With the progress of science and technology and the improvement of modernization level, electrical and mechanical equipment is continuously developing towards the trend of large-scale, integration and automation, the system composition and the internal structure are gradually complicated, and the relationship between different electrical equipment and mechanical equipment is more and more close, so once a certain part of the equipment breaks down in the operation process, and the faults develop and accumulate to a certain degree, major accidents of the electrical and mechanical equipment system can be caused. Meanwhile, along with the progress of sensing and information technology, the state monitoring of the equipment is inevitably developed towards a direction of more comprehensive perception, more accurate measurement and more intelligent decision making. The problem of extremely unbalanced geographical distribution exists in combination with national power grid energy. The hydropower resources and the load of a national power grid are reversely distributed, abundant electric energy sources are distributed in the western region and the regions to the north of the western region, but the regions are key high-power-consumption load regions in the south and east and the coast, so that the current situations that the electric energy transportation cost in the hydropower resource field is extremely high, the loss of wind energy sources is serious, and a large amount of electric energy sources are wasted in a power transmission system in China are caused.
In a direct-current transmission system, the converter valve is a key device for realizing rectification and inversion functions, alternating current-direct current conversion and power transmission. As the high-voltage direct-current system in China is increasingly large, the structure of the converter valve is increasingly complex, and the probability of equipment failure is greatly increased. The diagnosis difficulty is increased because the fault of the equipment has strong nonlinearity, concurrency, uncertainty and the like. The operating state of the converter valve is related to the reliability of the whole direct current transportation project.

The traditional fault prediction method can only discover and judge discovered and serious typical equipment faults, but has relatively insufficient capability of pre-judging some invisible faults, and the characteristic frequency and the frequency multiplication of the fault signal frequency are difficult to distinguish in a complex noise environment. However, no device capable of collecting data aiming at voiceprint information of the ultra-high voltage converter valve exists at present, so that certain data defects exist in the existing ultra-high voltage converter valve monitoring.
