Evaluation of Safety and Reliability of Pure Electric Rrake

新庆成铁路采用再生式制动有效下至完全停车，实现了纯电动制动的第一步。但在这一应用阶段，常规的摩擦制动器也常用于正常运行。这意味着这项研究比以前更加重要，因为真正的纯电动制动器有望在不久的将来推出，其中所有的工作制动器都是在电气模式下制造的。在三年的研究周期中，前两年主要讨论了由于缺乏附着力和电源电压波动等各种原因可能导致的超限对策，最后一年的讨论范围扩大到馈电系统的能力、相互关联列车的运行、速度和接触网电压的再生性能。本研究的最终报告已被编辑，不仅包括三年科研资助的结果，而且还包括以前的研究结果，以便许多希望引进纯电动制动的铁路工程师能够方便有效地使用报告。最后报告各章节的标题如下：介绍纯电动制动的步骤；2 .实现电动刹车完全停止；再生模式下电制动的确定性和可靠性；再生损失对策；5 .采用纯电动制动器提高性能；纯电动制动能力的实际制约因素，7。8.防滑措施；9.检测速度和位置的粗糙度和误差的对策。高速区域再生性能的限制及特性的有效利用，10。机动车辆与可用减速比，11。提高高速区域再生的方法，12。列车部分自动化操作提高列车性能的建议，13。协助手动操作以提高列车性能。纯电动制动视角。少

The first step of pure electric brake has been realised by adopting regenerative mode braking effective down to complete stop on Shin-Keisei Railway line followed by many other railways. But in this stage of application, conventional friction brake is often used in normal operation as well. This means that this research has been more important than before because real pure electric brake, in which all service brake is made in electrical mode, is expected to be introduced in near future.In first two years out of the three year research period, major discussion of countermeasure against possible overrunning due to various reasons such as lack of adhesion and source voltage fluctuation was completed and so in the final year, scope of discussion has been widened to ability of feeding system, operation of mutualy related trains, performance of regeneration against velocity and catenary voltage, and ratio of number of motor cars to trailers etc.The final report of this research has been edit … More ed to include not only the results of the three year period by grant-in-aid for scientific research but also those of former researches in order for many railway engineers, who would like to introduce pure electric braking, to use the report easily and effectively. The titles of the chapters of the final report are as follows:1.Steps of introducing pure electric braking,2.Realisation of electric brake down to complete stop,3.Certainty and reliability of electric brake in regenerative mode,4.Countermeasure for loss of regeneration,5.Improvement of performance by pure electric brake,6.Actual restricting factors of ability of pure electric braking,7.countermeeasure against skidding,8.countermeasure against roughness and errors in detecting velocity and position,9.Restriction of regenerative performance in high speed region and effective use of the characteristics,10.Ratio of motor cars and available deceleration,11.Methods of improving regeneration in high speed region,12.Proposal of partly automatic train operation to improve train performance,13.Assistance to manual operation to improve train performance14.Perspective of pure electric braking.
