| 摘 要： | 发电机失磁时会对系统及发电机本身造成一定的破坏,目前国内外失磁保护判据都存在一些问题。文中通过对发电机发生失磁故障及发电机—变压器侧发生三相短路故障时各电气量的变化进行仿真、比较,深入研究了失磁的动态过程,提出了一种更合适的发电机失磁保护方案。

| Abstract: | There are some problems in the aspect of determination of the criteria of excitation-loss protection at home and abroad. Simulation and comparison are made on the variations of all the electric parameters when the failures of the excitation-loss and the three-phase short-circuit at the side of generator-transformer occur; in which the dynamic process of the excitation-loss is deeply studied and then a excitation-loss protection plan more suitable for generator concerned is put forward herein as well. |
