基于MMC的铁路再生制动能量回收装置的研究
|
摘要
模块化多电平换流器(modular multi-level converter,MMC)现已成为最具前景的多电平技术。分析了基于MMC的整流逆变装置的工作原理及拓扑结构,研究了一套基于MMC的电气化铁路再生制动能量回收装置。装置在完成制动能量回收的同时,节省了匹配变压器成本。讨论了参数选择和整流逆变环节的控制策略。最后通过仿真验证了基于MMC的电气化铁路再生制动能量回收装置的可行性和有效性。
Modular multi-level converter( MMC) has become the most prospective multi-level technology. This paper analyzed the working principle and topological structure of a MMC-based rectifier-inverter,and explained a MMC-based regenerative braking energy recovery device for electrified railways. The proposed device could not only recover the braking energy,but also save the cost of the matching transformer. Furthermore,it discussed parameter selection and the control strategy for the converter-inverter. Finally,simulation results verified the feasibility and validity of the MMC-based regenerative braking energy recovery device for electrified railways.
