项目摘要

Since 1960s regenerative trains have been introduced on private railways and now they are popular to Japan Railways Group as well. The purpose of this research is reassessment of power feeding system design and control of regenerative trains.(1) Design and Control of DC Feeding System with Regenerative Trains.In order to reduce the probability of non-receptive line condition, where trains can not use regenerative braking resulting more energy consumption and more braking pad wear, the follwing effective countermeasures have been sought: Reduction of no-load output voltage of substations or increase of maximum allowable system voltage, constant voltage control or better voltage regulation of substation output voltage, or reduction of feeder circuit resistance.(2) Design and Control of AC Feeding System with Regenerative Trains.Contrary to the dc feeding system in which all substations are connected in parallel, ac feeding system is normally fed by only one substation in order to keep fr … More om circulating current among substations. At the boundary section of different substations, power flow to or from the train is therefore discontinuous which prevents a braking train from continuous regeneration. To cope with this circumstance, the follwing promising means ahve been obtained; changeover with short time paralleling, instantaneous changeover. Changeover with short time interruption, and rheostatic section whose intermediate section is connected solely to a rheostat, corresponding to the sectioning system, control scheme of the traction converter have been developed; phase control of the converter which prevents the main transformer from being asymmetrically magnetised or where the phase of regenerating voltage changes smoothly from that of one source to another.(3) Current Beat and Torque Ripple Suppression Control of Pulse Width Modulated (PWM) AC Regenerative Trains.A novel control method of traction inverter has been developed. The traction inverter with pulsating input voltage due to single phase rectification produces muchd current beat and torque ripple which are harmful to train operation. A sophysticated waveform which suppresses these adverse effects has been successfully obtained. Less

自20世纪60年代以来，再生列车已被引入私人铁路，现在它们也受到日本铁路集团的欢迎。本研究的目的是重新评估的供电系统的设计和控制的再生列车。(1)再生列车直流供电系统的设计与控制为了减少非接受性线路条件的概率，即列车不能使用再生制动，导致更多的能量消耗和更多的制动垫磨损，已经寻求以下有效的对策：变电站空载输出电压降低或最大允许系统电压升高，变电站输出电压的恒压控制或更好的电压调节，或馈线电路电阻的减小。(2)再生列车交流供电系统的设计与控制与直流供电系统不同，交流供电系统通常由一个变电站供电，以保持系统的可靠性。 ...更多信息防止变电站间的环流。因此，在不同变电站的边界区段处，去往或来自列车的功率流是不连续的，这阻止了制动列车的连续再生。科普这种情况，提出了短时间并列切换、瞬时切换等有前途的方法。与分段系统相对应的短时中断转换和中间部分仅连接到变阻器的变阻部分，已经开发了牵引转换器的控制方案;转换器的相位控制防止主Transformer不对称磁化或再生电压的相位从一个源平滑地变化到另一个源。(3)PWM交流再生列车电流拍频和转矩涟漪抑制控制提出了一种新型的牵引逆变器控制方法。牵引逆变器输入电压脉动时，单相整流会产生较大的电流拍频和转矩涟漪，对列车运行产生不利影响。已经成功地获得了抑制这些不利影响的sophysticated波形。少
