Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of power grid information management, in particular to a power grid information management system and method based on operation and distribution information fusion technology. BACKGROUND

[0002] The operation and distribution fusion technology is to deeply integrate the operation and distribution business at the organization level, the business level, the application level and the management level, to uniformly manage the operation and distribution basic file data, to establish complete "station-line-substation-box-house" topology relationship based on complete, accurate and consistent power grid equipment files, and to construct "operation and distribution network". Based on power grid GIS and power grid resource business middle platform, the operation and distribution fusion technology realizes the overall management of the whole process of distribution network planning, construction and operation, supports the accurate positioning of customer repair, intelligent order allocation, rapid judgment of distribution network low-voltage whole link fault, global power failure analysis, operation and distribution survey integration and real-time and accurate statistics of line loss.

[0003] At present, the power grid marketing side and the distribution network side respectively construct and configure the distribution automation master station system and the marketing side power consumption information acquisition system, which are two completely independent systems. The distribution automation equipment and the electric energy meter / data concentrator connected between the two systems adopt completely different data modeling and signal transmission methods. Under the current operation and distribution fusion environment, the following problems exist in realizing the interconnection of data:

[0004] 1. The data modeling methods of the two are different. The data modeling of the distribution network side only needs to classify and map the data types (remote signaling, remote measurement and remote control) for organization, and has greater flexibility. The data model of the marketing side is organized according to the characteristics of business types and terminal types (concentrator, electric energy meter, remote communication unit, etc.), and defines a plurality of different models, which has no generality and has great application limitations.

[0005] 2. The data organization methods are different, which causes that under the existing application conditions, the marketing side cannot directly obtain appropriate distribution network operation data from the distribution network side to meet the power consumption business control requirements; and the distribution network side needs to spend a lot of effort to match the protocol of the marketing side of a plurality of terminal devices to obtain the required distribution network end user side data, and the engineering application efficiency is not high.

[0006] 3. The protocol standards used by the two are different: the data transmission of the distribution network side mainly follows "DL / T 634.5104-2009 Remote Control Equipment and System Part 5104", and the data transmission of the marketing side mainly follows "Q / GDW 1376-2013 Power User Power Consumption Information Acquisition System Communication Protocol", and the data organization and transmission formats of the two are quite different and cannot be directly used.
