基于3G的无线传输在水电厂计算机监控系统中的应用

摘要

This paper introduces the practical application of wireless VPDN technology based on 3G in the automatic control of hydropower plant,and solves the problem that the construction of the cable communication line between the pump station and the control room can be realized. On this basis,the system constitution and the establishment process of the tunnel are analyzed,and the requirements of the two safety protection of the electric power system are met.%本文介绍了基于3G的无线VPDN技术在水电厂工业自动控制中的实际应用，解决了泵站与控制室之间需建设有线通信线路的问题，实现了集控中心的远程监控。在此基础上，分析了其系统构成及隧道建立过程，并满足了目前电力系统二次安全防护要求。
