摘要:
［目的］我国城市轨道交通线路传统的牵引供电系统大多采用二极管整流机组，该方式存在电能只能单向流动、再生制动能量无法回馈到供电系统等问题。可有效解决此问题的基于IGBT(绝缘栅双极型晶体管)的双向变流装置已研制成功，并有应用案例。为了促进双向变流技术的进一步发展，需了解双向变流装置的研究进展。［方法］阐述了双向变流装置特点，整流/逆变双向变流技术概要及双向变流能量综合管理系统构架。分析了双向变流装置在国内外的应用现状，阐述了2个电压控制策略(恒压控制策略、下垂控制策略)的直流电压、电流输出外特性。介绍了既有的潮流计算算法，探讨了含双向变流装置的城市轨道牵引供电系统的算法要求。［结果及结论］双向变流装置在城市轨道交通供电系统中的成功应用，实现了列车的再生制动能量回馈，提高了整个供电系统的运行效率。
Abstracts:
［Objective］ Most of the traditional traction power supply systems of urban rail transit lines in China use diode rectifier units, which have the deficiencies that electric energy can only flow in one direction and the regenerative braking energy can not be fed back to the power supply system. The bidirectional converter based on IGBT (insulated gate bipolar transistor) is successfully developed and applied in actual cases. In order to promote the further development of bidirectional converter technology, the relevant research progress needs to be studied. ［Method］ The characteristics of bidirectional converters, rectifier/inverter bidirectional conversion technology, and the integrated management system architecture of bidirectional conversion power are described. The status quo of bidirectional converter application in China and abroad is analyzed, and the DC voltage and current output characteristics under two voltage control strategies i.e. constant voltage control strategy and droop control strategy, are expounded. The existing current calculation algorithms are introduced, and the algorithm requirement of the urban rail traction power supply system with bidirectional converters is discussed. ［Result & Conclusion］ The successful application of bidirectional converters in urban rail transit power supply system realizes the train regenerative braking energy feedback, improving the operation efficiency of the whole power supply system.
