The partial discharge （PD） of high-voltage cables and the accessories directly affects the insulation performance of power cables. Therefore， a PD detection method for high-voltage cables based on finite-difference time-domain （FDTD） modeling is proposed. First， the FDTD method and the theory of transfer function are introduced into the cable PD detection. Besides， the FDTD model of high-voltage cables is established， and the accuracy of the model is evaluated. Then， the original pulses used to excite PD events in the FDTD model of 11 kV XLPE （cross-linked polyethylene） cables are obtained， and the relevant steps of hybrid modeling for PD detection are elaborated. Finally， the finite element calculation results of the pulse injection test are analyzed to verify the effectiveness of the proposed method. The method， also applicable to the PD detection of EPR （ethylene propylene rubber） cables， paper-insulated cables， and other cables， helps to study the relationship between the PD signals and the excitation signals of PD sources. |
