摘　　要：系统用于对50 Hz交流电从A地经数十千米(甚至数百千米)输电线路输送到B地后产生的电压相角(或相位移)的在线测量。包括两个功能完全相同的测试装置:A号机和B号机,两机在同步时钟控制下进行数据采集,各记录5 min左右数据后,分别将数据导入PC机,通过NI/CVI LabVIEW开发平台进行分析处理、计算并显示输出结果实现对电压相角的及时监控,为电力系统稳定、安全运行提供有力保障。The system is suitable for the online measurement of voltage phase（or phase shift）generated by 50Hz AC after tens of kilometers even hundreds of kilometers transmission line. The system includes two identical testing devices of A and B. The two devices collected the data under the control of synchronous clock,and the data is sent to PC after each 5 minutes. The timely monitoring of the voltage phase is realized by analysis and process,computing and display the output result through NI/CVI LabVIEW development platform,which provided a powerful support for the power system stability and safe operation.
