IEC60870-5传输规约的应用及试验

讨论了变电站与控制中心的通信信息和传输特点,分析了变电站内远动、继电保护、故障录波、安全自动、环境监控及生产等装置的信息内容和传输要求以及生产控制信息的传输现状,指出IEC60870-5系列传输规约的101为基本远动任务配套标准,102为满足电量计费系统的传输,103为继电保护信息的需要。提出对于大型变电站与控制中心间较复杂的数据信息传输,利用网络允许多协议同时并存和较高的传输速率及容量的特性,以一个网络化的数据传输通道同时采用IEC60870-5系列的4个配套标准(101、102、103、104)传输信息;在较小的变电站,用1 200～9 600 bit/s速率的串行通道,在扩展配套标准IEC60870-5-101引入同用分类服务,实现远动、保护等信息同时传输的方案。指出应用中信息传输时间、对多运行状态对象的控制、继电保护定值的传输、传输厂站信息文档等为尚需解决的问题。

Application and test of IEC60870-5 transmission protocol

The communication information between substation and control center is discussed,as well as its transmission features.The information contents of substation devices and their transmission requirements are analyzed,such as RTUs,protections,fault recorder,automatic safety,environment monitor,etc..The current conditions of information transmission are described.In IEC60870-5 series of transmission protocol standards,section 101 is for basic remote control tasks,102 is for remote electric energy metering and 103 is for relay protections.For the complex data transmission between large substation and control center,the networked communication channel with higher transmission speed and capacity is recommended,applying multiple protocols of four IEC60870-5 series standards(101,102,103,104).For small substations,the serial communication channel with 1 200 ~ 9 600 bit / s speed is suggested,applying IEC60870-5-101 standard with extended classified service for transmitting the information of remote control and protection simultaneously.Some problems to be solved in the applications are pointed out,such as transmission time,multi-running-status-object control,protection-setting transmission,substation document transmission,etc.
