SIS Application & Standard SIS 应用及相关标准,Avoid Risks And Dangers In Your Plant By Applying Safety System 运用安全系统以规避风险和危险,Definition of a Safety System 安全系统的定义,Safety systems are designed to respond to conditions of the plant, which may be hazardous in themselves, or if no action were taken could eventually give rise to a hazard. They must generate the correct outputs to prevent the hazard or mitigate the consequences. 安全系统是设计为当工厂本身发生危险情况，或，如果不采取行动就会最终导致风险增加，在这些情况下，安全系统必须产生及时、正确的输出，来防止任何危险发生或减轻后果。,Some common names used for Safety System : 安全系统的常用名称 : ESD Emergency Shutdown System 紧急停车系统 SIS Shutdown Interlock / Instrument System 停车连锁/仪表系统 IPS Instrument Protective System 仪表保护系统 FSSS Flue Safety Sing System 锅炉安全监视系统 FGS Fire & Gas Protective System 火和气保护系统 ITCC Integrated Turbine & Compressor Control 综合透平压缩机控制,Safety System 安全系统类型,Safety System Applications 安全系统应用范围,Boiler / Burner Management Systems 锅炉/燃烧管理系统 Continuous Production Units - Refining and Petrochemical Process 连续性生产过程-炼油厂和石油化工厂 Batch Processes 批量生产过程 On- and Offshore Oil & Gas Exploration and Production Facilities 岸上/海上油/气体勘探和生产 Compressor & turbine Monitoring / Safeguard 压缩机和透平机监视/防护 Fire & Gas Detection 火和气体监测 Loading and Storage Facilities 装载/储存设备 Pipeline Safety Management Systems 管道安全管理系统,Two Appraisement Index for Safety System 安全系统的两大评价指标,DependabilityCant refuse action 可靠性不能 拒动 UsabilityCant false action 可用性不能 误动,Safety Control System Theory, Standards and Attestation安全控制系统的理论、标准和认证,Theory: 理论 Markov Modeling Methodology MTTF, MTTR, MTBF, Standards: 标准 IEC61508, IEC61511, ANSI/ISA S84, NFPA/UL98, DIN 19250 SIL Attestation: 认证机构 TUV,ESD SYSTEM TV Rheinland - TV certification ensures, per DIN and IEC standards, the functionality of SIS systems for critical process applications requiring maximum safety and uninterrupted operation.
