Electromagnetic energy collecting device and stable power supply system for smart power grid

Abstract

An electromagnetic energy collecting device for a smart power grid comprises a strip-shaped magnetic core, wherein magnetic collecting plates are fixedly connected to the two ends of the magnetic core, the sectional area of each magnetic collecting plate is larger than that of the magnetic core, and a coil is wound around the magnetic core. A stable power supply system for the smart power grid comprises the electromagnetic energy collecting device, a storage module and an output module, wherein the storage module is electrically connected with the electromagnetic energy collection device and is used for storing the electric energy collected by the electromagnetic energy collection device; and the output module is electrically connected with the storage module and is used for outputting the electric energy stored in the storage module to a load device. The provided electromagnetic energy collection device and the provided stable power supply system for the smart power grid can efficiently collect electromagnetic energy near a power transmission line, supply power to monitoring equipment such as a sensor and ensure stable operation of the smart power grid.

Description

technical field [0001] The invention relates to the field of smart grids, in particular to an electromagnetic energy collection device and a stable power supply system for smart grids. Background technique [0002] With the acceleration of the country's urbanization process and the increase of various electrical equipment, the power load will increase significantly. For the original power grid, on the one hand, it is necessary to increase the current of the transmission line and increase the voltage level for power transmission; on the other hand, as time goes by, the power grid will experience aging and other phenomena. In order to ensure the safe and stable transmission of electric energy, and to detect problems in time, the power sector often uses condition monitoring equipment to monitor the meteorological elements (temperature, humidity, wind speed and wind direction) around the power line, the current, temperature and gradient of the power line, etc., in a certain In ...

Problems solved by technology

Among them, the contact device is closer to the power line, has a closed magnetic circuit, and collects more energy. Therefore, most researches focus on the contact energy harvesting device, but the contact device will increase the weight of the power line and the maintenance and installation are more complicated; The non-contact device is easy and flexible to install, but the magnetic circuit is no longer closed, and the energy harvested is small
