摘要
大型火力发电厂的主设备控制水平先进 ,而外围设备的控制水平落后 ,大多还停留在上世纪 80年代常规控制仪表的水平。改造外围设备的控制系统 ,使原来分散就地控制的外围设备实现集控运行 ,将大大提高火电厂自动化水平。iFIX工业自动化软件 ,具有很好的开放性、安全性以及扩展性 ,将它应用于外围设备的控制系统改造 ,可最大限度地利用现有控制设备 ,减少硬件投入 ,缩短开发周期 ,并且改造后的外围控制系统既能符合生产工艺 。
The control systems of the main equipments in a large power plant are advanced,while those of the peripherals are made out of the conventional control instruments using in 1980s.If the control systems of peripherals is reconstructed into central control operation,it would aggrandize the automation level of a power plant.Due to the exoteric,safety and expansibility of the iFIX software,it’s application in peripherals reconstruction can make use of the existed equipments at most,and decrease the investment and save time.The reconstructed control systems can meet the production need.
