Power transmission line full-life monitoring platform based on Internet of Things terminal

Abstract

The invention discloses a power transmission line full-life monitoring platform based on an Internet of Things terminal and particularly relates to the technical field of power grids. The platform comprises the following construction steps of establishing a comprehensive microclimate disaster monitoring and early warning system based on ubiquitous power Internet of Things, and establishing a porcelain insulator degradation detection system by adopting an optical fiber sensing technology and electric field simulation analysis. By integrating Internet of Things communication, sensing, a power supply and the like, requirements of automatic energy taking, low power consumption and no maintenance can be met, the early warning capability and accuracy of new detection data can be met by introducing a decision-making tree artificial intelligence algorithm, and meanwhile, requirements of monitoring and early warning management on site and visualization can be met, so monitoring and early warning management efficiency is improved; the microclimate system performs real-time monitoring and early warning on power transmission line operation faults and microclimate disasters, and can establish an early warning model suitable for the provincial and municipal microclimate disasters, so the Internet of Things power transmission line monitoring platform is maintenance-free, low in manufacturingcost, intelligent, systematic and platform-based.

Description

technical field [0001] The invention relates to the technical field of power grids, and more specifically, the invention relates to a life-span monitoring platform of a transmission line based on an Internet of Things terminal. Background technique [0002] China has a vast territory, with long distances between power generation resources and load centers, and uneven distribution. Most of China's energy concentrations are located in the north and west, while transmission lines span a wide area. A large number of micro-meteorological environments with special terrains have obvious impacts on the operation of power systems. Due to the small area of ​​the meteorological environment, the meteorological department cannot monitor and broadcast the climate conditions of these micro-meteorological points in time, and the micro-meteorological information plays an important role in the safe operation of the power grid. The lack of systematic research on disaster early warning technolo...

Problems solved by technology

[0002] China has a vast territory, with long distances between power generation resources and load centers, and uneven distribution. Most of China's energy concentrations are located in the north and west, while transmission lines span a wide area. A large number of micro-meteorological environments with special terrains have obvious impacts on the operation of power systems. Due to the small area of ​​the meteorological environment, the meteorological department cannot monitor and broadcast the climate conditions of these micro-meteorological points in time, and the micro-meteorological information plays an important role in the safe operation of the power grid. The lack of systematic research on disaster early warning technology is mainly reflected in the strong regional pertinence, the scattered collection of meteorological information, the lack of professional micro-meteorological and micro-topographic information databases, and the use of online monitoring devices for micro-meteorological disaster monitoring, which has a small monitoring range and disaster conditions. However, the establishment of a full-life Internet of Things monitoring and early warning platform for transmission lines is based on the maintenance-free design of monitoring terminals and the architecture design of the Internet of Things network. At present, various online monitoring devices for power grids have been used on a large scale. However, the main problems that the online monitoring system is difficult to popularize and use for a long time are the large structure, large amount of maintenance and high cost.
