Terminal substation monitoring system based on LoRa communication technology

Abstract

The invention relates to the field of wireless sensor network communication and integrated automation control of substations, and particularly relates to a terminal substation monitoring system basedon LoRa communication technology. The system comprises: detecting and processing electric parameters of each line and each node of a terminal substation, uploading the electric parameters to a monitoring industrial personal computer through the LoRa communication technology, processing, mining, calculating and analyzing the uploaded data in the monitoring industrial personal computer, generating acontrol command, issuing the control command, and controlling an operation state of electrical equipment in the terminal substation. The monitoring system can communicate with the upper level of distribution network dispatching center; and the terminal substation monitoring system has the beneficial effects that the operation is stable and reliable and the practical effect is obvious, the monitoring system can monitor the operation data of the electrical equipment of the terminal substation in real time, and realize operation data display, off-limit alarm, line splitting or integrating, reactive compensation switching, operation mode control and other functions.

Description

technical field [0001] The invention relates to the field of wireless sensor network communication and comprehensive automatic control of substations, in particular to a terminal substation monitoring system based on LoRa communication technology. Background technique [0002] The monitoring of substations and distribution stations is divided into local monitoring and remote monitoring. Remote monitoring was realized in the early 1960s. It used electromechanical relay protection devices and electronic telecontrol devices to realize remote monitoring of electrical equipment in substations and distribution stations. It was widely used in the early 1980s . The secondary part of the conventional substation is mainly composed of relay protection, local monitoring and telecontrol devices. In the 1980s, due to the widespread application of microprocessors, these devices began to adopt microcomputer technology and became microcomputer relay protection devices, microcomputer monito...

AI Technical Summary

Problems solved by technology

[0003] In the domestic power industry, most of the substations (substations) with a voltage level of 35kV and above have been fully covered by the optical fiber communication network, and the terminal substations at the end of the power network are due to their large number, complex power supply and distribution lines, and operation mode. Changeable and other characteristics, most of them are not connected to the network, and are in the blind spot of distribution network scheduling management, so it is difficult to realize automatic management of distribution network
