摘要:
随着轨道交通车辆对变流装置体积及重量要求的不断提高,大功率电力电子牵引变压器(PETT)是高速列车牵引传动系统小型化、轻量化的发展方向之一。文章提出了一种25 kV 单相供电PETT 电路拓扑结构,采用谐振PR 控制器实现网侧单位功率因数运行,并提出基于模块电压排序法原理实现每级电容电压及输出功率自适应均衡控制策略。通过搭建25 kV/4.5 MVA 单相电力PETT 的PSIM 仿真系统,验证了所提电路拓扑及自适应均压算法的有效性,并对网侧电流谐波含量进行分析。
Abstract:
With the growing requirments of size and weight of converter in rail transit, high-power vehicle power electronic traction transformer(PETT) is one option to meet the miniaturization and lightweight trend of traction and driving system in high speed train. In this paper, topology of the power electronic transformer circuit for 25 kV single-phase power supply system was designed. Resonant PR controller was used to realize the unit power factor operation, and adaptive equalization control strategy of capacitor voltage and output power were realized based on the module voltage ranking method. Effectiveness of the proposed circuit topology and adaptive voltage equalization algorithm were verified by constructing the PSIM simulation system of 25 kV/4.5 MVA single-phase power electronic traction transformer, and the harmonic of the network current was analyzed.
