Research on Electromagnetic Compatibility of Distributed Control System in Petrochemical Installation
The electromagnetic compatibility of Design specification for distributed control system in petrochemical industry requires that DCS equipment does not cause negative electromagnetic interference in other equipment,nor will it be excessively sensitive to external electromagnetic interference.The relative concept of electromagnetic compatibility is introduced,and the electromagnetic emission requirements and anti-interference requirements of electric equipments of DCS are sorted out,the electromagnetic protection measures of DCS are put forward.Through summarizing the electromagnetic compatibility design key points of control system in the petrochemical installation,reference for design and application of electromagnetic compatibility in DCS engineering design is given.
