基于OPC工业标准规范的新型SCADA软件的开发

Development of new SCADA for power industry based on OPC industry standard speci fication

简要说明了电力系统SCADA软件必须能够灵活地集成不同厂家生产的、遵循不同通信协议的现场设备的新问题。应用组件软件的思想以及COM(ComponentObjectModel,组件对象模型)技术,采用客户/服务器的结构模式,开发了基于OPC规范的新一代SCADA软件的服务器程序和客户程序。由于客户程序与服务器程序之间遵循OPC技术规范,不同的客户程序与服务器程序之间可以使用通用方式进行数据交换,从而较好地解决了SCADA软件中的开放性问题。

In this paper,the new problem of SCADA for power industry is briefly introduc ed. The SCADA must be able to integrate the field devices flexibly,which produ ced by different manufacturers and with different communication protocols. The i dea of component,COM (Component Object Model) technique and client/server archi tecture have been used to develop the OPC server/client program in a new type of SCADA for substation. With the OPC technical specification,different clients a nd servers can exchange data by general method,which makes the SCADA open.
