武广客运专线铁路电力负荷特性分析及预测

Power load characteristics analysis and forecast of Wuhan-Guangzhou electrified passenger railway

武广客运专线铁路牵引负荷具有负荷随机波动、在制动时向电网注入功率、全天存在充电无功等特点。通过分析牵引负荷数据,得到了不同运行图下的牵引负荷特性和数据分布特征,提出了武广高铁冲击负荷的预测方法,为湖南全省负荷预测和调度实时控制性能评价标准(control performance standard,CPS)提供了依据。

Wuhan Guangzhou electrified high-speed railway has some characteristics , such as stochastically fluctuant traits of traction load , felling power into power system when braking and felling reactive power into power system all the day. In this paper , through the statistics and research on quantities of test data of traction loads , some basic characteristic parameter and probabilistic distribution characters of traction loads for different operation plan are obtained and the forecast method is opposed for traction load.It will be a useful guidance to forecast the traction load and to adjust CPS in real time.
