【摘要】：西气东输工程是具有战略意义的国家重点工程。实施西气东输工程,有利于促进我国能源机构和产业结构调整,带动东部、中部、西部地区经济共同发展,改善管道沿线地区人民生活质量,有效治理大气污染。西气东输一线的建设中关键核心设备——电驱压缩机组、燃驱压缩机组全部被国外厂商垄断。为了打破这一局面,二线的建设中,实现了20兆瓦级电驱压缩机组的国产化的应用。本论文以西气东输二线高陵压气站的首台套国产化20兆瓦电驱压缩机组的控制系统为研究对象,对国内外机组控制系统的发展概况、现状、发展趋势作了较为详细的介绍,并结合压缩机组所涵盖的所有需要控制的设备特点,设计出了整套机组的控制系统运行方案,对系统的软、硬件配置进行了详细阐述,全面论证了机组控制系统的设计、工作原理及硬件、软件相结合的工作机制。在本系统中,采用了罗克韦尔公司的Allen-Bradley ControlLogix 5000冗余控制系统作为下位机控制系统,监控部分采用W onderware公司生产的InTouch软件开发工具,组态了系统的监视与控制画面,并编制了相应的监控程序,使控制系统具备对机组过程数据的动态监控功能,实现了对机组的防喘振控制、负荷调节控制、顺序启／停机时序控制。另外,本文所论述的机组控制系统,已经交给用户使用。用户反馈的情况证实,该系统具有良好的可靠性和可操作性,控制方案的合理性到达甚至超过了同类国外机组控制,系统软件应用方便、灵活,受到用户的好评。
[Abstract]:The West-to-East Gas Transmission Project is a national key project of strategic significance. The implementation of the West-to-East Gas Transmission Project is conducive to promoting the adjustment of energy institutions and industrial structure in China and promoting the common economic development of the eastern, central and western regions. Improve the quality of life of the people along the pipeline, effectively control air pollution. The key core equipment in the construction of West-to-East gas transmission line-electric drive compressor. Combustion drive compressor units are monopolized by foreign manufacturers. In order to break this situation, the second line construction is in progress. The domestic application of 20 MW electric drive compressor unit is realized. The control system of the first set of domestic 20 MW electric drive compressor unit in Gaoling Gas Station of West East Gas Transmission Line 2 is the research object in this paper. The general situation, present situation and development trend of the control system of the unit at home and abroad are introduced in detail, and combined with the characteristics of all the equipments needed to be controlled by the compressor unit. The operation scheme of the control system is designed, the software and hardware configuration of the system is described in detail, and the design, working principle and hardware of the control system are demonstrated. Software working mechanism. In this system. The Allen-Bradley ControlLogix 5000 redundancy control system of Rockwell Company is used as the lower computer control system. In the monitoring part, the InTouch software development tool produced by W onderware company is used to configure the monitoring and control picture of the system, and the corresponding monitoring program is worked out. The control system has the function of dynamic monitoring to the process data of the unit, and realizes the anti-surge control, load regulation control, sequential start / stop timing control of the unit. In addition, the unit control system discussed in this paper. The user feedback has proved that the system has good reliability and maneuverability, the rationality of the control scheme reaches or even exceeds the control of the same kind of foreign units, and the system software is convenient to use. Flexible, by the user's praise.
