Embodiment 1

[0021] A substation intelligent detection system based on the ubiquitous power Internet of things is used for fault detection of the power grid system with the ubiquitous power Internet of things, such as figure 1 As shown, including, build the sensor table, the sensor table records the sensor L i name, detected device information, and detected values.

[0022] Establish the sensor early warning value table, the sensor early warning value table records each sensor L i detection value of Sensors include primary equipment operating temperature monitoring sensors, lightning arrester leakage current monitoring sensors, video monitoring image sensors, perimeter anti-intrusion sensors, tower anti-theft monitoring sensors, SF6 gas density monitoring sensors, fire smoke detection sensors and rain sensors .

[0023] Establish a sensor cooperation table, and the sensor cooperation table records each sensor L i Collaborative Sensor L i-k A list of collaborative sensors L i-k for d...

Embodiment 2

[0028] This embodiment is further improved on the basis of the first embodiment. Specifically, the power grid is divided into several regions according to the voltage level, the nodes whose voltage level changes are attributed to the higher voltage level area, and the area is regarded as a subnetwork. An edge server is established for each subnet, and the sensors in the subnet are connected to the corresponding edge server.

[0029] Create early warning portraits of equipment failures, such as image 3 As shown, the establishment of the equipment fault warning image includes the following steps: enumerate the sensor L that detects the equipment i ; get sensor L i detection value of The historical value of and the historical fault data of the equipment; calculate the sensor L i detection value of Correlation with equipment failure, selected detection value A number of sensors L whose correlation with the fault is higher than the set threshold i ; will be selected sens...

Abstract

The present invention relates to the technical field of power equipment fault detection, in particular to a substation intelligent detection system based on the ubiquitous power Internet of Things, including establishing a sensor table, establishing a sensor early warning value table; establishing a sensor cooperation table; when the sensor L i When the detection value exceeds its safety interval, read the sensor L according to the sensor cooperation table i Collaborative Sensor L i‑k The detection value and judge whether there is a device failure, and if there is a failure, an alarm will be issued. The substantive effects of the present invention are: through the sensor early warning value table, the faults and abnormalities existing in the power grid system can be found in time, and the maintenance personnel can be guided to check and repair; by establishing equipment status portraits and equipment failure early warning portraits, early warning of equipment failure can be provided , reduce the number of failures of power grid equipment, and reduce the impact loss of failures; by dividing subnets and establishing edge servers, communication expenses can be reduced and detection efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of power equipment fault detection, in particular to a substation intelligent detection system based on the ubiquitous power Internet of Things. Background technique [0002] With the development of the economy, users' demand for electricity increases rapidly. At the same time, users have higher requirements for the stability of power supply. The scale of the power grid is also expanding. In order to meet the needs of users for power and stability, a large number of smart devices are used in the construction of the power grid. With the continuous construction of the communication network, the establishment of a sound detection network has a technical foundation and has been gradually promoted, and gradually formed the Internet of Things. The power Internet of Things can comprehensively detect the various working states of power grid equipment, improving the quality and efficiency of power grid monitoring. ...
