Power supply control system for adaptive CT (computed tomography) induction power picking and method of power supply control system

Abstract

The invention discloses a power supply control system for adaptive CT (computed tomography) induction power picking and a method of the power supply control system. The power supply control system comprises a CT induction power picking module, a full-wave rectification module, a self-adjustment power protection module and an energy collecting control module, wherein the CT induction power picking module picks power for current within a preset range to obtain alternating-current voltage, the full-wave rectification module performs full-wave rectification for the alternating-current voltage and then outputs direct-current voltage, the self-adjustment power protection module charges a built-in energy battery according to the direct-current voltage, the CT induction power picking module is discharged when the voltage of the energy battery is higher than protection voltage, the voltage of the energy battery is outputted when the voltage of the energy battery is lower than or equal to the protection voltage, the energy collecting control module adjusts the power supply state of a micro-power load and the charging state of a super-capacitor according to the voltage strength of the energy battery, the self-adjustment power protection module solves the problem that induction power picking cannot be automatically adjusted and protected by an existing power supply system and can automatically store electric energy and switch energy.

Description

technical field [0001] The invention relates to the technical field of electromagnetic induction, in particular to a power supply control system and method for adaptive CT induction power acquisition. Background technique [0002] my country's distribution network automation involves a wide range, but due to the lack of overall planning in the early stage, the grid structure is complex and weak, and the probability of failure is high, especially for overhead lines. According to statistics, 90% of power outages and fault disturbances occur in the distribution network; among them, finding and eliminating line fault points has become an important factor to improve the quality of power supply. The use of distribution network automation terminals (FTU (feeder terminal equipment) and DTU (switching station terminal equipment)) can realize the fault location and isolation of large segments and large branches of the main line. However, the investment in this scheme is relatively la...
