【摘要】 船舶综合电力系统代表着当今船舶动力的发展方向,其主要特点是将推进系统与电力系统合二为一。世界各国已经有了综合电力系统原动机模块的系列化产品,但是还没有联合动力作为原动机模块的先例。由于燃燃联合动力装置具有机动性好,单位重量尺寸小等特点,所以把燃燃联合动力发电模块作为综合电力系统的一种模块来进行研究具有重要的工程意义。本文运用MATLAB/Simulink仿真工具对燃燃联合动力发电模块进行了建模与仿真,建模采用模块化的设计方法,整个系统包括燃气轮机模型、三S离合器模型、并车齿轮箱模型及电力系统模型。利用模型对单台燃机的动态过程,离合器的啮合过程,燃燃联合动力发电模块的并车、负荷转移、解列等动态过程进行了仿真研究。得到了不同升速率和不同阻尼下三S离合器中间滑移件位移仿真曲线,得到了燃燃联合动力发电模块单机及双机的各种运行模式下的转速、功率、电压、电流、频率以及并入和脱开时离合器中间滑移件的位移变化规律。燃燃联合动力发电模块的稳定可靠的运行关键是要求解决两燃机的功率分配问题。本文介绍了目前双机并车常采用的四种控制方式——并列调速器并车控制方式、主从调速器并车控制方式、平行式功率反馈调速器并车控制方式和单调速器并车控制方式的控制原理和各自的优缺点,对双机工作时负荷分配的方式进行了研究,找出了适合燃燃联合动力发电模块的运行方式并进行了仿真研究。更多还原

【Abstract】 On behave of the current development direction of Marine Power, Marine Integral Power System(IPS) is characterized by promoting the combining of the propulsion system and electric system. In the world, many countries have already had the series of products of the IPS motor module. But there is no precedent which using combined power plant as the motor module. Because The Combined gas turbine and gas turbine (COGAG) power plant has unique advantages such as good mobility and small weight, the research on IPS motor module using COGAG will have an important significance.Firstly, the power generation module was modeled and simulated with MATLAB/Simulink simulation tools in the dissertation. The system is comprised of the gas turbine model, SSS Clutch model, combination gear box model and electric system model based on the modular design. Secondly, the dynamic processes of the turbine, the mesh process of the Clutch, the combination、load transfer and breakaway of the COGAG generating electricity module were simulated. Finally, the displacement curve simulation of the 3S Clutch under the different rate and damping, the speed, power, voltage, current, frequency of the module for single and dual-mode and the displacement variety rule of sliding component when meshing and breaking were achieved.The power distribution of the COGAG is important for the stable and reliable operation of the COGAG generating electricity module. The control principle and the advantages and disadvantages of four control modes——joint operating control method of multiple speed controller, master slave speed controller, parallel speed controller with feedback power and single speed controller which were always adopted in the combined twin-engine at present are introduced in this dissertation. The load distribution approaches were studied. A suitable operation mode for the COGAG generating electricity module was obtained and was also simulated.更多还原
