摘　　要：介绍了因自动励磁调节器 (AVR)故障 ,过电压、过励磁保护设置不完善 ,以及整定欠合理而导致发电机、主变压器严重过电压和过励磁的实例 ;对微机型 AVR的过励磁或过电压、励磁过电流、低励磁限制和保护整定计算进行了探讨 ;提出了为完善以上保护功能 ,确保发电机、主变压器的安全运行而改进过励磁和过电压保护的措施。The paper presents some examples that generator and main transformers undergo serious over-voltage and over- excitation due to AVR failure, imperfect configuration and irrationality of setting calculation of relevant protection. Discussed in detail are over-excitation and over-voltage, over current, low excitation and the setting calculation of AVR protection. In order to assure generator and main transformers to run safely,feasible measures to improve and consummate the function of protection are put forward.
