| 摘 要： | 大中型火力发电机组励磁系统运行时,如果进行励磁调节器(AVR)与备用励磁切换操作,发电机组瞬间会出现很大的无功冲击.为了实现发电机组主备励之间无扰动切换,在建立新的数学模型的基础上,提出了超前补偿法.经过珠江发电厂1号和3号机组的实际应用,证明了超前补偿法有效地解决了机组的无功冲击.

| Abstract: | There exists momentary reactive power percussion when on-line-switching is completed between AVR and reserve excitation in excitation system' of large-medium-scale fossil fuel generator unit. In order to realize on-line-switching without any reactive power percussion between AVR and reserve excitation, this paper establishes a new mathematical model of excitation system and provides advance-retrieval method. The practical application of the method to No 1 and No 3 unit of Zhujiang Power Plant in China indicates that the advance-retrieval method solves reactive power percussion of generator units successfully. |
