摘要
以华能上安电厂补给水程控系统改造为例,介绍了一种基于IFix软件的SCADA控制系统。电厂原有化学水处理系统一般由人工按钮完成控制,并通过模拟屏显示设备状态。其自动化水平较低、安全性差、故障率高、工作人员强度大。采用Unity Pro与IFix工业组态软件,通过开放的网络协议,即工业以太网技术实现系统的自动控制;可靠的硬件系统和友好的人机界面,大大提高了系统的自动化水平及安全性,降低了运行人员的劳动强度,实现了无人或少人值班。其运行结果表明,该控制系统可靠性较高,运行稳定,具有一定的实用推广价值。
Taking the example of rebuilding project of feeding water programmed control system of Shang＇an power plant, one SCADA control system based on IFix software was introduced in the article. The former chemical water treatment system ofthe power plant was composed of operating buttons and PLC, and the status of equipment was displayed on mimic control panel. The system only offered very low level of safety and automation, the operators suffered high labour intensity. By adopting Unity Pro and IFix industrial configuration software, through open network protocol, industrial Ethemet, the automatic control system was realized. Reliable hardware and userfriendly human machine interface highly increased the level of automation and safety, the labour intensity was also decreased. Less operator intervention, even unmanned operation can be implanted.
