22. 经济性分析(定性)
Benefit Analysis (Qualitative)
系统投资:由于Ff总线系统采用的模块数量相对减少,节省了机柜、控制室的空间,故其系统
投资与按常规DCS系统设计的系统投资相差不大。
仪表及安装费用:Ff总线型变送器和阀门定位器等仪表设备的投资目前虽较常规/带HART协议
变送器的投资多10%~30% ,但由于Ff总线系统使用的安装材料(电缆、桥架等)大大节省,
安装工作量明显减少,而且随着点数增多,这方面的优越性会体现得越是明显。在通常的大型装
置中,I/O总点数一般总是成百上千安装费用和时间通常可减少三到四成,所以这项费用不仅不
会增加,实际还会有所减少。
调试费用:由于采用总线技术给调试带来的诸多便利,调试的工期缩短,投入的人工成本大大
降低,故可节约投资在50%以上。
维护费用:由于采用AMS和嵌入诊断功能的Ff现场仪表设备,可节省50~70% 的维护时间和费
用。
System investment: Because the Ff system uses relatively less modules which can save
cabinets, control room space. So the investment is near with conventional DCS system .
Instruments and installation costs: Ff transmitters and valve positioners costs are 10% to
30% higher compared with conventional / HART transmitters , but since there are huge
saving in the Ff bus system installation materials ( cables, bridge, etc.) ,man-hours, the total
cost does not increase, even can decrease, especially in large projects.
Commissioning costs: As a result of the intelligent bus technology, it’s easy to
commission, shorten the commission duration greatly, reduce the labor costs of the
investment, and finally save more than 50% of the investment.
Maintenance costs: As a result of the AMS and embedded diagnostic function in Ff field
instrumentation, we can save 50 to 70% of maintenance time and costs.
