【摘要】：课题在对海上石油平台控制系统架构进行深入分析的基础上,结合海上平台自动化控制系统的需求,完成了海上平台自动化控制系统的的设计、组态与开发,并对控制系统存在的典型问题,即流程控制问题和设备控制问题,分别提出了可行的改进方法。论文首先分析了海上石油平台自动化控制系统的必要性和重要性,介绍了罗克韦尔自动化公司提出的Net Linx三层网络构架、ControlLogix系统以及Rockwell软件平台。三层网络构架分别是基于DeviceNet的设备层、基于ControlNet的控制层和基于Ethernet/IP的信息层。Rockwell软件平台主要由编程软件、网络组态、通信驱动及监控软件构成。进而分析了海上平台控制系统架构形式,结合平台对控制系统的需求,对海上平台自动化控制系统的总体方案的进行了设计。在此基础上,对整个海上石油平台控制系统中的三个子系统——过程控制系统、应急关断控制系统以及火灾和可燃气探测控制系统,分别从网络系统构架、PLC控制程序的开发以及人机化界面的设计进行了详细的介绍。结合现场实际生产情况,论文的最后针对控制系统存在的典型控制问题,即流程控制问题和设备控制问题,在深入分析的基础上提出了可行的改进方法,提高了控制系统的可靠性和稳定性。最后通过功能测试和性能测试两个角度,全面测试了系统功能。课题研究的成果不仅提高了海上平台的生产效率、人员的安全性和对海洋环境的保护,同时为渤海油田近期海上急需自动化控制系统改造的平台提供了借鉴。
[Abstract]:Based on the deep analysis of the structure of offshore oil platform control system and the requirements of offshore platform automation control system, the design, configuration and development of offshore platform automation control system are completed. Some feasible improvement methods are proposed for the typical problems of the control system, namely, the flow control problem and the equipment control problem. Firstly, this paper analyzes the necessity and importance of the automatic control system for offshore oil platform, and introduces the Net Linx three-layer network architecture, ControlLogix system, and the Rockwell software platform proposed by Rockwell Automation Company. The control layer based on ControlNet and the information layer. Rockwell software platform based on Ethernet/IP are mainly composed of programming software, network configuration, communication driver and monitoring software. Furthermore, the architecture of the offshore platform control system is analyzed, and the overall scheme of the offshore platform automation control system is designed according to the platform's demand for the control system. On this basis, three subsystems in the whole offshore oil platform control system-process control system, emergency shutdown control system, fire and gas detection control system, The development of PLC control program and the design of human computer interface are introduced in detail. According to the actual production situation in the field, in the end of the paper, aiming at the typical control problems existing in the control system, that is, the flow control problem and the equipment control problem, the feasible improvement methods are put forward on the basis of in-depth analysis. The reliability and stability of the control system are improved. Finally, the function of the system is tested from two aspects: function test and performance test. The research results not only improve the production efficiency of offshore platform, safety of personnel and the protection of marine environment, but also provide a reference for the platform which is in urgent need of the transformation of offshore automatic control system in Bohai Oilfield in the near future.
