Empirical Mode Decomposition-based Online Fault Monitoring of High Voltage Transmission Lines
In order to ensure safe and stable operation of high voltage transmission lines,an empirical mode decomposition algorithm is introduced and an online fault monitoring method is proposed.First real-time collection of high voltage trans-mission line operation data and standardized processing of the collected data are carried out.Second the operating fault characteristics of HV transmission lines are extracted from the processed data by the empirical mode decomposition algo-rithm,and consequently used to determine and online monitor faulty sections.The experiment shows that after the appli-cation of the proposed online monitoring method can achieve results always close to actual fault situation and online ran-ging errors lower than 0.12%.
