摘要
伴随着社会发展需求,电气化铁路在国民经济中所占比重越来越大,促进了经济的发展,但给公共电网带来的谐波、无功和负序电流问题也日益凸显。围绕着上述问题,国内外开展了很多研究。针对国内外相关研究和所取得的成果,阐述目前电气化铁路牵引供电系统存在的问题及各种解决方案,对各种解决方案的优势和不足进行归纳总结,并进行了分类,提出无牵引变压器新型同相供电系统的实现思路及关键控制技术,为同相供电的理论研究和实际应用提供参考。
Accompanied by social development needs, electrified railway proportion in the national economy is growing. It promotes not only the development of the economy, but also the public grid harmonics, reactive power and negative sequence current problems. Around these problems, a lot of studies carried out at home and abroad. In view of the related research and achievements, explained the existing problems and solutions, summarized and classified the advantages and disadvantages of all kinds of power supply scheme, proposed the idea and the key of the realization of the new co-phase power supply technology without traction transformer, provides reference for the research and application of co-phase power supply.
