Identification method, system and device, and readable storage medium

Abstract

The present invention discloses a zone area identification method. The method comprises the steps of: obtaining zero-crossing signals of a plurality of electrical devices; employing the zero-crossingsignals of the electrical devices to extract corresponding zero-crossing signal features; and comparing the zero-crossing signal features of the electrical devices, and determining the electrical devices having the same zero-crossing signal features in the plurality of electrical devices to be located at the same zone area. The obtained zero-crossing signals are original features in the electric system with no need for injecting any signals into a power grid and without interference for the normal operation of the power grid, there is no crosstalk between adjacent zone areas to avoid the possibility of erroneous judgement, therefore compared to the prior art, the zone area identification method is more reliable and safer. Besides, the zone area identification method does not need outage, human operation, addition of a signal injection device so as to reduce the complexity and the device cost of the electric power system. Correspondingly, the present invention further discloses a zone area identification system and device, and a readable storage medium.

Description

technical field [0001] The invention relates to the field of power system control, in particular to an identification method, system, device and readable storage medium. Background technique [0002] The power station area refers to the power supply range of a certain transformer in the power system, or the power supply area of ​​a transformer. The management, electricity cost measurement, line loss optimization, and capacity optimization of the power system are all based on the power station area. Therefore, in order to complete the above work content, it is necessary to search and identify the power station area and manage them in different regions. [0003] At present, there are generally two methods of search and identification in the power station area: manual search and terminal automatic identification. Manual search mainly adopts the method of power failure, and checks whether the user is powered off to judge the station area. This method not only consumes manpower ...

AI Technical Summary

Problems solved by technology

Manual search is mainly to use the method of power failure to check whether the user is powered off to judge the station area. This method not only consumes manpower and material resources, affects the user's power consumption, but also has the disadvantages of easy error and omission of information, and untimely update.

Terminal automatic identification includes the power line carrier method and the power line injection electrical signal met
