摘要
针对高速铁路牵引供电系统中大量再生制动能量不能得到有效利用的问题,提出一种基于铁路功率调节器(RPC)的牵引供电系统储能方案及其控制方法。首先,研究牵引供电系统储能方案的拓扑结构,分析四种典型工况下系统的能量传输特性;接着,分析RPC动态补偿电能质量的基本原理,并提出一种计及储能装置的RPC控制策略;然后,研究基于电流闭环的储能装置控制策略;最后,通过仿真算例证明本文所提出储能方案和RPC控制策略的正确性和可行性。结果表明,所采用的储能方案能有效回收利用高速铁路牵引供电系统产生的再生能量,所提出的RPC控制策略能更好地解决储能装置接入牵引供电系统后的负序和谐波电流补偿问题。
Since a large amount of regenerative energy could not be effectively utilized in the traction power supply system(TPSS) of High-speed Railways(HSR), this paper proposed an energy storage scheme based on railway power conditioner(RPC) and corresponding control strategies. The topology of the energy storage scheme was firstly analyzed as well as the energy transmission characteristics of 4 typical operating conditions. Then, the dynamic compensation principle of RPC was analyzed and an improved control strategy of RPC with energy storage system(ESS) was deduced and designed. Moreover, the control strategy of ESS was proposed on the basis of current loop control method. Finally, case studies were conducted to verify the validity and feasibility of the above design.The results show that the regenerative energy can be effectively stored and reutilized with the proposed energy storage scheme. Compared with the traditional control strategy of RPC, the improved control strategy is better to solve the negative and harmonic issues in the TPSS with ESS.
