| 摘 要： | 随着电气化铁路在铁路运输中所占比重的不断增大和电压等级的不断提高,电气化铁路牵引负荷对电网的影响也随之增大。为了建立准确有效的电气化铁路牵引负荷模型以评估其对系统的影响程度,文中根据建模策略,从负荷实测数据出发,并结合生产实际,对电气化铁路牵引负荷建模中实测数据的选取进行了分析,提出了电气化铁路牵引负荷测量时的电流突变量启动录波判据,并在实际电网中得到验证,为电气化铁路实测负荷建模提供了数据支持。

| Abstract: | With increasing percentage of the electric railway in railway transport system and upgrading of the voltage level,the influence of traction load of electric railway on power grid becomes more and more great.To establish accurate and effective traction load model for electric railway in order to evaluate the influence degree on system,analysis of the measuring-data selection of load modeling for electric railway is carried out by combining practice based on modeling strategy from the view of load measuring data.In addition,the criterion of start-up data recording of current break variable for traction load measurement of electric railway is proposed,and it is verified in practice power grid,which provides the data support for measuring-data based load modeling for electric railway. |
