AI Technical Summary

Technical Problem

The existing power station gate opening monitoring methods fail to fully consider the dynamic changes of the gate in actual operation, such as the water level change interval, power generation task volume and the life status of the gate, resulting in misjudgment of the monitoring results.

Method used

By collecting the design standards and life status information of the gate, obtaining the water level change interval and power generation task volume, determining the expected operating opening degree, using the gate risk opening database for quantitative calculation, obtaining the degree of risk abnormality of the gate, and visually displaying it.

Benefits of technology

It improves the accuracy and real-timeness of gate opening monitoring, can more comprehensively reflect the actual operating status of gates, reduce misjudgments, and improves the safety and efficiency of hydropower stations.

Abstract

The present invention relates to the technical field of hydropower station operation and maintenance management, and in particular to a method and system for monitoring the gate opening of a power station applied to hydropower dispatching operations, which improves the safety, stability and efficiency of the operation of the hydropower station; the method comprises: collecting design standard information and life status information of each gate of the hydropower station; obtaining the water level change interval within a set time and the power generation task of the hydropower station; determining the expected operating opening of each gate within the set time based on the power generation task and the design standard information of each gate; for each gate, using the gate life status information and the water level change interval as double-limit positioning conditions, positioning in a pre-built gate risk opening database to obtain the gate risk opening interval; performing risk quantification calculation on the expected operating opening and the gate risk opening interval corresponding to the same gate, and obtaining the risk abnormality degree corresponding to the gate.
