Study on the Fault Diagnosis of High-Frequency Switch Rectifier Module in High Voltage Direct Current Communication Power Supply
high voltage direct current communication power supply is an important part of High Voltage Direct Current transmission system,and its reliability directly affects the safe operation of the system.In this paper,a comprehensive diagnosis method is proposed for the fault diagnosis of high-frequency switching rectifier module.The method includes four steps:data collection,fault feature extraction,fault mode analysis and diagnosis decision making.The experimental results show that the proposed method has excellent performance in many typical fault scenarios,with high fault detection rate,classification accuracy and short diagnostic response time.The research results are of great significance to ensure the safe and stable operation of high voltage direct current transmission system.
