Court power loss active sensing method based on Internet of Things

Abstract

The invention discloses a court power loss active sensing method based on an Internet of Things. According to the method, intelligent terminals used for sensing current fluctuation parameters are sequentially arranged in all electric nodes in a to-be-detected low-voltage distribution network court, the current fluctuation parameters of the intelligent terminals are collected, a current fluctuationparameter set is established, a total-state structural topological graph of the low-voltage distribution network court is established, a loop impedance value of an electric line is calculated, whether a user line has a power loss fault or not is judged by comparing the loop impedance value with a preset threshold, finally user power loss information is acquired according to the current fluctuation parameters of a fault line, and power loss active sensing is realized. Through the method, automatic early-warning of a low-voltage distribution network fault and fault research, judgment and positioning can be effectively realized, the research and judgment accuracy and rush-repair commanding efficiency of the distribution network fault are improved, and active rush-repair service of the low-voltage distribution network court fault is realized.

Description

technical field [0001] The invention relates to the technical field of power failure monitoring of distribution networks, in particular to an active sensing method for power failure in a station area based on the networking of the Internet of Things. Background technique [0002] For a long time, when a fault occurs in the power distribution network, before the fault is reported and enters the on-site emergency repair, the fault information cannot be analyzed and accurately located. Therefore, there are often situations where power users cannot accurately describe the relevant faults when they report for repairs, and repeated repairs within the scope of power outages caused by the same fault often generate multiple work orders, etc., which brings about accurate positioning of fault sources and related equipment information when handling power faults. Accurately obtain the lag of information such as the scope of fault influence. Contents of the invention [0003] The purpo...
