摘要

电气化铁路的建设

能够有效地节约资源、降低环境污染

带动了国民经济发展。但也给电力系统来了许多危害

比如谐波、负序、无功等

影响电网的供电质量以及稳定运行。针对牵引供电系统电能质量问题

本文提出基于电铁能量调节器的补偿原理。建立了基于Scott变压器的无功、负序补偿数学模型

在此基础上设计了电铁能量调节器基于dq坐标的稳态模型及相应的控制器

该模型实现了有功、无功进行解耦控制。利用Matlab/Simulink仿真软件

对本文所提出的无功、负序补偿策略进行了仿真分析

仿真实验结果验证了控制系统的优越性。

Abstract

The construction of electric railway can save resources effectively

reduce environmental pollution anddrive developmentofthenationaleconomywhich

however

brings many such harm to the power system asharmonic

negative sequence and reactive power etc. and affects power supply quality and stable operation of the grid. Aiming at power quality problems in traction power supply system

a compensation principle based on railway power conditioner is proposed in this paper. The mathematical model for reactive power and negative sequence compensation based on Scott transformer is set up. On this basis

the steady-state model of railway power conditioner based on dq-axis and corresponding controller is proposed. The model achieves active and reactive power for decoupling control. The reactive power and negative sequence compensation strategy proposed in this paper are simulated and analyzed by the use of Matlab/Simulink softwareandthesuperiorityofthecontrolsystemisverifiedbythesimulationandexperimentalresult.
