Beschreibung
Zusammenfassung:	The invention relates to the technical field of power grid voltage monitoring, and discloses a distributed voltage detection method and system for a low-voltage power distribution network, and the method comprises the steps: constructing a distributed voltage monitoring structure through a user monitoring node, a shunt monitoring node and a distribution transformer terminal, and carrying out the detection of the voltage in a layered manner, the voltage measurement state of the user monitoring node is determined through the user monitoring node, and the voltage measurement state of the user monitoring node is further judged through the shunt monitoring node, so that the detection accuracy of the voltage measurement state is improved, and the steady-state voltage time sequence data of the user monitoring node in a normal voltage measurement state is screened out; and the voltage state of the low-voltage power distribution network is determined according to the screened steady-state voltage time sequence data, s
