摘　　要：以广东大鹏液化天然气管线项目为工程背景,介绍了BB-RTU在中国第一条液化天然气管线项目SCADA系统中的应用,以坪山分输站为例,详细描述了RTU系统软硬件配置、网络构成,并分别针对液化天然气输气站场的主要生产装置,包括过滤分离器系统、气体计量系统、气体加热系统、压力流量调节系统、仪表风压缩机系统等的工艺和生产特点,介绍了RTU控制系统的主要功能、逻辑及控制回路的特性和实现方法。Taking the Guangdong Dapeng LNG pipeline project as the engineering background, the application of BB-RTU in SCADA of the first LNG pipeline project in china is introduced. Taking the Pingshan Offtake Station as an example, the software and hardware configuration and network structure of RTU are described in detail. Aims at the process ＆ operation features of main production equipments in LNG offtake station separately including filter separator system, gas metering system, preheater system, pressure ＆ flow regulator and instrument air compressor system and so on, the characteristics and realization of main functions, logic and control loop in RTU system are introduced.
