A power fluctuation suppression method for high-power online induction energy harvesting device used in 110kv high-voltage line wireless energy supply system

Abstract

The invention discloses a method for suppressing the power fluctuation of a high-power online induction energy-fetching device for a 110kV high-voltage line wireless energy supply system. The iron core air gap and the number of turns of the secondary winding are matched to suppress the output power fluctuation of the induction energy-fetching device. It can not only increase the output power of the induction energy-fetching device when the high-voltage line current is small, but also properly discharge its energy-fetching power when the high-voltage line current is large, thereby greatly reducing the on-line induction energy-fetching device caused by the change of the high-voltage line current. The impact on the load caused by the sharp change of the output power achieves the purpose of maintaining a relatively stable output power in the case of wide-range fluctuations in the high-voltage line current. When the high-voltage line real-time current fluctuates between 0.5 and 1 times the designed working current, ensure that In order to obtain the output power of the device to meet the load power requirements.

Description

technical field [0001] The invention relates to a power fluctuation suppression method for a high-power induction energy harvesting device, in particular to a power fluctuation suppression method for an online induction energy harvesting device used in a 110kV high-voltage line wireless energy supply system. Background technique [0002] With the continuous deepening of industrialization, the demand for industrial electricity has also increased sharply. The high-voltage transmission line is shouldering an increasingly heavy historical mission and shouldering the responsibility of linking the coordinated economic development between the east and the west. However, due to the long span between poles and towers of high-voltage transmission lines, the operating environment is mostly in remote areas such as the wild and suburbs, and is easily affected by severe weather such as strong winds, rain, snow, and haze. , pollution, tower tilt, bird damage and other hazards, more seriou...
