LNG船液货系统的集成控制是LNG船的关键技术之一.由于LNG具有极低温、高膨胀性、可燃性的潜在危险性,因此,LNG船和一般船舶相比,其复杂性高,对其安全性和各项指标的要求高.分析了LNG船液货控制系统,提出了基于DeltaV系统和MIMIC系统的LNG船液货集成控制系统的仿真平台方案.基于此仿真平台,以压载系统为例,说明了控制逻辑的仿真方法和仿真平台的有效性.%The integrated control of LNG liquid system is one of the key technologies of LNG carrier. This article analyzed the LNG liquid system and set up a simulation platform for the integrated control of LNG carrier liquid system based on Emerson's DeltaV system and Mynah' s MIMIC industrial simulation system to verify the accuracy of liquid system control strategy. Based on the platform,the simulation of the ballast system was realized.
