水轮发电机组在线监测中的瀑布分析技术研究

随着在线监测技术的普及,越来越多的水电厂安装了机组在线监测系统,但除了显示简单的机组运行参数数值外,如何通过在线监测系统得到更多有效的机组健康信息,一直是研究中的课题。本文主要介绍了在水轮发电机组的在线监测中,如何对实时数据进行瀑布分析,得到机组运行过程中测量信号的频率成分随时间或工况变化的规律,有效解决了实时监测中显示数据过于独立、难以发现机组运行特性和隐含故障的问题。

Waterfall analysis technology rcsearch of hydropower unit on-line monitoring system

With the popularization of monitoring technology,more and more hydyopower stations are equipped with the unit on-line monitoring system.But apart from the simple operating parameters,how to get more effective information by the on-line monitoring system has been a question.This paper presents how to make waterfull analysis for the real-time data in the unit on-line monitoring ststem and get the operating characteristics with the change of condition or time,then,provides an effective way to overcome the shor...
