Description

technical field [0001] The invention belongs to the technical field of data analysis, and more specifically relates to a power system fault classification method and system based on an ID3 algorithm. Background technique [0002] The power system consists of generators, transformers, busbars, transmission and distribution lines and electrical equipment. Various electrical components and systems are usually in normal operating condition, but there may also be faults or abnormal operating conditions. As the scale of the power system becomes larger and the structure becomes more and more complex, faults are inevitable. In the whole power production process, the most frequent and dangerous fault is the short circuit fault. The causes of short-circuit faults include aging or mechanical damage of electrical equipment insulation materials, overvoltage caused by lightning strikes, natural disasters causing towers to fall to the ground or disconnection, short-circuits caused by bir...
