Fault diagnosis and evaluation method and system for power equipment of transformer substation

The invention relates to the field of power equipment fault diagnosis, in particular to a transformer substation power equipment fault diagnosis evaluation method and system, and the system comprises a server, a fault diagnosis analysis unit, a self-inspection feedback unit, an image analysis unit, a compensation analysis unit, a judgment analysis unit and a display unit. According to the method, the state data of the power equipment is collected and analyzed, that is, the power equipment fault diagnosis evaluation condition is judged through the two dimensions of the abnormal temperature rise value and the fault probability value, the accuracy and effectiveness of the data are improved through the two dimensions of the used age limit and the preset aging loss compensation correction coefficient, analysis is more comprehensive, and the accuracy and the effectiveness of the data are improved. And comprehensive analysis is carried out through formulated processing and a progressive mode, and secondary verificat
