摘　　要：针对大型压水堆核电站核燃料换料机存在的缺陷,结合大亚湾核电站和岭澳核电站的实际运行经验,对核燃料换料机控制系统进行了研究。引入技术成熟、先进的Devicenet总线网络,以单一故障原则为基础,将整个控制系统围绕一套以太网络和两套Device-net总线网络来设计,并将双网络进行融合,构建了核燃料换料机的新控制系统。新控制系统应用了成熟的新技术、新设备,解决了以太网和单套PLC不满足单一故障原则的重大缺陷,提高了核燃料换料机装卸核燃料组件的安全性和整体性能,并使控制系统接线简单、通讯稳定。根据新控制系统设计的核燃料换料机已经成功应用于大亚湾核电基地培训中心和广西防城港核电站,取得了明显的应用成效。In order to solve the disadvantages of the Nuclear Fuel Manipulate Crane(ab.MC),the control system of MC is researched and designed,which is based on the operation experiences about PMC in Daya Bay and Ling'ao Nuclear Power Plant.The new control system adopts single failure principle and makes use of the Device-net technology that is diffusely applied and extraordinary tried in practice.There are two Device-nets and one Ethernet,the two kinds of nets are combined.Applying the new technologies and new equipments,the new control system solves the defects which Ethernet and a single set of PLC don't satisfy single failure principle,improves the safety and whole performance of MC loading and unloading of nuclear fuel assembly,and makes control system simply to wire.According to the design of the new control system,the product of MC has been successfully applied to Educate Center in Daya Bay Nuclear Power Site and Fangchenggang Nuclear Power Plant,the results is obvious.
