【摘要】 随着现代造船技术的发展,船舶对电站管理系统的可靠性和经济性要求越来越高,因此船舶电站的控制、监视和管理的重要性显得越来越突出。本论文在对现有的国内外船舶电站自动控制装置进行充分研究和分析的基础上,基于可编程控制器(PLC)、先进的工业控制技术和计算机技术设计了一套集散式船舶电站管理系统。本文设计的电站管理系统由一个主站和三个子站组成。主站计算机是以Windows XP作为操作系统的工业PC控制机,使用图形操作界面实现数据采集、查询、显示、记录等功能。每个子站由一台S7-300 PLC构成,独立控制一台发电机组,子站S7-300 PLC进行数据检测和控制。利用西门子公司的编程软件Step7设计了PLC控制程序,实现了电站的综合控制功能,主要设计了自动起动模块、自动准同步并联运行模块、自动调频调载模块、自动解列模块和自动停机模块等。本文利用Simatic Net、Step7、WinCC等软件和Profibus总线实现了工业PC控制机和S7-300 PLC之间以及三个S7-300 PLC之间的通讯。根据船舶电站管理系统的控制功能和操作规范,并利用WinCC进行了工业PC控制机监控单元的设计。最后通过模拟试验,验证了基于可编程控制器(PLC)设计的集散式船舶电站控制系统运行的可靠性和经济性。更多还原

【Abstract】 With the development of modern shipbuilding technology, the requirement for reliable ship power management system is more and more necessary. Therefore, controlling, monitoringand follow-up managing of ship power are more and more important. Based on the sufficient research and analysis on current domestic and overseas ship auto-control equipment, I designed a total distributed ship power management system by using the programmable controller, advanced industrial controlling technology and computer technology.The ship power management system is composed of an operating station computer and three slave computers. Master computer (operation station computer) is composed of an industrial PC with Windows XP as the operating system. Using graphical user interface, master computer has data capturing, displaying, recording and relevant data enquiring functions.Every slave computer, cored by Siemens S7- 300 PLC, controls a generator independently. Slave computers have data detection and data control function. We designed the program of PLC by using the Siemens’ program software (Step7) to realize the surveillance function of the ship power station. Auto-start module, automatic quasi-synchronous parallel operation module, automatic frequency and load regulation module, automatic parallel off module and automatic-stop module are designed.The master computer and slave computers are communicating through the software of Simatic Net, Step 7 and WinCC and Profibus field-bus. Acording to the control function and operation rules of ship power management system, this paper has designed the monitoring software of PC, using the configuration software WinCC.Finally, the simulation test verifies the reliability and economic effect of the total distributed ship power management system based on the programmable controller.更多还原
