winding inter-turn short circuit fault position on three-phase current, transient fundamental electromagnetic torque, transient two harmonic electromagnetic torque and steady state two harmonic electromagnetic torque of generator are all studied. The stator winding inter-turn short circuit fault diagnosis in big synchronous generator is provided by the research. © 2019, Harbin University of Science and Technology Publication.
