摘要
针对现有牵引网调压方案无法从根本上提高接触网端电压、调节能力有限和动态性能差的缺点,提出了一种结构简单、响应速度快、调压效果好的基于晶闸管控制串联变压器的自动调压解决方案,并对此方案的实现原理、电路拓扑结构和控制策略进行了设计,在此基础上给出了流程图,最后给出了采用DSP的控制器设计方案。
In view of the problem that former regulations can＇ t rise the voltage of contact net radically and have the limit of regulating capacity and dynamic performance, thyristor controlled serial transformer （TCST） voltage regulator based on DSP that has fast response and good regulation results is presented. The principle, circuit topology, regulation strategies are also investigated. On this basis, the control flow chart and the design of the DSP controller is proposed.
