基于S7-414H冗余系统的四合一机组保护策略

摘要

以某化工企业四合一机组自控系统为例，介绍了以西门子S7-414 H为核心的冗余控制系统，在硝酸四合一生产过程控制中的应用。重点介绍了四合一机组的系统硬件配置和机组控制中所采取的保护策略。%Take the automatic control system of four-in-one unit in one factory as an example, the paper introduces the application of Siemens S7-414 H system who acts as a high reliability and stability control system in the nitric four-in-one control processes. Mainly describes the hardware configuration and the important protection strategies have taken in the control system.
