摘　　要：针对国民经济的发展对供电质量要求越来越高的现状,设计了一套在线状态监测系统对水力发电机组进行实时在线状态监测,同时研究了信号处理方法,将小波分析技术运用于机组振动信号的分析处理中,并通过实例验证了系统的可行性和适用性。The development of the national economy places higher and higher requirements for the electricity supply. In accordance with this requirement, it is necessary to monitor the working states of these power generators. This paper designs a system to monitor the states of hydraulic generators and studied the method of fault diagnosis, which is accuracy and effectiveness proved by the experimental data.
