摘要
鉴于高速动车组和牵引网匹配发生谐振造成多种故障现象发生的问题,为了从电力机车变流器控制的角度解决或者抑制谐振的发生,建立了牵引网-CRH1型动车组模型。在一定条件下,构建了明显的谐振现象,并对谐振现象进行分析得出了相关结论。同时研究了两种从动车组CRH1的变流器控制抑制谐振问题的办法,所提出的电压前馈延时方法解决办法,只需要修改控制算法,无需改变硬件电路即可实现。同时也对日立公司等针对国内动车组CRH2型动车组谐振提出的减小电流增益的办法进行了仿真研究,对于这项技术的国内的成熟应用上可以提供一定的参考作用。通过Matlab/Simulink验证了构建模型的正确性和解决方法的有效性。
Various faults caused by resonance of traction network when high-speed electric multiple unit(EMU) and traction network are matching. In order to suppress resonance problems from the EMU control system,Matlab/Simulink software was used to build the united model of EMU locomotive and traction network. Based on this model,this paper constructed clear resonance phenomenon and analysed the resonance phenomenon to get related conclusions. From the control of electric multiple unit,this paper studied two ways to solve the problem of resonance,one of which the voltage feedforward delay method can be realized by changing the control algorithm and keeping the hardware circuit. At the same time,this paper did a research on another way which the gain of current was decreased to suppress resonance problems,this way was used by Hitachi for domestic CRH2 high-speed electric multiple units.The conclusions in this paper can provid certain reference function for the domestication of this technology. Matlab/Simulink simulation results show that the control methods play effectiveness of the solving method and exactness of the model.
