Hydroelectric generating set guide vane water leakage analysis method and system and storable medium

Abstract

The invention discloses a hydroelectric generating set guide vane water leakage analysis method and system and a storable medium. The method comprises the following steps that S1, the working door state, the guide vane state and the pressure of a volute piezometric tube of a hydroelectric generating set are collected; s2, when the working door state, the guide vane state and the volute water taking valve state are all closed, the collected volute pressure measuring pipe pressure is stored; s3, calculating the time k required for reducing the pressure of the volute piezometric tube by 0.01 Kpa; s4, calculating the water leakage P of the guide vane per second; s5, calculating the rated water leakage q of the guide vane; and S6, comparing the water leakage amount P with the rated water leakage amount q. The system comprises a monitoring terminal, a test data platform and a program which is stored on the guide vane water leakage test data platform and can be operated. The storage medium is used for storing instructions and implementing the steps of the method during execution. According to the invention, the working intensity of field production personnel and remote management personnel is greatly reduced, the water leakage analysis precision is high, and the real-time monitoring requirement is met.

Description

technical field [0001] The invention relates to the technical field of intelligent control of hydropower units, in particular to a method, a system and a storage medium for analyzing water leakage of guide vanes of a hydropower unit. Background technique [0002] A hydropower station consists of a hydraulic system, a mechanical system and an electric energy generating device. It is a water conservancy project that realizes the conversion of water energy to electric energy. The sustainability of electric energy production requires that the utilization of water energy in a hydropower station is uninterrupted. Through the construction of the hydropower station and reservoir system, the distribution of water resources in time and space can be adjusted and changed artificially, so as to realize the sustainable utilization of water resources. In order to effectively convert the water energy in the reservoir into electric energy, the hydropower station needs to be realized by a hyd...

Problems solved by technology

The current test method is still in the stage of manual recording and calculation. Most of the hydropower stations are located in remote mountainous areas. Every time a test is done, the test team members have to go to the site to do the test, and most of the time is wasted on the road. Therefore, there is an urgent need for an automatic execution method. Method for detecting and testing water leakage
