基于SVG的电气化铁路动态无功补偿方案的研究

本文针对现阶段电气化铁路的电能质量治理的现状,提出在牵引变电所增设无功补偿装置对供电电能质量进行治理,提出了SVG与高压电容器组配合使用的补偿方案,设计了SVG的控制策略。应用MATLAB/SIMULINK软件进行了建模仿真,仿真结果表明本文所设计的方案能够很好地实现对牵引供电系统的供电电能质量的治理,仿真验证了文中设计方案的可行性和控制效果,该方案能效提高了牵引供电系统供电质量和稳定性。

The Research of Electrified Railway Dynamic Reactive Power Compensation Scheme Based on SVG

The paper proposed electrification of the traction substation in the vicinity of the installation of reactive power compensation device for power quality of governance based on the status at this stage electrified railway power quality of governance. The paper proposes a compensation scheme SVG be used in conjunction with high-voltage capacitor bank and designed control strategy of SVG. The paper used MATLAB/SIMULINK software for modeling and simulation results show that the scheme can be able to achieve a good governance quality for the traction power compensation. Simulation verified the feasibility of the paper and control results of the design. The program can effectively improve the traction power supply system power quality and stability.
