XO08R2 应用工控行业DCS系统ABB模块
XO08R2 应用工控行业DCS系统ABB模块预测技术的EPA验证系统在海湾地区的成功为该地区的进一步应用开辟了道路。许多人看到了拥有一个易于适应的“智能”系统的优势:其性能得到了国际公认的环境机构的认可。预测系统可以提高传统CEMS的可用性。在CEMS不可用或不可用的情况下,PEMS实际上可以取代传统的分析仪。除了这些优势外,ABB解决方案提供的模拟功能使工厂能够在非侵入性环境中研究可能的操作改进,并确定运行该过程实践。它们还能够提前测试优化系统,以满足当地环境法规的要求。分布式控制系统的典型架构是一个有组织的控制器层次,用于监测和控制任何类型的发电厂中的过程。DCS基于接口设备分散的概念,用于控制整个项目,使用双冗余光纤通信总线与工厂的远程区域进行接口。有许多商业DCS,市场上的许多供应商都在提供这些系统,如ABB、霍尼韦尔、西门子、罗克韦尔(Allen-Bradley)和通用电气。DCS提供了一个单一的平台来自动化工业工厂的控制和操作。分布式控制系统由以下硬件和软件组件组成:
现场换能器/传感器
PLC/控制器
具有人机接口(HMI)的工作站
带显示器的远程/本地/自动/手动控制
主应用程序服务器和辅助应用程序服务器
用于长期归档的Historian、公用事业数据仓库或归档服务器
主要公共数据库,如SQL或Oracle
事件和报警管理系统
冗余客户端服务器网络
通用工程套件

At the field level are instruments like variable frequency drives, valves, motors, transformers, etc. These instruments are placed nearer to the process to control and sense and then transmit these parameters to the DCS. The actuators, pumps, sensors, and motors are interfaced with relevant, dedicated PLCs. The field level is the initial and most basic level of any DCS and covers many different sensors (speed, flow, voltage, and pressure) and outputs. All of this equipment is monitored and controlled by the controller.The controller-level information is sent to the operator consisting of multiple servers. The servers collect and save the process data that is coming from the sensor through PLC nodes in the SQL database management system (DBMS) in the historian server (sometimes called archiving server). The historian server provides data that can be several years old, depending on the storage configuration.The pair of redundant servers are labeled ‘primary’ and ‘secondary’; if the primary server fails, the secondary server will take the real-time process data because the operation and monitoring are very critical for any power plant. The application programs in these servers read and write data, in other words, receiving and sending parameters to the PLC or controllers. The same process data is then displayed via a graphical interface to the operator, who can issue the commands to wicket gates, unit stop commands, and valves and then open/close the breakers.
