Embodiment Construction
[0019] see figure 1 and figure 2 As shown, the present invention is a cable joint simulation model for calculating distribution network reclosing overvoltage in PSCAD, including cable intermediate joint resistance R, cable intermediate joint inductance L, and capacitance C between cable joint core and shielding layer .
[0020] Port 1 is connected to one end of the cable intermediate joint resistance R, the other end of the cable intermediate joint resistance R is connected to one end of the cable intermediate joint inductance L, and the other end of the cable intermediate joint inductance L is connected to port 3; the cable joint core and the shielding layer The capacitor C is divided into two equal parts: the first capacitor C1 and the second capacitor C2, the capacity of the first capacitor C1 and the second capacitor C2 are both C / 2; one end of the first capacitor C1 is connected to one end of the cable intermediate joint resistor R, One end of the second capacitor C2 i...
