Abstract

A method for regional monitoring of the vibration state of a hydro-generator set based on real-time online monitoring. Based on the traditional on-line vibration monitoring of a hydro-generator set, the method uses a hydro-generator vibration recording analysis device to collect and analyze each vibration monitoring point of the unit. At the same time, the characteristic data storage history library of each vibration monitoring point is established; on the basis of statistical analysis of historical characteristic data, the comprehensive judgment of the real-time vibration state area of ​​the unit is realized, and the judgment result is provided with real-time early warning information display and history Early warning information statistical query function. The method has the characteristics of strong comprehensive functions, high accuracy of results, and convenience and ease of use.

Description

technical field [0001] The invention relates to the field of industrial control, in particular to a method for monitoring the vibration state area of ​​a hydroelectric generating set. Background technique [0002] For a long time, in hydroelectric generating units, mechanical vibration has been a key factor that threatens the safe production and operation of hydroelectric generating units. The vibration of a hydroelectric generator set is often caused by the joint action of mechanical, electrical, and hydraulic factors, and the vibration mechanism is relatively complex. The vibration and swing of the unit will also be caused by design, installation, operation and other reasons, which cannot be completely avoided and eliminated. In short, general vibration will not cause harm to the unit, but if it exceeds the allowable value seriously, especially for a long time, it will have a serious impact on the unit. [0003] At the same time, according to relevant industry statistics...
