The Research On The State Detection Technology Of The Tram Super Capacitor Energy Storage System

At present, our country is at the stage of rapid development of urbanization, huge population into the city, the city public traffic caused very big pressure, the obtained the rapid development of urban rail transit, the trams as a form of urban rail transit has been rapid development.In August2013, China’s first fully modern streetcar line with independent intellectual property rights of network in shenyang muddy south district began operations, opened the car with China north of100%and100%low floor modern trams, and for the first time the super capacitor technology used to implement the crossroads of network, this paper studies the state of the super capacitor energy storage for the tram, super capacitor with long hours of use the performance may fall, once the performance degradation of super capacitor stored energy could not enough trams in the absence of the running of electric area, will cause the vehicle to stop in the area cannot be started without electricity, and even lead to line congestion and paralysis of the entire streetcar line, so, in this paper, aiming at this problem, design a tram energy storage system state detection devices, to test the super capacitor energy storage state, to determine whether a super capacitor stored energy enough through the area without electricity.This paper, based on the technology of shenyang muddy south tram operation parameters for reference, design calculation of the capacity of the super capacitor group, the main circuit of detection device and current transformer structure, energy storage inductor parameters and switch device selection, by method of contrast control system, finally choose the system voltage detection device of the outer ring, internal ring current double closed loop PI control adjustment. Using DSP chips and peripheral resources, development of detection device control system, designs the simulation of the sampling circuit and the software structure of writing. Finally through the MATLAB/Simulink software simulation of the super capacitor energy storage state detection, through to the super capacitor energy storage state detection of the simulation results analysis, completed the state detection of super capacitor energy storage system.
