Correlation Analysis of Defects of Valve Base Electronic Equipment in HVDC Transmission System Based on FP-Growth Algorithm
The converter valve control equipment is the core equipment of the DC transmission system,and the abnormal analysis of the valve base electronic equipment is the basis to ensure the stable and reliable operation of the DC transmission system.A defect correla-tion analysis method for HVDC valve-based electronic equipment based on FP-Growth algorithm is proposed.Firstly,based on the basic structure and principle of valve-based electronic equipment,the defect data of valve-based electronic equipment are collected.Then,the original data are preprocessed,quantized and encoded,and then imported into the FP-Growth algorithm.By constructing FP-Tree,calcu-lating its support and confidence,the defect characteristics and influencing factors of valve-based electronic equipment are analyzed,as well as the correlation between components.The proposed method can efficiently realize the correlation analysis and fault traceability of the core equipment defects of the HVDC transmission system,and provide a theoretical basis for the formulation of maintenance strate-gies for operation and maintenance personnel.Finally,the effectiveness of the modified method is verified by a simulation example of the defect data of converter valve base electronic equipment of actual DC transmission system.
