摘要
通过分析远程I/O控制的特点,将远程I/O+DCS控制和全DCS控制2种控制方式进行比较,认为远程I/O+DCS控制方案可实现物理分散控制,且调试、维修费用少,性价比高。以天津陈塘庄热电厂2台300 MW机组设计为例,介绍了该方案的应用情况和使用中应注意的问题,指出远程I/O控制的发展前景。
With analysis on the features of long distance I/O control, long-distance I/O＋DCS control is compared with whole DCS control, after comparision, it is considered that the long - distance I/O control has some advantages. The ap plication of long-distance I/O control in design of Chen Tang Zhuang thermoelectricity power plant and matters should be mentioned are introduced, and the development foreground of long-distance I/O control is pointed out.
