摘要

为解决电气化铁路牵引供电系统中三相网侧谐波、无功和负序等电能质量问题

同时满足电气化铁路补偿容量大的要求

提出了采用并联型铁路功率调节器（railway static power conditioner

RPC）配合降压变压器的综合补偿方案

具体研究了并联型RPC的控制策略并进行了仿真分析。提出了对RPC的指令电流检测采用平衡补偿电流检测法

对RPC的补偿电流控制采用基于比例谐振（proportion resonance

PR）控制器的三角波比较控制方式

同时将载波相移（carrier phase shift

CPS）技术应用于RPC的控制。最后

利用MATLAB/Simulink搭建了由2个RPC并联构成的补偿方案的仿真模型。仿真结果表明:RPC投入运行后

三相网侧电流为与电网电压同相位的三相正弦对称电流

只含有开关频率整数倍次的高次谐波;通过进一步采用CPS技术

开关频率奇数倍次的高次谐波被有效滤除

三相网侧电流总谐波畸变率由8.04%降低为2.24%。仿真结果验证了并联型RPC在解决牵引供电系统中三相网侧电流谐波、无功和负序等电能质量问题方面的可行性与优越性

为并联型RPC的工程应用提供了有价值的参考。

Abstract

In order to solve the power quality problems

such as harmonic

reactive power

and negative sequence in the three-phase line side of the electrified railway traction power supply system

and to meet the needs of heavy compensation capacity of the electrified railway

a comprehensive compensation scheme

which was formed by the railway static power condition（RPC） and the step-down transformer

was proposed

and the control method of the parallel RPC was specifically researched. The balanced compensation current detection method was used in instruction current detecting and triangle wave comparison of proportion resonance（PR） controller was used in compensation current controlling. Also

the carrier phase shift（CPS） technology was applied in RPC controlling. At last

the modeling and simulation of the compensation scheme which was composed of two parallel RPC were built on the MATLAB/Simulink. The simulation results show that the three-phase line side currents will keep balanceable after one fundamental frequency cycle when RPC has been put in operation. By adopting the CPS technology further

the three-phase line side currents total harmonic distortion rate is reduced from 8.04% to 2.24%. The research work here confirms the feasibility and superiority of the parallel RPC for solving the power quality problems in the three-phase line side of the traction power supply system

and also provides a valuable reference for the engineering application of the parallel RPC.
