本工程在锅炉有众多二次风分风门采用Ff现场总线技术 – Ff
Application in Boiler Secondary Air Damper Control
− 设计初衷:由于锅炉二次风分风门众多(74个),原先设计为1个
DCS指令控制一组风门,风门没有位置反馈不利于燃烧控制与管理,
且需要大量的控制电缆及接线。为了更好的控制管理这些二次风分
风门及节省安装调试成本顾选用了Ff总线技术。根据二次风分风门
比较集中的特性,每台机组分了12段Ff总线
− 74 sets Boiler Secondary Air Damper of each boiler, One DCS
command Signal for each group damper, diFficult combustion
control due to no feedback for damper position. Too much control
cable and wiring. With Ff bus application: Less cable & installation,
and better control & management, 12 segments for each boiler。

10. 主机Ff配置方案介绍 -Ff Application in Unit DCS
节省了大量的卡件及机柜空间,常规至少需要22
块AO,11块DI(或11块AI),使用Ff技术后只需要6块
Ff卡件
节省大量电缆,常规至少需要74个*150米=11100
米多芯电缆,使用Ff技术后只需要12段*200米=
2400米Ff电缆
使用AMS管理后,能对74个门进行设备管理,大
大减少因设备故障带来的安全隐患
- Significant Saving in IO module & Cabinets:
traditional minimum configuration(22 x AO
modules, 11x DI modules, or 11 x AI modules) vs
Ff configration ( 6 x Ff modules)
- Significant Saving in Cables: traditional
minimum design( 74 x 150 m = 111,000 m, multi-
core cable) vs Ff configuration ( 12 x 200 m =
2,400 m, Ff cable)
- Significant Potential risk reduced with AMS
device management for 74 positioners

15. Ff使用总结 – Ff Experience Summary
Ff安装调试前期碰到的一些问题
• 对施工单位的前期培训不足,
•部分Ff电缆敷设、接线不符合规范。
•变频装置及其动力电缆离取样设备较近,导致高频
干扰窜入。
•仪表架没有较好的接地。
•电气部分未考虑对变频器高频干扰输出的抑制。
Some issues during Installation &
Commissioning
•No enough Training for construction team
•Some improper Ff cable laying & wiring
•Interfere from Variable Speed Device
•improper grounding of Instrument stand
•No pre consideration for preventing high-frequency
interference from electric works
