摘要:
随着我国高速铁路牵引供电系统的快速发展，为更好地提高牵引网的供电能力，双边供电方式的牵引网成为选择。本文分析了高速铁路双边全并联AT供电方式下的电路模型，探讨了AT吸上电流比、横联线电流比、上下行电流比与距离的关系特性，分析了传统AT牵引网故障测距原理在双边供电方式下的适应性，提出了采用双端变电所测距装置协同的测距策略，并基于Matlab/Simulink仿真验证了故障测距策略的合理性。
Abstract:
With the rapid development of the traction power supply system of high-speed railway in China, in order to better improve the power supply capacity of the traction network, traction network with double-end feeding mode has become the choice. In this paper, the circuit model of double-end full parallel AT power supply mode for the high-speed railway is analyzed, and the relationship between AT’s current ratio, cross-line current ratio, up-down current ratio, and distance is discussed. The adaptability of the traditional AT traction network fault location principle in bilateral power supply mode is analyzed, and a fault location strategy with the cooperation of two-terminal substation fault location devices is proposed. The rationality of the fault location strategy is verified based on Matlab/Simulink simulation.
