|
摘要
为解决高速、重载铁路V/v牵引变压器供电系统功率因数低、负序高、高次谐波污染等电能质量问题,提出了一种新型电能质量治理装置,分析了其电气拓扑结构及工作原理,研究了级联H桥均压和补偿电流实时跟踪控制方法及基于能量平衡的双主动桥功率控制策略,并通过仿真验证了该装置拓扑结构及控制策略的可行性和优越性。
In order to solve the power quality problems of low power factor, high negative sequence and high order harmonic pollution in traction transformer power supply systems for high speed and heavy haul electrified railways, the paper puts forward a new type of power quality control device, analyzes its electrical topological structure and working principles, studies the cascaded H bridge voltage equalizing and compensated current real time tracking and control method as well as the energy equalizing based dual active bridge power control strategy. The feasibility and advantages of the topological structure and control strategy of the device have been verified by means of simulation.
