Intelligent substation comprehensive monitoring system based on Beidou Internet of Things

Abstract

The invention discloses an intelligent substation comprehensive monitoring system based on Beidou Internet of Things. The system comprises a monitoring main station and a monitoring station end, and the monitoring main station communicates with the monitoring station end through a Beidou communication system. The monitoring station end integrates transformer oil chromatography monitoring data, a transformer iron core grounding current, transformer infrared temperature measurement data, switch mechanical characteristic information, partial discharge information in a transformer and a switch cabinet, a temperature and humidity in the switch cabinet, a cable joint temperature, cable joint ultraviolet monitoring data, cable interlayer water immersion information, lightning arrester monitoringdata, a grounding point grounding resistance and the temperature and humidity of each power distribution chamber in a substation so as to realize all-weather full-coverage state monitoring on a main electrical equipment working condition, an electrical equipment surrounding environment and an electrical equipment safety protection condition of the substation. Linkage control is carried out on power equipment defects, abnormal information alarm and front-end alarm so that safety of power grid operation is improved, labor intensity of front-line personnel is reduced, and an enterprise operationbenefit is improved.

Description

technical field [0001] This application relates to a substation monitoring system, especially a smart substation comprehensive monitoring system based on Beidou Internet of Things. Background technique [0002] With the continuous development of the power system and the continuous improvement of the degree of automation, unattended substations have become an inevitable trend. This is also an effective measure to promote the modernization of power grid production management. At present, domestic power supply companies are fully implementing unattended transformation of substations. While upgrading the substation, it also faces the problem of being unable to effectively control the on-site environment, which poses new challenges to safe production and substation operation and maintenance. [0003] In terms of improving the service level of enterprises, the substation is a key node in serving customers. Its power supply capacity and quality, the speed and efficiency of fault re...

[0002] With the continuous development of the power system and the continuous improvement of the degree of automation, unattended substations have become an inevitable trend. This is also an effective measure to promote the modernization of power grid production management. At present, domestic power supply companies are fully implementing unattended transformation of substations. While upgrading and transforming substations, they also faced the problem of being unable to effectively control the on-site environment, posing new challenges to safe production and substation operation and maintenance.

[0003] In terms of improving the service level of enterprises, the substation is a key node in serving customers. Its power supply capacity and quality, the speed and efficiency of fault repair and fault handling all directly affect the production and life of the people. However, the existing substations lack comprehensive information on the status of electrical equipment. Coverage and monitoring, it is impossible to grasp the operation status of electrical equipment in substations at any time, and it is impossible to actively and accurately repair and quickly deal with electrical equipment defects, abnormalities and fault alarms, which reduces the level of operation and management of substations and power grids, and cannot improve the initiative of maintenance teams to repair and timeliness
