Embodiment 1
[0024] Example 1: Such as figure 1 Shown is a distribution network with a 35kV neutral point grounded by an arc suppression coil composed of 6 feeder lines. The G in the grid is an infinite power supply; T is the main transformer with a transformation ratio of 110kV / 35kV and the connection group is YN / d11;
[0025] T Z It is a special Z-shaped transformer for grounding of the compensation grid; L is the arc suppression coil, and R is the damping resistance of the arc suppression coil. The line uses overhead lines, overhead lines-cable hybrid lines and cable lines. The number of the six feeders is L 1 ,L 2 ,L 3 …L 6 , Where L 1 It is an overhead line with a length of 15km; L 2 It is a cable with a length of 6km; L 3 It is an overhead line with a length of 18km; L 4 It is a cable mixed line, the cable length is 5km, and the overhead line length is 12km; L 5 It is an overhead line with a length of 30km; L 6 It is a cable with a length of 8km. Set feeder L 1 The AG metallic fault oc...
