【摘要】：随着船舶不断地向大型化与智能化的方向发展及电力推进等新技术在船舶上的应用,船舶用电设备越来越多,功率越来越大,船舶电力系统也变得越来越复杂。因此,对现代船舶电站管理系统提出了更高的要求,其监控和管理作用也就变得越来越重要了。高质量的船舶电站管理系统可以有效保证船舶电网工作的连续性和可靠性,其性能的好坏也将直接影响船舶航行的安全性和经济性。本研究在对国内外现有船舶自动电站控制装置进行研究和分析的基础上,结合实验室实际情况,设计并开发了一套船舶电站管理系统。本文设计的船舶电站管理系统以S7-200PLC为核心控制器实现该系统控制功能,上位机采用工业PC机,并利用WinCC组态软件进行界面设计以实现对船舶电站系统参数、状态和报警信息的显示以及远程操控,上位机与控制器之间采用PROFIBUS-DP通讯。本文详细阐述了船舶电站管理系统的工作原理及电力优化策略的选择,然后详细介绍了系统硬件选型,设计了各个功能的流程图,利用西门子STEP 7 MicroWIN V4.0进行PLC程序编写,实现了船舶电站管理系统的主要功能。本文还对上位机与S7-200PLC之间的PROFIBUS-DP通讯的实现过程进行了说明。在完成硬件连接及软件设计后,对系统进行了调试和试验,以确认该系统可以实现发电机组自动启停、自动准同步并车、自动调频调载、重载询问、发电机组保护等功能。实验结果表明,本文设计的船舶电站管理系统能够在实验室条件下稳定运行且实现了所设计的预定功能。
[Abstract]:With the continuous development of large and intelligent ships and the application of new technologies such as electric propulsion in ships, more and more electrical equipment and power are used in ships, and the power system of ships becomes more and more complex. Therefore, the modern ship power station management system has put forward higher requirements, its monitoring and management role has become more and more important. The high quality ship power station management system can effectively guarantee the continuity and reliability of ship power network, and its performance will directly affect the safety and economy of ship navigation. Based on the research and analysis of the existing marine automatic power station control devices at home and abroad, a set of ship power station management system is designed and developed in combination with the actual conditions of the laboratory. The management system of ship power station designed in this paper uses S7-200PLC as the core controller to realize the control function of the system. The upper computer adopts industrial PC, and the interface is designed by using WinCC configuration software to realize the parameters of ship power station system. Display and remote control of state and alarm information, PROFIBUS-DP communication between host computer and controller. In this paper, the working principle of ship power station management system and the choice of power optimization strategy are described in detail. Then, the hardware selection of the system is introduced in detail, the flow chart of each function is designed, and the PLC program is compiled by Siemens STEP 7 MicroWIN V4.0. The main function of ship power station management system is realized. The realization process of PROFIBUS-DP communication between host computer and S7-200PLC is also explained in this paper. After completing the hardware connection and software design, the system is debugged and tested to confirm that the system can realize the functions of automatic start and stop of generator set, automatic quasi-synchronous parallel operation, automatic frequency modulation and load adjustment, heavy load inquiry, generator set protection and so on. The experimental results show that the ship power station management system designed in this paper can operate stably in the laboratory and realize the designed function.
