摘要
介绍了双向变流器的原理、设备组成和试运行情况。试验证明双向变流器同时具有整流、逆变双向变流能力及无功补偿功能,并具有良好的可靠性。分析了双向变流器的应用模式,认为该设备应用后可以改变目前城市轨道交通牵引供电设备的组成模式,提升供电品质,同时还可以影响到多个相关专业,在一定程度上改变城轨交通工程技术的面貌。
This paper introduces the principle,equipment composition of bi-directional converter and it＇s trial run.Test proves that the bi-directional converter has the functions such as rectifying,inverting and reactive power compensating by the same converter,and has a good reliability.This paper briefly analyzes the application model of bi-directional converter,and believe that applied in the urban railway traction power-supply system,it will change the composition of system,and improve the power supply quality.At the same time,it can affect multiple related systems,and to a certain degree change the outlook of urban railway traffic engineering technology.
