Intelligent substation state monitoring system based on ubiquitous power internet of things

Abstract

The invention provides an intelligent substation state monitoring system based on ubiquitous power Internet of Things. The system comprises a sensing layer, a network layer, a platform layer and an application layer, and is characterized in that the sensing layer comprises a plurality of sensors for acquiring state data of each power device in a substation, and an intelligent inspection device; data collected by the sensing layer is transmitted to the network layer in a wireless communication mode; the network layer integrates the state data, collected by the sensing layer, of power devices,and transmits the integrated state data of the power devices to the platform layer in a wireless communication mode; the platform layer transmits the received state data of the power devices to the application layer in a wireless communication mode; and the application layer comprises a plurality of visualization devices and is used for achieving visualization of state monitoring data of all powerdevices in a transformer substation. According to the invention, real-time monitoring and risk assessment of the power devices in the transformer substation are realized, and the comprehensive perception ability of workers to the equipment in the transformer substation is improved.

Description

technical field [0001] The invention relates to the technical field of substation status monitoring, and more specifically, to an intelligent substation status monitoring system based on the ubiquitous power Internet of Things. Background technique [0002] The construction of the Ubiquitous Power Internet of Things is an important measure to realize the Energy Internet. The Ubiquitous Power Internet of Things includes the interconnected power network and communication network. The traditional Internet of Things mainly emphasizes the interconnection of information, while the Ubiquitous Power Internet of Things has the existing power Interconnection, and information interconnection. Throughout the power system, in order to ensure the safety and stability of the system, a state monitoring system including data acquisition and monitoring can be installed on various equipment in the transmission circuit or substation. [0003] But for now, substations are mainly on duty manuall...

AI Technical Summary

Problems solved by technology

The manual inspection operation method is not comprehensive enough to monitor the equipment in the substation. On the other hand, the judgment and risk assessment of the operation status of each equipment in the substation may lead to large deviations based on the personal experience of the inspectors, and there are huge obstacles in the interconnection of information.

[0004] Taking infrared temperature measurement as an example, the existing software can only display the high-temperature points in the monitoring image, and cannot automatically locate the high-temperature fault area by merging with the visible light image, nor can it automatically identify the fault type, and the monitoring data cannot be uploaded in real time and compared with historical data. The image and video monitoring system in the substation mainly uploads the monitored data to the data center. This method cannot automatically identify useful data from the massive database, which brings great difficulties to the staff for data screening, analysis and processing. heavy workload

In addition, a large amount of image data generated by manual inspection cannot be classified and marked in time, which brings great inconvenience to later analysis and archiving
