Co-phase power supply technology can solve the problem of three-phase load power imbalance and cancel use of the neutral section insulator, thus being helpful to future development of high-speed railways and heavy-haul railways. The co-phase power supply system was designed by combining the YN,dll transformer and the integrated power flow controller. The traditional comprehensive compensation current detection method was improved theoretically and was applied in the co-phase power supply system. The simulation results prove as follows: The improved current detection method can test comprehensive compensation currents accurately and on real-time basis; compared with the traditional comprehensive compensation current detection method, the dynamic response velocity and steady state accuracy are improved to a certain extent.%同相供电技术能解决三相负载不平衡问题,取消电分相环节,有利于未来重载、高速铁路的发展.将YN,d11变压器和综合潮流控制器相结合构成同相供电系统.对传统型综合补偿电流检测方法进行改进并应用于同相供电系统中.仿真结果表明:改进型综合补偿电流检测方法可以实时、准确地检测综合补偿电流.相比传统型综合补偿电流检测方法,在动态响应速度和稳态准确性上都有一定的改善.
