Differential thought-based low-voltage distribution network reactive compensation capacitor bank fault positioning method

The invention provides a low-voltage distribution network reactive compensation capacitor bank fault positioning method based on a difference thought, and the method comprises the steps: determining that an internal fuse has a fusing fault under the condition that first current data is 0; under the condition that the first current data are not zero, second current data are calculated through the difference thought according to the first current data; under the condition that the ratio of the first current data to the second current data is not within the first preset range, calculating a target capacitance value based on the first current data; performing simulation based on each capacitor to determine a corresponding fusing current to obtain third current data; and when the target capacitance value is not within the second preset range or the difference value between the fourth current data and the third current data is greater than the first threshold value, determining that a capacitor corresponding to the
