摘要
为实现对电气化铁道无功和负序的补偿,提高系统电能质量,提出一种基于混合型电气化铁道电能质量综合治理系统H-RPQMS(hybrid railway power quality management system)的综合控制方案。H-RPQMS的变流系统由2个背靠背变流器构成。在两相静止坐标系和旋转坐标系下分别建立了H-RPQMS的数学模型,分别设计了两个变流器的电压外环和功率外环以及电流内环。通过Matlab/Simulink仿真验证了该控制方案的有效性。
To improve the power quality of electrified railway by the compensation of reactive power and negative sequence, a comprehensive control scheme based on a hybrid railway power quality management system (H-RPQMS) is proposed in this paper. The inverter system of H-RPQMS is composed of two back-to-back converters. The mathematical models of H-RPQMS in the stationary reference frame and rotation reference frame are established, respectively. The outer DC-vohage loop and outer power loop are designed for the two converters separately, together with the corresponding inner current loops. Finally, the effectiveness of the proposed control scheme is demonstrated by simulations based on Simulink of Matlab.
