摘　　要：为提高智能水电厂水位测控装置的智能化程度,提出了一种智能水位变送器的设计方案。通过对智能水电厂通信网络结构方案的分析,指出数据格式无法满足智能电网技术的通信要求;明确智能水位变送器的通信功能需求,在此基础上搭建智能水位变送器系统硬件平台;然后按照IEC 61850标准要求建立智能水位变送器的信息模型,完成通信服务配置并给出了系统组成框图。最后设计了一套实验方案,在2台电脑上运行IEDScout模拟软件接收数据,使用Wireshark软件抓取并分析MMS数据包。实验结果表明:构建的信息模型能满足水位数据使用IEC 61850标准通信的要求,信息具有共享性和自描述性;所搭建的系统平台通过信息模型重构或扩展可以满足其他非电量数据的采集处理需要,符合一次设备智能化的建设战略要求。To improve the intelligence of water level measurement and control devices in intelligent hydropower plant, we present an intelligent water level transmitter in this article. work structure of hydropower plants, we smart grid, and expound the demand for Through analysis on the communication net- point out that the data format does not meet the technical requirements of intelligent communication function of transmitters. On this basis, we build a hardware platform for smart transmitter system, and establish the information model of smart transmitter in line with IEC 61850 standard. Furthermore, we complete the communication service configuration and give the block di- agram of the intelligent transmitter system. Finally, we design an experimental program of running IEDScout soft- ware to receive data on both two PCs, and captured and analyzed MMS packet by Wireshark. Experimental result shows that the constructed information model and communication server mode meet the requirement of water level data posed by IEC 61850 standard. The information is self-descriptive and has a strong character of sharing. With the information model reconstruction or expansion, system platform has the capacity to meet other non-power da- ta＇ s acquisition and processing requirements, which is in line with the strategic requirement of primary equipment intelligence.
