In order to ensure the safe operation of power cables,a VR-based ground fault detection simulation system for power cables is proposed.The main fault types at the ground fault point of the power cable are analyzed,and the hardware part of the system is constructed.Through VR technology and modern computer technology,three-dimensional modeling of power cable line scene is carried out.Familiarize with the composition and structure of power cable,replica wavelet transform is used to extract low frequency current generated by low-frequency sinusoidal signal generator,and obtain different branches according to the resistive component of calculated current signal.The grounding resistance of the circuit is determined,the fault point is judged,and the ground fault point detection of the power cable is finally realized.The simulation results show that the proposed system can obtain high-accuracy detection results of ground fault points of power cables.
