Abstract

The invention relates to a low-voltage power distribution area identification method, comprising the steps that a transmitting terminal is used for injecting a strong power supply voltage pulse sequence into a power grid; a receiving terminal is used for identifying the power distribution area and the phase of the power grid through detecting the voltage pulse sequence. The invention further provides a low-voltage power distribution area identification instrument, which comprises a transmitting instrument and a receiving instrument, wherein the transmitting instrument is used for injecting the strong power supply voltage pulse sequence into the power grid; the receiving instrument is used for identifying the power distribution area and the phase of the power grid through detecting the voltage pulse sequence.

Description

technical field [0001] The invention belongs to the technical field of power electronics and the field of digital signal coding. The invention relates to a detection device for a low-voltage power network station area, in particular to a low-voltage station area identification method and a station area identification device. Background technique [0002] At present, the power supply company's confirmation and management of the nature of power consumption by power users is mostly based on the information on the power consumption application form of power users, but there is a lack of effective supervision of changes in the nature of power consumption and the real nature of power consumption by power users and management, and the power consumption inspection link also lacks effective detection methods for such situations; the existing low-voltage station area centralized copying system collects residents' electric energy information, and then performs statistical processing on...
