Abstract

The invention discloses a hydroelectric generating unit vibration state region monitoring method based on real-time online monitoring. The method includes on the basis of the traditional hydroelectric generating unit vibration online monitoring, adopting a hydroelectric generating unit vibration wave recording analysis device to acquire and analyze original sample data of vibration monitoring points of the unit, and establishing a feature data storing history storing database of the vibration monitoring points; on the basis of historical feature data statistic analysis, the real-time unit vibration state region is determined comprehensively, and the real-time alarm information display and historical alarm information statistic and querying features are provided according to the determination results. The method has the advantages of high function comprehension, high result accuracy and convenience and easiness for usage.

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 complicated. 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 statis...
