The invention discloses a cable connector simulation model used in PSCAD for calculating the reclosing overvoltage of a power distribution network. The cable connector simulation model used in the PSCAD for calculating the reclosing overvoltage of the power distribution network comprises a cable middle connector resistor R, a cable middle connector inductor L and a capacitor C between a cable connector core and a shielding layer; a first port is connected with one end of the cable middle connector resistor R, the other end of the cable middle connector resistor R is connected with one end of the cable middle connector inductor L, and the other end of the cable middle connector inductor L is connected with a third port; the capacitor C between the cable connector core and the shielding layer is divided into two parts of a first capacitor C1 and a second capacitor C2; one end of the first capacitor C1 is connected with one end of the cable middle connector resistor R, and one end of thesecond capacitor C2 is connected with the other end of the cable middle connector inductor L; the other end of the first capacitor C1, the other end of the second capacitor C2, a second port and a fourth port are connected together. Due to the fact that a wave process of the overvoltage on a cable middle connector is taken into consideration, by adopting the model to calculate the overvoltage amplitude, a result can be more precise.
