摘　　要：为了提高现有输电线路的输送容量,提出一套新型高压输电线路动态增容计算模型和监控方法,其中实时动态增容在线监测系统的数据传输采用通用无线分组业务(general packet radio service,GPRS)技术,监控服务器软件平台采用虚拟仪器LabVIEW进行编写开发,包括数据接收、数据处理及数据查询等基本功能模块。现场实际应用中,在软件平台上观测到输电线路导线温度与弧垂计算值有较好的线性关系,可为下一步线路弧垂短期预测和预警研究提供参考依据。For improving existing transmission capacity of transmission line, this paper proposes a new set of dynamic increas- ing capacity calculation model for high voltage transmission line and monitoring method of which data transmission of the re- al- time dynamic increasing capacity online monitoring system adopts general packet radio service technology and the moni- toring server software platform uses virtual instrument LabVIEW to proceed programming and development including basic function modules such as data acceptance, data processing and inquire and so on. In locale practical application, it is ob- served in software platform that there is good linear relation between conductor temperature of the transmission line and cal- culated value of sag which may provide reference for short- time prediction and early warning study for sag of the line.
