摘要
为了研究电气化机车运行中公共电网的电能质量,依次对电气化铁路的牵引网、牵引变电站、AT所和电力机车建立了仿真模型。基于扩展Prony法,利用数学形态学滤波器滤除周期性脉冲噪声,并对信号进行分析,结果表明,基于数学形态学滤波的扩展Prony法能够很好地克服自身对噪声敏感的缺陷。
In order to analysis the power quality of power grid which is affected by electric locomotive, the simulation models of electric railway traction, traction substation, AT and electric locomotives are founded. Based on the effec- tiveness of extended Prony, the mathematical morphology filter is used to remove the periodic pulses in the signal and then the signal is analyzed. The result shows that the extended Prony based on mathematical morphology filter method can overcome its deficiencies on noise-sensitive.
