Abstract
In this paper, real-time monitoring of acoustic emission power GIS equipment is studied and analyzed, and a real-time wireless sensing monitoring system is designed. The overall design of the wireless sensing monitoring system for acoustic emission power GIS equipment is as follows: the model of the system is constructed, the design of the system module function is proposed, the platform of the system is built, the hardware and software solutions are configured, the operating system is optimized, the graphics and data are input into the GIS distribution network system, the editing function is optimized, the fast positioning function of the equipment is improved, and the automatic generation of the system diagram is improved. By using ZigBee technology to establish a wireless sensor network and realize wireless transmission of monitoring signals, it can avoid many disadvantages, such as cumbersome cable laying, troublesome changes, inconvenient expansion, and daily maintenance in wired transmission, and save various resources and reduce monitoring costs, which is well worth promoting in the system. In this paper, for the actual situation of GIS equipment, combined with the characteristics of the wireless sensor network structure and the design needs of the monitoring system (the overall design of the monitoring system, OFS maximum response amplitude of 19.9 mV, to be reached 40 dB), the signal will be uploaded to the high-speed collection system, and the efficiency is increased by more than 10%. The feasibility test of the monitoring system, the test results, and the related data show that the UHF sensor can accurately collect the UHF signal, the wireless network formed by ZigBee can reliably transmit the signal, the monitoring interface is correctly displayed, and the whole monitoring system operates stably and meets the requirements of the initial design.
Highlights
With the development of society and economy, as well as the progress of science and technology, the safety of electric power systems is closely related to social stability, and the normal operation of electric power equipment is necessary to ensure the normal operation of the electric power systems
As important component equipment of substations, transformers and GIS will lead to the paralysis of power systems once the failure occurs, which will lead to serious loss; it becomes especially important to ensure the normal operation of transformers and GIS
Electrical equipment mainly consists of conductors, magnetic conductive materials, insulating materials, and operating mechanisms, and the failure of electrical equipment can be divided into three categories: mechanical failure, conductor failure, and insulation failure [1]; insulation failure in the electrical equipment failure in the proportion of the larger, so the insulation status of electrical equipment monitoring and regular maintenance, can avoid part of the insulation failure, to avoid causing greater losses
Summary
With the development of society and economy, as well as the progress of science and technology, the safety of electric power systems is closely related to social stability, and the normal operation of electric power equipment is necessary to ensure the normal operation of the electric power systems. The wireless sensor network holds the current international attention and is a multidisciplinary frontier hot research field; the ZigBee technology is applied to the local in-line monitoring of GIS equipment in the power system, improves the level of automation, intelligence, and digitalization of substations, and reduces personnel monitoring costs and comprehensive wiring costs, in line with the requirements of strong smart grid construction On this basis, run the basic applications of distribution network production and dispatching, unify business specifications, improve the modern management level and production efficiency of regional distribution networks, and solve the practical tasks of distribution network management, mainly involving the spatial GIS information display and some spatial analysis functions, integration of production management data and distribution network verification. Spatial analysis, and spatiotemporal analysis to provide a scientific basis for the development of power generation management, integrate multidimensional information, such as power supply network information and equipment usage information, integrate and develop modules for managing power equipment and operation management, and provide modern production management tools
