摘要
提出一种针对中小型水电厂的开放型水电厂自动化系统设计方案。介绍了系统的结构及软件设计方案,系统现地控制单元中的可编程控制器(PLC)及保护装置直接接入以太网,通信采用IEC 60870-5-104协议及OPC技术,监控软件的设计采用面向对象、多进程、多线程、COM等技术。给出了系统数据点的标识方法、OPC服务器访问的实现过程、IEC 60870-5-104协议的应用经验等。系统标准化程度高、开放性好,在现场运行可靠稳定。
An open design scheme is presented for medium and small hydropower plant automation system. Its system structure and software design are introduced. The PLCs（ Programmable Logic Controller） of local control unit and the protection devices are connected directly with Ethernet. IEC60870-5-104 protocol and OPC（Ole for Process Control） are used in communication. Tech- nologies of OOP,multi-procedure,multi-thread and COM are used in the design of supervisory and control software. The identification of system data,the implementation of OPC server accessing and the application experiences of IEC60870-5-104 protocol are described in detail. The system runs reliably with better standardization and openness.
