摘　　要：随着高压直流输电技术的不断发展,基于地下管廊的交直流混联系统得到了广泛应用,一方面扩大了智能电网的运行规模,另一方面,对管廊内设备运行可靠性的监控也提出了更高要求。交直流混联系统管廊内运行环境严酷,极易发生严重安全事故等问题。文中建立了对交直流混联系统管廊内状态监测与运行评估的多源信息融合监测系统,将管廊内交直流混联系统重点部位的多源参量进行数字化、智能化处理,提取关键信息,并基于多源信息融合算法对系统运行状态进行分析与评估。当管廊内交直流混联系统运行出现异常时监测系统能够实现快速响应,从而保证管廊内交直流混联系统的长期稳定运行。With the continuous development of HVDC power transmission technology,the AC and DC hybrid sys⁃tems based on underground pipe corridors have been widely used.On the one hand,the operation scale of of the smart grid is expanded and,on the other hand,higher requirements are also raised for the monitoring of reliability of the equipment in the pipe gallery.In view of the issues of harsh operating environment in the pipe corridor of the AC/DC hybrid system and likely occurrence of serious safety accident,the multi⁃source information fusion monitoring system for the state monitoring and operation assessment in pipe corridor of AC/DC hybrid system is set up in this pa⁃per,the multi⁃source parameters of the import position of the AC/DC hybrid system in the pipe corridor is subjected to the digitization and intelligent treatment,the key information is extracted and the the operation state of the system is analyzed and assessed on the basis of the multi⁃source information fusion algorithm.The monitoring system,in case of abnormal operation of the AC/DC hybrid system in the pipe corridor,can be able to achieve fast response so as to assure the long⁃term and stable operation of the AC/DC hybrid system in the pipe corridor.
