摘要:
为真实有效地反映实际并网运行的大型同步发电机发生定子绕组匝间短路故障时发电机定子电流及谐波电磁转矩等主要电气量的变化规律,采用场- 路- 网耦合时步有限元法对该问题进行了详细分析。以一台1 407 MVA 核电半速汽轮发电机为研究对象建立了场- 路- 网联合仿
真模型,在发电机并网带额定负载稳定运行条件下,对发电机定子绕组不同位置发生相同程度匝间短路故障进行了仿真,研究了大型发电机定子绕组匝间短路时故障位置对发电机机端三相电流、暂态基波电磁转矩、暂态二次谐波电磁转矩及稳态二次谐波电磁转矩的影响。为大型同步发电机定子绕组匝间短路故障诊断提供参考。
Abstract:
  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 was established,when the grid-connected generator runs at rated load and stable state. Then, the
stator winding inter-turn short circuit fault of generator was simulated in same fault degree and different fault position. The influences of generator stator winding inter-turn short circuit fault position on threephase current, transient fundamental electromagnetic torque, transient two harmonic electromagnetic torque and steady state two harmonic electromagnetic torque of generator were studied. The stator winding interturn short circuit fault diagnosis in big synchronous generator is provided by the research.
