Fault Location of AT Power Traction Network With Protection Wire
AT power supply system with protection wire is more complex in framework,so it has more faults.The fault point should be found out quickly and accurately to repair the power supply systems.The paper estimates the area of fault based on the cosine between different fault current.Simulation analysis on Matlab/Simulink indicates that the arithmetic is not only easy but also a small amount of calculation,and the fault location principle is accurate and effective.
