摘　　要：针对传统断线故障保护方法在实际应用中存在完成保护时间较长,无法快速恢复发电机励磁调节器稳定运行问题,研究发电机励磁调节器PT电压回路断线保护方法。分析了发电机励磁调节器故障原因,通过获取PT电压回路断线故障电流特征,配合其他保护完成断线故障保护,提出一种新的断线故障保护方法。通过对比实验进一步验证,与传统保护方法相比,新的断线保护方法能够实现对断线故障的快速保护,防止由于断线故障对发电机励磁调节器PT电压回路造成的影响,确保发电机励磁调节器能够安全、稳定运行。In view of the problem that the traditional line break fault protection method has a long time to complete the protection and can not quickly restore the stable operation of the generator excitation regulator,the line break protection method of the PT voltage circuit of the generator excitation regulator is studied.Firstly,the fault reason of generator excitation regulator is analyzed,and then a new method of line break fault protection is proposed by acquiring the current characteristics of Pt voltage circuit line break fault and cooperating with other protections to complete line break fault protection.Compared with the traditional protection method,the new method can realize the fast protection of the broken line fault,prevent the influence of the broken line fault on the PT voltage circuit of the generator excitation regulator,and ensure the safe and stable operation of the generator excitation regulator.
