为解决高速铁路牵引供电系统负序不平衡问题,在传统基于铁路功率调节器(Railway Power Conditioner,RPC)补偿的基础上,针对所需补偿容量较大的问题,提出了多变电站RPC协同补偿的理论.并对该方法进行了详细证明,推导了在各种情况下的安装容量和补偿方法,该方法较单个牵引变电站所需RPC容量可降低1/3的补偿容量,从而减小了成本.最后,进行了仿真验证,结果表明,该多站协同补偿方法具有可行性和有效性.
In order to solve the problem of negative sequence unbalance in traction power supply system of high-speed railway, based on the traditional compensation based on Railway Power Conditioner (RPC), aiming at the problem of large required compensation capacity, Theory, the method is proved in detail, and the installation capacity and compensation method in various situations are deduced. Compared with the single traction substation, the required RPC capacity can be reduced by 1/3, and the cost can be reduced. Finally, simulation results show that the multi-station cooperative compensation method is feasible and effective.
