【摘要】：目前,我国正处于城镇化的快速发展阶段,巨大的人口涌入城市,这对城市公共交通造成了非常大的压力,致使城市轨道交通得到了迅速的发展,而有轨电车作为城市轨道交通的一种也得到了飞速的发展。在2013年8月,我国的第一个完全拥有自主知识产权的现代有轨电车线路网络在沈阳浑南新区建成通车开始运营,该车采用中国北车集团开发的100%和70%低地板现代有轨电车,并第一次采用超级电容技术用来实现交叉道口的无网通过,在本文中,即针对有轨电车的超级电容器储能状态进行研究,超级电容器由于长时间的使用其性能可能会下降,一旦性能下降后超级电容器存储的能量就可能不够有轨电车在无电区的运行,就会导致车辆停止在无电区内无法启动,甚至导致线路拥堵和整个有轨电车线路的瘫痪,所以,本文针对这个问题,设计了有轨电车储能系统状态检测装置,对超级电容器的储能状态进行检测,判断超级电容器的存储能量是否足够通过无电区。本文根据沈阳浑南有轨电车实际运行的技术参数作为参考,设计计算了超级电容器组的容量,检测装置的主电路和变流器结构、储能电感参数和开关器件选取,通过控制系统方法的对比,最后选取对检测装置系统电压外环、电流内环的双闭环PI调节控制。利用DSP芯片和外设资源,开发检测装置的控制系统,设计了模拟采样电路和软件的编写结构。最后通过MATLAB/Simulink系统软件对超级电容器储能状态检测进行仿真,通过对超级电容器储能状态的检测的仿真结果分析,完成超级电容器储能系统状态检测。
[Abstract]:At present, our country is in the rapid development stage of urbanization, huge population is pouring into the city, which has caused great pressure on urban public transportation, resulting in the rapid development of urban rail transit. The tram as a kind of urban rail transit has also been a rapid development. In August 2013, China's first modern tram line network, with its own intellectual property rights, was opened to traffic in Shenyang's Hunnan New District, which uses 100% and 70% of the modern trams with low floors developed by the China North Rail Group. In this paper, the energy storage state of supercapacitors in trams is studied, and the performance of supercapacitors may decline due to the long time use of supercapacitors. Once the performance drops, the supercapacitor may not store enough energy to run the tram in the no-power zone, which can cause the vehicle to stop in the no-power zone and even cause congestion and paralysis of the whole tram line, so, In order to solve this problem, this paper designs a state detection device for the energy storage system of trolley cars, which detects the energy storage state of supercapacitors and determines whether the storage energy of supercapacitors is sufficient to pass through the no-current region. Based on the technical parameters of the actual operation of Hunnan tram in Shenyang, this paper designs and calculates the capacity of the supercapacitor bank, the main circuit and converter structure of the detecting device, the parameters of the energy storage inductance and the selection of the switch device. Through the comparison of the control system methods, the double closed loop Pi control of the voltage outer loop and the current inner loop of the detection device system is selected. The control system of the detection device is developed by using the DSP chip and peripheral resources. The analog sampling circuit and the structure of the software are designed. Finally, the energy storage state detection of supercapacitors is simulated by MATLAB/Simulink system software, and the simulation results of the energy storage state detection of supercapacitors are analyzed. Complete the state detection of supercapacitor energy storage system.
