Method and system for monitoring low-voltage power grid equipment

Abstract

An embodiment of the invention provides a method for monitoring low-voltage power grid equipment. The method includes: setting up a low-voltage power grid equipment data base comprising graphic data and attribute data of the low-voltage power grid equipment; receiving low-voltage power grid equipment ID (identification) number inputted by a user; extracting corresponding graphic data and attribute data of the low-voltage power grid equipment from the low-voltage power grid equipment data base according to the ID number; associating the low-voltage power grid equipment according to a preset service mode; and revealing low-voltage power grid information to a client according to a monitoring request to facilitate monitoring, wherein the low-voltage power grid information includes graphic information, attribute information and associated information of the low-voltage power grid equipment. The embodiment of the invention further provides a system for monitoring the low-voltage power grid equipment. Using the method and the system for monitoring low-voltage power grid equipment can realize unified monitoring and management of the low-voltage power grid equipment in the whole power distribution substation and improve monitoring efficiency of the power grid equipment.

Description

technical field [0001] The invention relates to the technical field of power systems, in particular to a method for monitoring low-voltage power grid equipment and a corresponding system. Background technique [0002] The power system has established a production information system for high and medium voltage power grids, through which real-time monitoring and analysis of high and medium voltage power grid equipment can be realized. However, for low-voltage power grid equipment, due to the large number of low-voltage equipment, scattered geographical locations, and large differences in the characteristics of each equipment, centralized and unified management of equipment information has not yet been realized, and low-voltage information monitoring in power distribution and transformation areas cannot be carried out.

AI Technical Summary

Problems solved by technology

However, for low-voltage power grid equipment, due to the large number of low-voltage equipment, scattered geographical locations, and large differences in the characteristics of each equipment, centralized and unified management of equipment information has not been realized, and low-voltage information monitoring in distribution and transformation areas cannot be carried out.

At present, signal acquisition devices for low-voltage equipment have appeared on the market, but the information obtained by these acquisition devices is usually only the status information of low-voltage equipment, and cannot provide ledger data for low-voltage equipment

Moreover, due to the interests of the provider of the signal acquisition device, the collected data formats are incompatible with each other, and the data is scattered and stored in multiple microcomputers in different locations, which makes it impossible for the power company to effectively protect and manage the data of these low-voltage equipment. Unable to meet the fine-grained use requirements of the production department for low-voltage equipment data

In addition, the data in each microcomputer must be managed manually. On the one hand, this method wastes manpower and material resources. On the other hand, it is prone to problems such as missing data and low accuracy. Automatic correlation statistics of data cannot be realized.
