Unbalanced Compensation Method of Multi-Station Cooperative for High-Speed Railway Based on Multi-Agent

针对只考虑单个牵引变电站的不平衡补偿方法无法将补偿装置的安装容量进一步降低的问题,该文研究一种基于多智能体的多站协同高速铁路不平衡补偿方法。首先,研究适用于多站协同补偿的新的高速铁路不平衡补偿原理以及相应的拓扑结构;接着,分析采用多站协同补偿方式下,每个牵引变电站补偿装置的安装容量;然后,提出基于多智能体的多站不平衡补偿的协同控制策略,在有效补偿不平衡电流的同时减少主从控制器之间的通信量;最后,通过仿真算例和小容量的实验验证了所提方法的优点和有效性。仿真和实验结果表明,该方法可以有效地补偿高速铁路的不平衡电流,降低单站补偿装置33.3%的安装容量。

The unbalanced compensation(UC)methods considering a single substation of high-speed railway cannot reduce the installed capacity of the UC device.A multi-agent based UC method of multi-station cooperative compensation(MSCC)for high-speed railway was studied in this paper.Firstly,a novel UC principle of high-speed railway and the appropriate topology for the MSCC were studied.Secondly,the installed capacity of the UC device for each single substation of the MSCC method was analyzed.Then,the cooperative control strategy based on multi-agent was proposed,which could effectively compensate the unbalanced current and reduce the communication between master and slave controllers.Finally,the proposed method was verified by simulations and small capacity experiments.The results show that the proposed method can compensate the unbalance current and reduce the installed capacity of single-substation UC device by 33.3%.
