摘要: 针对电气化铁路节能增效及谐波治理问题,提出一种考虑特征次谐波治理的铁路牵引网侧储能系统控制策略。首先,分析牵引网侧储能系统接入方案并对其工作模态进行划分;其次,根据牵引负荷特征次谐波分布规律,推导网侧储能系统削峰填谷及特征次谐波治理方法;然后,提出一种计及网侧特征次谐波抑制的超级电容储能系统控制策略;最后,通过多工况下仿真测试,验证了所提策略的可行性。结果表明,所提策略能有效回收再生制动能量,减小网侧功率波动,抑制网侧特征次谐波。

Abstract: Aiming at the problems of energy saving, efficiency improvement and harmonic control of electric railways, a control strategy of railway traction network-side energy storage system is proposed with consideration of characteristic harmonic control. Firstly, the access scheme of the traction network-side energy storage system is analyzed and its working modes are classified. Secondly, according to the distribution of characteristic harmonics of traction load, a novel method is deduced for peak load shaving and characteristic harmonics control by using the energy storage system at the grid side. And then, a control strategy of supercapacitor energy storage system is proposed, which takes into account the grid-side characteristic harmonic suppression. Finally, the feasibility of the proposed strategy is verified by simulation tests under multiple working conditions. The results show that the proposed strategy can effectively recover the regenerative braking energy, reduce the power fluctuation, and suppress the characteristic harmonics at the grid side.
