A Panoramic Monitoring Method for Steady State Conditions of High-voltage Direct Current Transmission Converters Based on VR Technology
In order to prevent the commutation failure of HVDC converter,reduce the recall rate of panoramic monitoring of the working condition of HVDC converter,and improve the monitoring efficiency and accuracy,a panoramic monitoring method of converter under steady state condition based on VR technology is proposed.This paper analyzes the conduction condition and current change of the bridge arm during inverter commutation,and uses VR technology to build a virtual environment model of the converter from four dimensions,logical device,logical node,data object and data attribute.Based on the 3D data and vari-ous parameters,the feature fusion is carried out,the information matrix of converter operation condition is established,the fault judgment index value is given,and the VR shared space is used to complete the information exchange and analysis between various states,the panoramic monitoring of HVDC converter under steady state condition is realized.Experimental results show that the proposed method has high monitoring efficiency and low recall rate,can achieve accurate monitoring of fault in-formation,and ensure the stable operation of the converter.
