摘要
为更有效、更经济地解决传统V/v同相牵引供电系统中存在的电能质量问题,提出了一种在新拓扑结构下采用混合电能质量调节器(HPQC)的电能质量综合补偿方法。相比于传统拓扑结构下的补偿系统,新拓扑结构下的补偿系统有更加显著的节容特点。结合电气化铁道牵引负荷波动频繁的特性,对HPQC中无源器件(LC、L)和有源器件(变流器)的参数进行了设计。另外还分析了新型补偿系统下HPQC的控制策略,使其满足系统的补偿要求。
In order to effectively and economically solve the power quality problems in V/v co-phase traction power supply system,a compensation system based on HPQC(Hybrid Power Quality Compensator)under the new topology is proposed. Compared with the compensation system under the traditional topology,the HPQC under the new topology has more significant capacity-saving characteristics. The parameters of passive components(LC,L)and active components(converters)in HPQC are designed according to the intermittent railway demands. Moreover,the control strategy of HPQC under the new compensation system is analyzed,in which the requirement of the system compensation can be satisfied.
