Problems solved by technology

[0004] There are many kinds of equipment faults. When a fault occurs, how to obtain effective information to express equipment faults through detection means is an important issue in equipment fault management. The existing fault diagnosis methods only use the changes in electrical parameters to diagnose faults. The recognition accuracy is low, resulting in inaccurate fault diagnosis results

Abstract

The invention relates to the technical field of artificial intelligence, in particular to a power grid equipment fault diagnosis method and system based on artificial intelligence. The method comprises the following steps: collecting various types of electric parameter data of power grid equipment, wherein the data of each type of electric parameter form a real-time updated data sequence; predicting the prediction data of the electric parameters corresponding to the future time according to the data sequence of each type of electric parameters, and forming a first data sequence together with the data sequence; performing anomaly evaluation on the first data sequence of each type of electric parameters to obtain an anomaly index, and obtaining an anomaly value sequence according to the correlation of each two types of electric parameters and the corresponding anomaly index; and reasoning the real-time abnormal value sequence to obtain a real-time result of equipment fault diagnosis. According to the embodiment of the invention, the accurate real-time fault diagnosis can be carried out on the power grid equipment, and the safety protection capability of the system is improved.

Description

technical field [0001] The invention relates to the technical field of artificial intelligence, in particular to an artificial intelligence-based grid equipment fault diagnosis method and system. Background technique [0002] Electric power is the basic industry of national economy and people's life, its supply and security play a vital role in national security strategy, economic and social development. However, as the complexity of the power system increases, especially in the case of multiple faults or incorrect operation of protection devices, the workload to be processed is extremely large, so power system failures are inevitable. When the power grid equipment in the power system is in an abnormal state or fails, if the power failure cannot be diagnosed quickly and repaired in time to restore the normal operation of the power grid as soon as possible, it will cause power outages that affect daily life, and may cause huge economic losses. [0003] In practice, the inven...
