The invention discloses a power plant device fault diagnosis system and method based on artificial intelligence, and the system comprises a fault database, a feature extraction module, a feature comparison module, a target equipment selection module, and an information transmission module. The fault database is used for storing characteristics of each device of the power plant when faults occur. The feature extraction module is used for extracting current fault features when faults are detected, and the feature comparison module performs similarity comparison on the current fault features and features of each device in the fault database when faults occur, and if only one device in the fault database has a similarity greater than or equal to a similarity threshold between the feature when the device has a fault and the current fault feature, the device is a target device, otherwise, the target device selection module selects a target device from the devices of the power plant according to similarity information and historical fault information, and the information transmission module is used for transmitting alarm information of failure of the target equipment.
Description
technical field [0001] The invention relates to the technical field of power plant equipment, in particular to an artificial intelligence-based power plant equipment fault diagnosis system and method. Background technique [0002] A power plant, also known as a power station, is a factory that converts various primary energy stored in nature into electrical energy. Power plants have a variety of power generation methods: those that rely on thermal power are called thermal power plants, those that rely on hydropower are called hydropower plants, and some power plants that rely on solar, wind and tidal power, etc. Faults will inevitably occur. When a power plant fails, it will cause a shortage of power supply and affect the normal operation of society. Because, in the event of a breakdown in a power plant, it is important to be able to quickly locate the failed device. However, in the prior art, it often occurs that the faulty equipment is mistaken and a misdiagnosis occurs....
