摘　　要：发电机作为发电厂的核心部件,对于电力系统的稳定运行起到关键作用,但是发电机存在的局部放电现象会对其正常运行产生一定程度的影响,因此对发电机局部放电现象进行实时监测意义重大。将高频耦合法引入发电机局部放电的实时监测中,设计一种全新的基于高频耦合法的高频脉冲信号实时监测系统。通过运用实例分析,所设计的局部放电实时监测系统数据变化范围正常,能够有效监测发电机局部放电现象,并记录和分析数据,为后期发电机的保养、维护工作提供可靠的数据支持。As the core component of power plants,generators play a key role in the stable operation of power systems.However,the partial discharge phenomenon of the generator will have a certain degree of impact on its normal operation,so it is of great significance to monitor the partial discharge phenomenon of the generator in real time.The high-frequency coupling method is introduced into the real-time monitoring of generator partial discharge,and a novel high-frequency pulse signal real-time monitoring system based on the high-frequency coupling method is designed.Through case analysis,the designed partial discharge real-time monitoring system has a normal data change range,which can effectively monitor the partial discharge phenomenon of generators,record and analyze data,and provide reliable data support for the maintenance and maintenance of generators in the later stage.
