Embodiment Construction

[0036] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, which are to explain rather than limit the present invention.

[0037] The design concept of the vibration protection system for the hydro-generator set of the present invention is based on the vibration monitoring of the hydro-generator set. Experts formulate protection strategies according to the faults corresponding to the abnormal vibration of the hydro-generator set under various working conditions, and then according to the vibration The monitoring results match and invoke the adaptive protection strategy, thus forming a closed-loop system of vibration monitoring and vibration protection.

[0038] In this embodiment, the vibration protection system for the hydro-generator unit mainly includes an acquisition module for the original data of the hydro-generator unit, which is used to acquire process data, vibration data, equipment maint...

Abstract

The invention discloses a water-turbine generator set vibration protection method and system, and belongs to the technical field of water-turbine generator set monitoring. A mechanism model is constructed by adopting process data, vibration data, equipment maintenance data and patrol point detection data of the water-turbine generator set under different operation conditions, vibration analysis and judgment of the water-turbine generator set are realized by combining real-time data acquisition of the water-turbine generator set, and a protection strategy matched with the analysis and judgment result is called according to the analysis and judgment result, so that the water-turbine generator set is protected. The control command is generated, automatic adjustment control over the water-turbine generator set is achieved, and therefore a set of closed-loop protection measures is formed, and unit damage caused by abnormal vibration of the water-turbine generator set is avoided.

Description

technical field [0001] The invention belongs to the technical field of hydro-generator set monitoring, and in particular relates to a vibration protection method and system for a hydro-generator set. Background technique [0002] As the core equipment for energy conversion of hydropower stations, hydropower units are developing in the direction of giant, complex and intelligent, and the structure of units is becoming more and more complex, and the degree of integration is getting higher and higher. , The requirements for the safe and stable operation of hydro-generator units are getting higher and higher. [0003] Vibration is unavoidable during the operation of the hydro-generator unit. Excessive vibration or resonance will affect the safety of the entire unit. The hazards mainly include the formation and expansion of the fatigue damage zone caused by the rotation of the unit and the fixed part of the equipment, and the acceleration of the unit. Mutual wear of rotating par...
