Power distribution network intelligent sensor fusing gateway function and fault detection algorithm

Abstract

The invention provides a power distribution network intelligent sensor fusing a gateway function and a fault detection algorithm. The power distribution network intelligent sensor comprises a first collection unit, a second collection unit and a collection and summarizing integrated unit, wherein the first collection unit, the second collection unit and the collection and summarizing integrated unit are installed on three phase lines respectively; the first collection unit and the second collection unit are used for collecting fault recording data of the corresponding phase lines; the collection and summarizing integrated unit is used for collecting fault recording data of the corresponding phase line, collecting the fault recording data of the other two phase lines and performing summarizing processing on the collected fault recording data of the three phase lines for fault detection; and the collection and summarizing integrated unit is also used for sending the collected fault recording data of the three phase lines to a monitoring master station for fault detection. Through the power distribution network intelligent sensor, precise sensing of voltages, currents and other parameters can be realized, and the sensor has the advantages of self-energy-taking and low power consumption; and moreover, the sensor fuses the gateway function and can realize remote transmission and sharing of line monitoring information autonomously without the need for relying on a communication terminal, and therefore working stability and reliability are improved.

Description

technical field [0001] The invention relates to the technical field of distribution networks, in particular to a distribution network intelligent sensor and a fault detection algorithm that integrates gateway functions. Background technique [0002] The existing line sensors installed on the overhead lines of the medium voltage distribution network cannot guarantee the accuracy of power grid monitoring due to simple structure and low sampling accuracy. [0003] In addition, uploading the collected data also needs to rely on the communication terminal for forwarding, which leads to low work stability and cannot guarantee the reliability of long-term work. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a distribution network intelligent sensor and fault detection algorithm that integrates the gateway function, so as to realize the accurate perception of parameters such as voltage and current in the grid monitoring...
