基于电力系统负荷建模基础理论和电气化铁路系统结构,建立一种电气化铁路冲击负荷模型.对实测电气化铁路冲击负荷的负荷曲线进行小波分析法去噪并用作模型参数辨识.面向电网PCC点建立交直型和交直交型电力机车的综合负荷特性模型,形成电气化铁路冲击负荷模型结构.制定模型参数辨识策略并加以实施.针对冲击负荷的主动性特点对模型进行改进,并将其与原模型进行比较分析.通过算例分析验证了该建模方法的可行性.
Based on the basic theory of power system load modeling and the structure of electrified railway system, a model of electrified railway impact load is established. The load curve of the electrified railway impact load is denoised by wavelet analysis and used as model parameter identification. Type and AC-DC electric locomotive comprehensive load characteristics model to form electric railway impact load model structure.Model parameter identification strategy is formulated and implemented.According to the characteristics of the impact load initiative model to improve, and compared with the original model The feasibility of this modeling method is verified by an example analysis.
