Abstract

The invention discloses a power distribution network FTU-based fault judgment method. Power distribution network mass real-time data are obtained through equipment such as a power distribution terminal, a fault indicator and an intelligent electric meter; a Storm cluster-based power distribution network real-time streaming data analysis platform is established; the Storm cluster contains a mastercontrol node and working nodes; task scheduling and task allocation between the master control node and the working nodes are realized through Zookeeper; a streaming data processing topological structure fusing various single-phase grounding fault positioning technologies is designed; and a result is output according to criteria of different single-phase grounding fault positioning technologies and is stored. The master control node runs a Nimbus module program, and is responsible for sending codes in the Storm cluster, allocating tasks to the working nodes and monitoring the states of the working nodes.

Description

technical field [0001] The invention relates to a fault judgment method, in particular to a fault judgment method based on a distribution network FTU. Background technique [0002] Most of the grounding methods of my country's distribution network are non-effective grounding. When a single-phase grounding fault occurs, the grounding current is very small and can continue to run for 1-2 hours. of blackouts. The current solutions to single-phase-to-ground faults in distribution networks include the externally applied signal method and the fault signal method. The externally applied signal method amplifies the fault characteristics by injecting external signals, which are divided into strong injection method and weak injection method; the fault signal method directly extracts the characteristic information of line voltage and current to judge whether it is grounded, which is divided into fault steady state signal method and fault signal method. Transient signal method. [000...
