Intelligent measurement switch with topology identification function and topology identification method

Abstract

The invention discloses an intelligent measurement switch with a topology identification function and a topology identification method. The switch comprises a main control module, a power supply module, a metering module, a communication module, a clock module and a topology identification current generation module. The power supply module, the metering module, the communication module, the clock module and the topology identification current generation module are all connected with the main control module; the communication module is used for remote communication with an uplink device; the clock module is used for realizing the accurate clock data; the topology identification current generation module is used for generating a topology identification current signal; the metering module is used for collecting topology identification current signals and analyzing the topology identification current signals to obtain the corresponding topology positions; and the main control module is used for issuing a current sending instruction to the topology identification current generation module, receiving an output signal of the metering module, and sending the output signal to a terminal through the communication module. The intelligent measurement switch with the topology identification function and the topology identification method have the advantages of simplicity and convenience in operation, improvement of power supply reliability and power grid operation and maintenance management level, high topology identification accuracy and the like.

Description

technical field [0001] The invention mainly relates to the technical field of smart grids, in particular to an intelligent measurement switch with a topology recognition function and a topology recognition method. Background technique [0002] With the increasing investment of the State Grid Corporation in the construction of smart grids, the construction of smart grids has achieved remarkable results, and the functions of smart grids such as emergency repairs, line loss management, and anti-stealing are widely used. However, since the topology of the current system is inconsistent with the actual topology, the accuracy of the final result data is greatly reduced. In low-voltage distribution networks, missing or inaccurate network topology information is a concern. Accurate user-side phase and topology connection relationship are of great significance to the operation and maintenance management of distribution network. Typically, utilities record and manage network connect...
