[Abstract]:The fault diagnosis of transmission and transformation equipment is an important basis for the evaluation and maintenance of the equipment's running condition. The accuracy and reliability of the method will directly affect the normal operation and maintenance of power transmission and transformation equipment, condition-based maintenance and even the safety and stability of the whole power system. The research and application of on-line monitoring-based fault diagnosis method for transmission and transformer equipment will be one of the effective means to improve the efficiency of equipment condition-based maintenance and improve the ability of fault discrimination. In this paper, the forming mechanism of on-line monitoring technology for transmission and transformer equipment and the traditional analysis method and artificial intelligence method based on transmission and transformation equipment at home and abroad are analyzed. The on-line monitoring system of transmission and transformer equipment condition and its comprehensive intelligent judgment method are designed. The on-line monitoring of transmission and transformer equipment status is realized by using computer system. Finally, the monitoring data of the equipment are compared with the traditional methods and analyzed. The diagnosis results of practical data show that the fault diagnosis method based on-line monitoring is feasible and can effectively improve the accuracy and reliability of transmission and transformer equipment fault diagnosis.
