Modeling and Simulation of Cable Fault Location System Based on Pulse Current
In order to solve the problem of accurate simulation of cable fault location system based on pulse current
a modeling and simulation method for location systems based on pulse current is proposed. The model of RLC series high-voltage signal generator and the linear current coupler model considering mutual inductance
self inductance
self resistance and skin effect is established
and the parameters in the model are accurately quantified. Aiming at the problem that the transfer function of linear coupler is not convergent
the secondary voltage signal is calculated using the modified transfer function. The simulation and experimental results of the actual location system based on pulse current show that the proposed model has high accuracy in calculating output signals of linear current couplers caused by cable breakdown faults
which can meet the requirements of research and development of fault location algorithms.
