Beschreibung
Zusammenfassung:	The invention relates to a one-point or multi-point reactive power compensation method and device of a power distribution line. The method includes the following steps that: the number of compensation points of the power distribution line is determined according to the length of the power distribution line and the number of loads; the optimal position of each compensation point on the power distribution line is determined according to the number of the compensation points, the length and resistance of the power distribution line and the number of the loads; the optimal compensation capacity of each compensation point is determined according to the number of the compensation points, the number of the loads of the power distribution line and the reactive power of the power distribution line; reactive power compensation is performed on the power distribution line according to the optimal position of each compensation point on the power distribution line and the optimal compensation capacity of each compensation
