摘要
牵引变电所群贯通供电系统可有效解决交流电气化铁路电分相问题,然而该系统存在三相电压不平衡。针对该系统三相电压不平衡问题,提出了一种基于潮流控制器的负序集中补偿方案。该方案可实现对所群供电系统的负序集中补偿,且兼顾无功补偿。首先,介绍了所群供电系统及该方案补偿装置的拓扑结构;然后,阐述了该方案的负序、无功补偿原理,分析了补偿装置计算容量的变化规律;最后,采用Matlab/Simulink仿真实验平台,结合两牵引变电所实测数据进行仿真,验证了该方案的可行性及有效性。
The interconnected power supply system of traction substation group effectively addresses the phase separation problem of AC electrified railways,but this system presents three-phase voltage unbalance.To tackle this problem,a centralized negative sequence compensation scheme based on the power flow controller is proposed.This scheme enables centralized compensation of the negative sequence for the interconnected power supply system of interconnected power supply system of the traction substation group while considering reactive power compensation.The topological structure of the compensated device in this scheme is introduced.The negative sequence and reactive power compensation principles are elaborated,and the variation in calculated capacity of the compensation device is analyzed.The effectiveness of the scheme is validated through simulation experiments using the Matlab/Simulink simulation platform.
