高速铁路AT供电系统谐波谐振频率研究
|
摘要
给出了一种简便、直接计算牵引供电系统的谐波谐振频率的方法。通过对AT(autotransformer)供电方式下的单线牵引网进行三导体合并化简和去耦,得到其单位长度阻抗、电容。采用双端口网络对AT供电系统进行等效分析,获得牵引供电系统谐振频率的精确表达式。根据牵引网单位长度阻抗、电容及已知的牵引网长度即可推导出该牵引网的谐振频率。采用Matlab软件进行仿真分析,结果表明:通过该方法计算得到的牵引网谐振频率与仿真得到的谐振频率一致,证明了该方法的正确性。
A simple and straightforward method for calculating the harmonic resonance frequency of a traction power supply system is proposed in this paper. The unit length impedance and capacitance of traction network are obtained by the three-conductor simplification and decoupling of the single-wire traction network under the AT power supply mode. Then the expression of traction power supply system resonant frequency is derived when the two-port network is used to analyze the equivalent circuit of AT Traction power supply system. The resonant frequency of the traction network can be derived from the unit length impedance of the traction network, the capacitance and the known length of the traction network. The simulation is done in the MATLAB software, and the results show that the harmonic resonance frequency of AT traction power supply system obtained by this method is consistent with the simulated resonant frequency, which verifies the correctness of this method.
