Distributing line fault detection system based on cloud server

Abstract

The invention relates to a distributing line fault detection system based on a cloud server. The distributing line fault detection system comprises the cloud server and data management subsystems arranged on all area line monitoring points of a power distribution network respectively; voltage and current signals of power supply lines are collected, and the voltage and current signals of the powersupply lines are weak electric signals obtained in the mode that all the voltage and current signals of the power supply lines are converted by a voltage current transformer respectively; switch datacollecting modules are used for collecting action characteristics of switches and signals of the temperatures of contactors; the line monitoring points are subjected to forecast judgment of fault types according to data matched in an overhauling log base; the monitoring points subjected to forecast judgment of fault types according to judging modules are further subjected to fault warning identification reminding, and forecast fault position information of the corresponding monitoring points is further sent to mobile terminals of area maintenance persons of faults.

Description

technical field [0001] The invention belongs to the technical field of power supply, and in particular relates to a cloud server-based power distribution line fault detection system. Background technique [0002] With the rapid development of the economy and the large increase in power load, higher and higher requirements are put forward for the reliability and quality of power supply. The distribution network is directly oriented to users and has the most direct impact on the quality and reliability of power supply for users. Compared with the transmission network, the distribution network protection and control device configuration is relatively simple, and it is extremely vulnerable to failures caused by various factors. According to statistics, most power outages are caused by distribution network failures. The power system distribution network has a large number of feeders, a wide range of power supply, and a huge number of equipment. When a line fails, not only the lo...

Problems solved by technology

In order to find out the specific fault location, it is often necessary for the operator to pull the power outage and manually inspect the line to find the fault point, which takes a long time, consumes a lot of manpower and material resources, easily prolongs the power outage time, and reduces the reliability of power supply
