为了适应我国铁路运输市场的需求,国家大力发展铁路建设,特别是客运专线的建设。但是我国还没有客运专线的修建经验,牵引供电系统是客运专线一个重要的组成部分,是否要在牵引变电所设置无功和谐波补偿装置,将直接影响客运专线的建设成本。本文通过对谐波含量和电压畸变率的分析以及对牵引变电所一次侧平均功率因数的仿真估算,来确定是否要在牵引变电所设置无功和谐波补偿装置。
In order to meet the demand of China’s railway transportation market, the state has made great efforts to develop railway construction, especially the construction of passenger dedicated lines. However, there is no construction experience of passenger dedicated line in our country. The traction power supply system is an important part of passenger dedicated line. Whether to set reactive power and harmonic compensation device in traction substation will directly affect the construction cost of passenger dedicated line. In this paper, through the analysis of harmonic content and voltage distortion rate and the simulation of the average power factor of the primary side of the traction substation, it is determined whether to set reactive power and harmonic compensation device in the traction substation.
