Title:
HIGH-FREQUENCY SIGNAL-BASED POWER CONSUMER RELATIVE POSITION IDENTIFICATION APPARATUS, METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/121887
Kind Code:
A1
Abstract:
A high-frequency signal-based power consumer relative position identification apparatus, method and device. A resonance/signal generation module is mounted in each consumer electric meter in a manner of injecting a signal and receiving the signal; and a direction discrimination module is mounted at a supply main of a branch node connected to each consumer electric meter, and can monitor a phase difference between a voltage and a current flowing through a high-frequency signal at a mounting node, and the upstream and downstream position relationship of two adjacent consumer electric meters of the direction discrimination module is determined by means of the phase difference. The resonance/signal generation module serves as a high-frequency signal generation source and receiving source, so that a signal transmission distance is greatly shortened, and a signal attenuation amplitude is reduced; moreover, the effectiveness and accuracy of obtaining the relative position relationship of the consumer electric meters are guaranteed in the manner that the direction discrimination module monitors the phase difference, and the problem that the result error of the obtained relative position of the transformer area power consumer is large by using an existing transformer area power consumer relative position discrimination method is solved.
