摘要
电气化铁路负荷易对电网母线造成较严重的电能质量污染,有必要通过建模分析。作为2篇系列文章的第2篇,在第1篇文章的建模基础上,重点对电气化铁路可能出现的不同类型列车在不同工况运行时对变电站母线电能质量的影响进行了对比分析,即:分别针对电气化铁路无车、有1辆客车运行、有1辆货车运行和有2辆货车运行的4种典型工况,针对电气化铁路运行对220 kV三相母线电压波动、谐波、三相不平衡的影响进行了仿真对比。
Considering that electrified railway load easily brings about serious power quality pollution for the power grid buses,it is necessary to give analyses through modeling. As the second part of the two-part paper,on the basis of the established model introduced in the first part,the influences of different electrified railway’s operations on the power quality of bus bar in substation were analysed and compared,that is,focusing on the four conditions that the railway has no vehicle,one running passenger vehicle,one running truck and two running trucks. Simulation comparison on the impact of the running electrified railway on the voltage fluctuations,harmonics and three-phase unbalances of the 220 kV three phase bus bar was given.
