为了防止高压直流输电换流器换相失败、降低高压直流输电换流器工况全景监测的召回率、提高监测效率及精度,提出基于VR技术的换流器稳态工况全景监测方法.在分析逆变器换相时桥臂的导通工况以及电流变化情况的基础上,利用VR技术从逻辑设备、逻辑节点、数据对象和数据属性4个维度,构建换流器的虚拟环境模型.基于三维数据和各项参数进行特征融合,建立换流器运行工况状态信息矩阵,给出故障判定指标值,利用VR共享空间完成各种状态间信息交互和解析,实现高压直流输电换流器稳态工况的全景监测.实验结果表明,所提方法具有较高的监测效率和较低的召回率,可实现故障信息的精准监测,保障换流器的稳定运行.
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.
