摘要
针对卡琳娜(Kallina)循环发电站循环工质的独有特性,配套设计的控制解决方案由分布式控制系统(DCS)、SIL3认证的安全仪表系统(SIS)紧急停机系统以及现场仪表组成。通过合理的热控仪表选型及监控信号安全隔离设计,实现了对Kallina循环发电站控制设备的运行状态,以及对机组发电运行工况的所有参数和数据的准确采集和监控。综合利用先进的智能控制技术[3],对Kallina循环发电站的关键工艺参数进行准确调节,严谨编制机组保护跳机联锁控制逻辑、开机自动控制及并网后的自动调节程序,保证了Kallina循环发电站生产运行的安全性能,有效地提高了热能转换以及发电效率。Kallina循环发电站的成功投运及并网发电,验证了为其配套设计的仪控岛是一套安全、可靠、自动化程度高的智慧控制系统。
The control solution,that designed according to the unique characteristics of cycle working fluid of the Kallina cycle power station,was composed of distributed control system(DCS),SIL3 certified SIS emergency shutdown system and field instruments.Through reasonable selection of the process control instruments and safety isolation design of the monitoring signals,the operation status of the control equipment of the Kallina cycle power station and all parameters and data of the operation conditions of the unit were accurately collected and monitored.With the comprehensive use of advanced intelligent control technology for accurate adjustment of the key process parameters,as well as rigorous compilation of the interlock control logic of the unit protection tripping operation,and programs for automatic control after startup and automatic adjustment after grid connection,the safe operation of Kallina cycle power station was guaranteed,and the efficiency of thermal energy conversion and power generation was effectively improved.The successful commissioning and gridconnected power generation of the Kallina cycle power station verifiedthat the instrument and control island designed for it is a safe,reliable and highly automated control solution.
