摘　　要：主要研究了10kV配电网DSCADA系统中,DSACDA主站与RTU终端采用IEC 60870-5-101规约和循环式远动规约(CDT规约)时,中压电力线载波通信的通信方法;分别针对IEC 60870-5-101规约和CDT规约制定了数据处理方法。两种方法在上海电力公司的工程中加以验证,对测试数据进行了分析,得出中压电力线载波传输配电自动化数据完全可靠的结论。This paper introduces the research on communication methods of medium-voltage PLC in DSCADA system of 10 kV distribution network when IEC60870-5-101 protocol and CDT protocol are used. It discusses the protocols and data processing methods based on them. Both methods are authenticated in the project of Shanghai Electric Power Company. By analyzing the testing data, it makes a conclusion that medium-voltage PLC is reliable for the transmission of distribution automation data.
