Transformer area identification method based on zero-crossing NTB

Abstract

The invention discloses a transformer area identification method based on zero-crossing NTB. The method comprises the following steps: respectively acquiring score groups of all central coordinators in a region to which a to-be-identified station belongs; based on all the score groups, acquiring an identification result through a preset identification mode, and returning the identification result to all the central coordinators, wherein the step of acquiring the station NTB sequence by performing transformer area feature acquisition on the to-be-identified station comprises the following steps: determining a local central coordinator from all central coordinators in an area to which the to-be-identified station belongs; converting the beacon timestamp of the to-be-identified site and the beacon timestamp of the central coordinator into the beacon timestamp of a local central coordinator; calculating the delay time of the to-be-identified site based on the converted beacon timestamp of the to-be-identified site and the converted beacon timestamp of the central coordinator; setting a high-precision timer based on the delay time, and collecting the feature data through a zero-crossing NTB collection method to obtain a site NTB sequence of the to-be-identified site. The transformer area identification method based on the zero-crossing NTB has better identification stability and higher identification precision.

Description

technical field [0001] The invention relates to the field of power carrier technology, in particular to a zero-crossing NTB-based station area identification method based on the State Grid's "Technical Specifications for Interconnection and Interconnection of Low-Voltage Power Line High-speed Carrier Communication". Background technique [0002] Accurately establishing the relationship between households and transformers in the station area is the key to ensure accurate calculation of the line loss in the station area. The use of station area identification technology can identify the working station areas of different HPLC networks, thereby improving the accuracy of judgment of the relationship between households and transformers, which is conducive to the calculation of line loss in the station area. management, and improve the level of economic operation of the power grid.
