摘要
DNP是目前电力系统自动化产品市场上的一种主流通信规约,简要介绍了DNP3.0的基本结构和功能,结合基于RTU的电力综合自动化系统开发实例,给出了DNP协议部分功能的具体实现方法,通过该协议系统实现了“四遥”功能。现场运行结果显示,DNP3.0协议具有较高的通信效率和通信可靠性,运行方式灵活多样,误码率极低,完全能够满足电力系统实时性和可靠性的要求。
DNP is a kind of main communication protocol in the market of automation product of power system at present.Introduces the basic architecture and function of DNP3.0.Associated with a realistic application example of integrated automation system based on RTU ,the detailed implementation of some components and functions of DNP3.0 is presented.＂Four remote＂is realized in the system through the protocol.The running result on spot reveals that the communication efficiency and the communication reliability are high of DNP3.0 protocol.And the protocol has flexible running mode and low bit error rate,it can satisfv the require of the real-time and reliability in the Dower system.
