Analysis of generator power swing |

Abstract: |
The generator power swing is analyzed from several aspects:the relationship between ge-nerator active power and reactive power,the influence of active power increase on generator opera-ting status and the influence of field current regulation on active and reactive powers. Combined with the data recorded,the conclusion is made:the excitation over-shoot causes generator power swing. Some countermeasures are provided. |
