先进的交流电传动现状和展望

Modern AC Drive Technology-State of the Art and Innovations

始于上世纪70年代初的交流电传动技术已经从晶闸管技术发展到GTO技术。交流电传动技术的不断成熟,使其真正成为所有新机车动车的标准。在最近几年中实现了IGBT取代GTO晶闸管的重要技术转型。作为最新进步,该技术转型现在还涵盖了大功率应用范围。德国铁路公司新型的BR189四电流制电力机车最早将该项革新技术应用于极限功率范围。新的交流传动调节方法SITRAC融合动力学、耐用性和具有自调节的最佳调制为一体,其运行可不用速度传感器。展望未来以及铁路工业试验室不断加强对超导变压器、静态能量储存、无传动齿轮箱的直接传动和燃料电池的前景的关注,这里不仅是考虑能源价格的日益增涨。预计在2010年前一些革新技术将用于铁路中。

Starting at beginning of the seventies of the last century the three-phase ac drive technology was developed from Thyristortechnology to GTO technology. With its high maturity three-phase ac drive technology has become the standard for practically all new vehicles.During the last years the replacement of GTO-Thyristors by IGBTs (insulated gate bipolar transistor) was carried out as another importanttechnology change. Now as the last step this technology change also covers the high power applications. The new class 189 four-systems-locomotive of German Rail (DB AG) forms the leading application for this innovation in the high power range.The new three-phase drive control strategy SITRAC combines dynamic torque control, robustness and optimized modulation withselfadjustment and allows speed sensorless operation. With the superconducting transformer, with static energy storage systems, with gearlessdrive systems and fuel cells a view to the future and the labs of the railway industry shows interesting visions not only in regard to rising costs forenergy. Therefore, some of these innovations will be introduced in railway applications still in this decade.
