程工作量和时间，减少了故障点并为客户提供一个统一的环境，以在一个协作视图中控制和监控他们的资产。此外,它增强了V/A系列DCS的开放性，提供与来自多个供应商的多种设备和协议类型的互操作性。
使用Foxboro I/A系列系统，客户可以保持他们的设备和供应商偏好，因为该平台可以适应他们。Foxboro V/A英维思运营管理公司使用Foxboro⑧/A SeriesR分布式控制系统(DCS)提供一-流的给水控制系统。近的实施提供了操作理念的提升，改善了启动和运行时间的性能，并大大减少了非计划的机组跳闸停机。
这些先进的控制技术可以减少操作员所需的互动，增加自动控制的时间-包括在大多数机组跳闸的启动和关闭期间-使整个控制系统更有能力处理过程中的干扰条件和正常运行。在/ASeries DCS被安装在Fort Calhoun Station的Omaha Public Power District的给水控制上之前，有许多操作上的挑战。控制装置没有得到很好的调整。在功率变化期间，液位扰动并不罕见，低液位控制不佳。
该设施的高 级核设计工程师ohn Steinke说:"” 在旁路给水阀和主阀上采用分程三要素控制，允许自动控制来处理从旁路到主阀的切换。这就减少了操作人员的直接人工互动，从而减少了操作人员的挑战。我们还轮换了我们的蒸汽发生器给水泵。分程三元件控制大大减少了与旋转这些泵有关的扰动。更精 确 的调整和控制使我们机组的能力系数(发电能力)大化，同时消除了操作该系统的持证操作人员的不必要的负担。到目前为止，我们还没有因为DCS而跳闸，也没有获得额外的停机时间。
Product name :PROFIBUS-DP Communication interface module - FBM223
Order number: P0917HD
Short description:
The PROFIBUS-DP Communication interface module (FBM223) provides connections between PROFIBUS-DP slave devices, such as programmable logic controllers (PLCS), I/O modules, and field I/O devices, and I/A series systems
Mouth.
Product type: Enabling technology
Technology and Overview:
The main feature of the FBM223 module is that it complies with the PROFIBUS-DP fieldbus specification. - Full support for all device variables and diagnostic messages. - Integrate PROFIBUS data from the device to the /A system
Column control database. The FBM223 and its associated terminal components (TA) are suitable for installation in Level 1, Zone 2, and Zone 2 locations. Foxboro I/A Series DCS for water supply control Systems Competitive Advantage The foxboro DCS module 20x-23x provides A reliable, high-capacity interface between DeviceNet /O devices and V/A series DCS for data exchange without expensive gateways. The module saves work
Process effort and time, reducing points of failure and providing customers with a unified environment to control and monitor their assets in one collaborative view. In addition, it enhances the openness of the V/A series DCS, providing interoperability with multiple devices and protocol types from multiple vendors.
With Foxboro I/A series systems, customers can maintain their device and vendor preferences as the platform ADAPTS to them. Foxboro V/A Invensys Operations Management uses the Foxboro⑧/A SeriesR Distributed control System (DCS) to provide one-stream feedwater control systems. Recent implementations have provided operational concept enhancements, improved start-up and uptime performance, and significantly reduced unplanned unit trip shutdowns.
These advanced control technologies can reduce the interaction required by the operator, increase the time of automatic control - including during the start-up and shutdown of most unit trips - and make the overall control system more capable of handling interfering conditions during the process and normal operation. There were a number of operational challenges before the /ASeries DCS were installed on the feedwater control in the Omaha Public Power District at Fort Calhoun Station. The controls are not well adjusted. During power changes, level disturbances are not uncommon and low level control is poor.
ohn Steinke, senior nuclear design engineer at the facility, said :" The use of split three-element control on the bypass feed valve and the main valve allows automatic control to handle the switch from the bypass to the main valve. This reduces the direct human interaction of the operator, thus reducing the challenges for the operator. We also rotated our steam generator feed pumps. Split range three-element control greatly reduces the disturbance associated with rotating these pumps. More precise adjustment and control maximizes the capacity factor (generating capacity) of our units while eliminating unnecessary burden on the licensed operators operating the system. So far, we have not tripped or gained additional downtime due to DCS.
