Induction power taking method, system and equipment for overhead line and storage medium

Abstract

The invention discloses an overhead line induction power taking method, system and device and a storage medium. The method comprises the following steps: S1, collecting magnetic field energy of an overhead line and converting the magnetic field energy into alternating voltage; s2, rectifying the alternating current voltage; s3, the rectified voltage is filtered; and S4, after voltage reduction and energy storage are carried out on the filtered voltage through a voltage reduction and energy storage circuit, the voltage is output to an online monitoring device on the overhead line. Required direct-current voltage can be stably output through the rectifying circuit, the filter circuit and the step-down energy storage circuit, reliable and stable power supply can be achieved for an on-line monitoring device on an overhead line, the cost is low, and the effect is good. The magnetic field energy on the overhead line is used for induction power taking, the maintenance cost and the workload caused when a storage battery is used for supplying power are greatly reduced, the device is easy to install, and the original structure of the overhead line cannot be affected.

Description

technical field [0001] The invention belongs to the field of electric power systems, and relates to a method, system, equipment and storage medium for inductive power acquisition of overhead lines. Background technique [0002] With the rapid development of smart grid, the power system has stricter requirements on power supply reliability, efficiency and security. In order to ensure the safety and reliability of power transmission and distribution, it is necessary to monitor the parameters and status of overhead lines. The detection and diagnosis device installed on the overhead line can effectively detect the real-time temperature, humidity, surrounding wind speed, load condition, line condition, insulator degradation, nearby interference and other parameters of the line, so as to judge the operation status of the line, which can help the staff to timely Find out the potential hidden dangers of overhead lines and deal with them as soon as possible, so as to effectively red...

AI Technical Summary

Problems solved by technology

Some online monitoring devices use batteries for power supply, but the battery capacity is limited and the running time is short. The battery of the device must be replaced before the end of the battery life to run normally, which greatly increases the maintenance cost of the device and the workload of the staff

In addition, the power supply of some online monitoring devices is realized by converting the energy near the overhead line into electric energy. There are many potential energy sources near the overhead line, such as solar energy and wind energy, but solar energy and wind energy are less affected by the environment and weather conditions. Large, its reliability and power density are low, and its power supply capability is poor
