AI Technical Summary

Technical Problem

Hydropower station pressure pipelines are susceptible to creep, fatigue and corrosion in high-pressure environments, resulting in reduced safety. Water hits may lead to pipeline bursts, affecting normal operation and bringing economic losses and safety hazards.

Method used

By monitoring the flow and pressure data of the water in and out of the hydropower station, the fault location is determined using interval sensors, and the fault point is calculated by combining the flow and pressure data to achieve rapid fault positioning and type identification.

Benefits of technology

It improves the accuracy and efficiency of pipeline fault detection in hydropower stations, reduces the time and cost of fault search, and reduces the energy consumption and data processing volume of sensors.

Abstract

The invention provides a hydropower station pipeline fault alarm method and device. The hydropower station pipeline fault alarm method comprises the steps that first flow data, first pressure data, second flow data and second pressure data of a target hydropower station are acquired; when the difference value between the first flow data and the second flow data is greater than a first threshold value and the difference value between the first pressure data and the second pressure data is greater than a second threshold value, acquiring interval sensing data; and determining a fault position based on the interval sensing data, the first flow data, the first pressure data, the second flow data and the second pressure data, and generating an alarm based on the fault position. The running state of the system can be evaluated more comprehensively by monitoring the two key parameters of the flow and the pressure at the same time, meanwhile, the interval sensor of the target hydropower station is started under the condition that the fault is determined, the fault area can be quickly locked through the interval sensor, the time and cost needed for finding the problem are greatly reduced, and the efficiency is improved. And meanwhile, the energy consumption and the data processing amount of the sensor can be reduced in a normal state.
