摘要
针对现阶段电气化铁路的电能质量治理的现状提出在电气化铁路车站附近装设无功补偿装置对供电电能质量进行治理。提出了多重化SVG并联运行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,并在控制策略中引入了载波移相技术。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车站附近的供电电能质量的治理,而且载波移相技术的应用,提高了电力电子器件的等效开关频率,减少了SVG输出电流的谐波含量。仿真验证了文中设计方案的可行性和控制效果,有效提高了牵引供电系统车站附近的供电质量和稳定性。
The paper proposed electrification of the railway station 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. This paper presents a compensation scheme that SVG parallel operation multi and High voltage capacitor be used in conjunction, and the carrier phase shift be introduced in the control strategy technology. The paper used MATLAB / SIMULINK simulation software for modeling and simulation results show that the scheme can be able to achieve a good governance quality for the power supply station. And the introduction of carrier phase shift technology improved the equivalent switching frequency of the power electronic devices greatly. Simulation verified the feasibility of the paper and control results of the design, effectively improved the traction power supply system of power quality and stability.
