摘要
综述了发电机内部故障仿真分析方法及工程应用情况。阐述了适合于发电机主保护研究的内部故障仿真模型的基本要求,指出发电机内部故障仿真分析方法必须考虑定子实际绕组结构、具体故障位置以及内部非对称短路故障情况下气隙磁场谐波等因素的影响。展望了发电机内部故障仿真及相关领域的下一步研究工作。
The simulation methods and engineering application of generator internal fault analysis are summarized. The basic demands for the internal short circuit fault simulation model suitable for the main protection research of hydraulic generators are expatiated. In the process of internal fault simulation, several factors should be considered, such as the structure of stator windings, the exact fault spot, the gap harmonics under internal asymmetrical short circuit states, and so on. The future research of generator internal fault simulation and relative fields are prospected.
