Fault Status Information Monitoring Technology for Large Complex Electromechanical System

摘要

In order to improve the accuracy of fault state monitoring of electromechanical system, a fault state informatization monitoring technology for large complex electromechanical system is proposed.Based on the standard PD (Partial Discharge) signal expression derived from the traditional communication theory, the characteristic value of the fault signal is calculated, and the feature of the fault state signal is extracted by using the functions of the time and frequency of the fault state of the electromechanical system.Experimental results show that compared with the information monitoring technology based on support vector machine, the proposed fault monitoring technology has a higher monitoring accuracy.
