摘要
通过对发电机有功功率和无功功率关系、增加发电机有功功率对发电机运行状态的影响、励磁电流的调节对有功功率和无功功率影响等方面的分析入手,结合所录取的数据,分析1号机组发生功率波动的原因,得出励磁超调会造成机组功率的波动。同时,提出防范措施,避免再次发生类似现象。
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.
