Abstract

The invention discloses a water turbine equipment state remote monitoring method of a water turbine generator set. The method comprises the following steps of 1, installing various state monitoring subsystems on water turbine equipment of the generator set, and establishing a centralized monitoring and diagnosis system; 2, establishing a unified standardized data platform based on the compositionof a conventional state monitoring system; 3, compiling unified data interface platform software according to communication protocols, rules and requirements; and 4, according to the characteristics of the monitored data of the water turbine equipment of the generator set, combining the actual conditions of multiple units and multiple monitoring systems. According to the method, the function of integrating real-time data acquisition and processing, online data analysis and storage, monitoring and analysis and diagnosis is achieved, various state information of a water turbine unit can be quickly and effectively reflected, so that the running state and running trend of the water turbine unit are clear, the state analysis is carried out for professionals, and the expandability and the working stability are high.

Description

technical field [0001] The invention relates to the technical field of water turbines, in particular to a method for remotely monitoring the state of water turbine equipment of a water turbine generator set. Background technique [0002] A water turbine is a power machine that converts the energy of water flow into rotational mechanical energy, and it belongs to the turbomachinery in fluid machinery. As early as around 100 BC, the prototype of the water turbine appeared in China - the water wheel, which was used to lift irrigation and drive grain processing equipment. Most modern water turbines are installed in hydropower stations to drive generators to generate electricity. In a hydropower station, the water in the upstream reservoir is led to the turbine through the diversion pipe, which drives the turbine runner to rotate and drives the generator to generate electricity. The water that has done work is discharged downstream through the tail water pipe. The higher the w...
