| 摘 要： | 从灭磁时间和灭磁时反电压出发,讨论了水轮发电机灭磁用非线性电阻ZnO、SiC的选择。介绍了三峡水电厂700 MW VGS发电机带负荷突然三相短路后,用非线性电阻在不同灭磁反压下的灭磁仿真结果,分析了不同灭磁动作瞬刻下各部分的磁能吸收情况,并对灭磁时间的定义提出了建议。

| Abstract: | In point of de-excitation time and inverse voltage during de-excitation,the selection of non-linear resistors such as ZnO and SiC for de-excitation for hydraulic generators is discussed.The de-excitation simulation results for abrupt three-phase short-circuit of the 700 MW VGS hydraulic generator of the Three Gorges Hydropower Plant with non-linear resistors under different inverse voltages are given.The absorbed magnetic energy at different de-excitation moments is analyzed,and a definition of de-excitation time is proposed. |
